Jesus of Nazareth died, probably around 30 CE, as a Jewish teacher executed by the Roman authorities. Three centuries later, bishops from across the Roman world met under imperial patronage to define the relationship between Jesus and God. By then Christianity was concerned not only with what Jesus had taught, but with what Jesus was.
Jesus left no writings of his own. The Gospels preserve accounts of what he was remembered as doing and saying, and in the Synoptic Gospels especially the emphasis is far more on narrative and teaching than on developed theology. They do not claim to record everything: Luke says that “many” had already attempted accounts before him (Luke 1:1–4), while John acknowledges that much more could have been written about Jesus (John 21:25). What we possess is therefore a selection from the remembered material, not a complete record. Any attempt to construct a theology beyond what those texts actually say is necessarily an extrapolation from them.
The earliest surviving Christian documents are the letters of Paul, written from about 50–60 CE, roughly twenty years after Jesus’ death. Unlike the Gospels, they are not attempts to narrate Jesus’ life. They are theological letters concerned with the meaning of his death and resurrection, the status of Christ, sin, salvation, the Law, faith and the inclusion of Gentiles. Paul was working from traditions he had received from other believers as well as from his own claimed revelation of Christ (1 Corinthians 15:3–5; Galatians 1:15–16).
Paul’s letters were initially addressed to particular communities, and we do not know how widely they circulated in the first decades after they were written. By the second century, Paul had become a major theological authority in several competing forms of Christianity. Marcion made his letters central to his canon, Valentinian Christians interpreted them in support of their own theology, while writers such as Irenaeus claimed Paul for the emerging orthodox tradition.
The Gospel now known as Mark is usually dated around 65–75, those known as Matthew and Luke around 80–90, and John around 90–100. Acts, written by the same author as Luke, is commonly dated around 80–90. The traditional names attached to the four Gospels do not by themselves establish who actually wrote them. The New Testament is therefore not arranged chronologically: several of Paul’s letters are older than any surviving Gospel.
The investigation of early Christianity is hampered by the survival of only a small and uneven body of evidence. We have a handful of letters, several narrative accounts, fragments, later quotations and texts preserved by communities that survived. What was never written down, what was lost, what ceased to be copied and what was deliberately rejected can only occasionally be recovered. The history of the first generations of Christianity therefore has to be reconstructed from evidence that is both limited and selective.
The comparatively narrative character of the Gospels suggests that the example and teaching of Jesus remained at the forefront of Christian memory, even while theological interpretations of his significance were already developing elsewhere.
The idea that these writings together formed the unerring Word of God was itself a later development. They were composed at different times, by different authors, for different communities, and only gradually collected into a Christian canon. Early Christians regarded scripture as inspired and authoritative, but the Reformation principle of sola scriptura (the authority of scripture alone), associated above all with Martin Luther (1483–1546) and developed by other Reformers such as Huldrych Zwingli (1484–1531) and John Calvin (1509–1564), arose in opposition to doctrines and practices which they believed lacked sufficient scriptural foundation. Indulgences were an obvious target, while disputes also extended to papal authority, purgatory, the cult of saints and other elements of Catholic tradition. Once scripture became the supreme authority, later Protestantism developed increasingly precise doctrines of biblical inerrancy, especially in American evangelical and fundamentalist circles during the nineteenth and twentieth centuries.
Before the earliest surviving narrative of Jesus’ life had been written, Paul was already interpreting the significance of Jesus’ death and resurrection. The Synoptic Gospels present a teacher whose message repeatedly returns to two themes: the Kingdom of God and love of neighbour. Jesus is presented as announcing that the Kingdom of God has come near (Mark 1:14–15), making it central to his preaching and parables (Matthew 13; Luke 4:43; 8:1), and identifying love of God and neighbour as the greatest commandments (Mark 12:28–34; Matthew 22:34–40; Luke 10:25–37). Around these themes gather forgiveness (Matthew 6:12–15; 18:21–35), reconciliation (Matthew 5:23–24), mercy (Luke 6:36–37), generosity (Luke 12:33; 14:12–14), criticism of hypocrisy (Matthew 23) and suspicion of wealth (Mark 10:17–27; Luke 6:24–25; 16:19–31).
Paul’s letters have a different centre. They concentrate on Christ crucified and risen, sin, death, salvation, faith, resurrection and the Spirit. Paul can summarise his preaching as “Christ crucified” (1 Corinthians 1:23) and describes Christ’s death, burial and resurrection as matters “of first importance” (1 Corinthians 15:3–8). Romans develops an extended argument about sin, justification, death, new life and the Spirit (Romans 3–8). The Kingdom remains in Paul’s vocabulary, but the emphasis has moved strongly towards the meaning of Christ himself.
Paul’s history before his conversion belongs to that story. He presents himself as a thoroughly committed Jew: “circumcised on the eighth day,” “of the people of Israel,” “of the tribe of Benjamin,” “a Hebrew of Hebrews,” and “as to the law, a Pharisee” (Philippians 3:5–6). In Galatians he says that he had advanced in Judaism beyond many contemporaries and had been “extremely zealous” for ancestral traditions (Galatians 1:13–14).
Paul also says that he persecuted the early Christian movement (Galatians 1:13; 1 Corinthians 15:9; Philippians 3:6). Acts gives the persecution a fuller narrative form, portraying Saul as approving Stephen’s killing (Acts 7:58; 8:1), ravaging the Church (Acts 8:3) and seeking authority from the high priest to arrest followers of “the Way” in Damascus (Acts 9:1–2). In later speeches Acts has Paul say that he acted with authority from the chief priests (Acts 22:4–5; 26:10–12).
Acts also identifies Paul as a Roman citizen (Acts 16:37–38; 22:25–29; 23:27). Roman citizenship would have given him legal privileges, but there is no evidence that Rome employed or paid him to persecute Christians. Paul’s own letters associate his persecution with religious zeal, while Acts attributes his authority to Jewish religious leaders. These are claims within the surviving sources, not independent proof that every detail happened exactly as described.
Paul clearly did not begin as someone who accepted Jesus as Messiah. Crucifixion itself presented a theological difficulty. Deuteronomy declares that one who hangs on a tree is under a curse (Deuteronomy 21:22–23), a passage Paul himself later uses when interpreting Christ’s death (Galatians 3:13). The proclamation that a crucified man was God’s Messiah could therefore have appeared not merely mistaken but offensive to a zealous Jew.
Acts tells the conversion story three times (Acts 9:1–19; 22:6–16; 26:12–18), with a light from heaven, a voice and Paul’s temporary blindness. Paul himself gives a much briefer account. He says that God “was pleased to reveal his Son” to him (Galatians 1:15–16). The phrase does not imply that Paul was the first person to regard Jesus as God’s Son. Paul elsewhere quotes or transmits traditions which appear to predate his conversion (1 Corinthians 15:3–5), showing that belief in Jesus’ resurrection and exalted status was already present among his followers. Paul’s claim is personal: the Jesus whom he had rejected was revealed to him as God’s Son, and Paul understood himself to have been commissioned to preach that message to the Gentiles.
Belief that Jesus was uniquely related to God had therefore emerged very early, certainly within the first generation after his death. By the time Paul was writing in the 50s CE, Christians were already speaking of Jesus as God’s Son, proclaiming his resurrection and attributing to him an exalted status which went far beyond that of an ordinary teacher.
Whatever occurred, Paul became convinced that the movement he had opposed was founded upon a truth he had failed to recognise. If he had believed that persecuting Christians was an expression of loyalty to God and then came to believe that God had vindicated Jesus, his previous assumptions about righteousness, Law and divine favour required reconstruction. Paul later contrasts his former confidence in legal righteousness with what he subsequently found in Christ (Philippians 3:4–11).
We cannot know how far guilt, shock or inner conflict entered into that reconstruction. His mysterious “thorn in the flesh” (2 Corinthians 12:7–10) cannot safely be identified with any particular physical or psychological condition. Nor can Acts’ account of Stephen’s death tell us what effect, if any, that event had upon Paul internally. What survives is the theology produced after Paul’s reversal, and that theology became one of the foundations of Christianity.
The Greek word Christos means “anointed one”, the equivalent of Messiah, but in Paul it is so frequently attached to Jesus — as Jesus Christ, Christ Jesus or simply Christ — that it often functions more like a name than a title. Paul can also speak of Christ in terms extending well beyond the earthly life of Jesus. Philippians describes Christ as being “in the form of God” before taking “the form of a slave” (Philippians 2:6–11), while 1 Corinthians speaks of “one Lord, Jesus Christ, through whom are all things” (1 Corinthians 8:6). An exalted interpretation of Christ was therefore present within a generation of Jesus’ death.
The Gospels in the forms in which we know them were composed later than Paul’s letters, although they drew on earlier traditions and probably earlier written material, and the circumstances in which they acquired their present form remain surprisingly obscure. We do not know their authors with certainty, exactly where most of them were written, who first assembled the traditions they contain, or why particular versions survived while others disappeared. Their traditional titles are ancient, but the texts themselves do not identify their authors in the manner of a modern signed work.
Mark is generally regarded as the earliest Gospel. Matthew and Luke appear to have used Mark together with other material, while John differs markedly in language, chronology and theology. The four accounts overlap but also diverge. Matthew and Luke give different infancy narratives (Matthew 1–2; Luke 1–2); Mark gives none; John begins instead with the pre-existent Logos: “In the beginning was the Word” (John 1:1–18). John’s Jesus visits Jerusalem repeatedly (John 2:13; 5:1; 7:10; 12:12), whereas the Synoptic Gospels concentrate much of his ministry in Galilee before a final journey to Jerusalem. The timing of the Last Supper and crucifixion also differs: the Synoptics present the meal as a Passover meal (Mark 14:12–17; Matthew 26:17–20; Luke 22:7–15), while John’s chronology places Jesus’ death before the Passover meal (John 18:28; 19:14).
Luke acknowledges that “many” had already attempted narratives before he composed his own account (Luke 1:1–4). That brief remark opens a window onto a much larger world of lost material. Sayings, stories and written accounts circulated before the surviving Gospels reached the forms in which we know them. Numerous early Christian papyrus fragments have since been discovered, showing that Gospel and other Christian writings were being copied and circulated by the second century. Most survive only in fragments, and the manuscript record becomes substantially fuller only later.
The discovery of the Nag Hammadi library in Egypt in 1945 added another body of evidence. The surviving codices are mostly fourth-century manuscripts, but many of the works they preserve were composed much earlier, often in the second century. They include gospels, revelations, dialogues and theological works reflecting Christian traditions which did not enter the New Testament. The Gospel of Thomas, Gospel of Philip, Apocryphon of John and other writings belong to a Christian literary world much larger than the twenty-seven books later gathered into the New Testament.
By the later second century the four canonical Gospels had nevertheless acquired a privileged position in substantial parts of the Church. Tatian, c. 120–180, combined Matthew, Mark, Luke and John into his Diatessaron around 170, while Irenaeus, c. 130–202, writing around 180, insisted that there were and should be four Gospels. Somewhere between the composition of the individual works and the late second century, Four particular narratives had emerged from what was probably a much wider body of tradition and acquired exceptional authority.The stages by which that happened can only partly be reconstructed.
The documentary beginnings of Christianity are therefore remarkably modest and uncertain. Four relatively short anonymous narratives, composed decades after Jesus’ death out of traditions whose earlier history is only partly recoverable, became the principal narrative accounts of his life. From those texts, together with Paul’s letters and other writings, grew the theological and institutional structure which eventually defined who Jesus was for much of the world.
Acts carries the story from Jesus to the expanding Church. Its programme is announced at the beginning: the disciples are to bear witness “in Jerusalem, in all Judea and Samaria, and to the ends of the earth” (Acts 1:8). Peter dominates the early chapters, but Paul increasingly dominates the later ones. The book begins in Jerusalem and ends with Paul preaching in Rome (Acts 28:16–31). A Jewish movement centred on Jerusalem is presented as becoming a mission extending throughout the Roman world.
Arguments were already occurring within the earliest communities. Acts and Galatians preserve disputes over circumcision and the Law for Gentile converts (Acts 15; Galatians 2:1–14; 5:1–12). Paul discusses disagreements over food, observance and relations between Jewish and Gentile believers (Romans 14; 1 Corinthians 8; Galatians 2). Disagreement therefore preceded the later disputes over Christ’s nature.
There was no fixed twenty-seven-book New Testament available to settle those arguments. The writings now bound together originally circulated independently or in smaller collections, alongside other texts which later disappeared, were rejected, or survived outside the canon.
Marcion, c. 85–160, confronted the difficulty of reconciling the God proclaimed through Jesus with violent and punitive portrayals of God in parts of the Hebrew scriptures (Deuteronomy 20:16–18, 1 Samuel 15:2–3 and Numbers 31:7–18, among others). The Gospels present Jesus telling his followers to love their enemies and imitate a God who is kind to the ungrateful and wicked (Luke 6:27–36; Matthew 5:43–48). The Hebrew scriptures also contain commands of destruction associated with Canaan (Deuteronomy 20:16–18; Joshua 6:17–21) and Amalek (1 Samuel 15:2–3).
Marcion concluded that these could not be revelations of the same deity. He distinguished the creator and lawgiver of the Jewish scriptures from the good God revealed through Jesus, rejected the Hebrew scriptures and accepted a restricted Christian collection consisting essentially of a version of Luke and ten Pauline letters.
His solution was condemned, but the problem he identified remains familiar. Christians who distinguish sharply between the violent God of some Old Testament passages and the God of love proclaimed by Jesus are confronting a recognisably similar problem even if they reject Marcion’s answer. Marcion’s collection also raised the question of which writings should count as Christian scripture and who had the authority to decide.
Valentinus, c. 100–160, and related movements produced other explanations. Their cosmologies contained aeons, Sophia, the Demiurge and archons, and placed Christ within a larger drama of divine emanation, ignorance and restoration. The term “Gnostic” covers movements which differed among themselves, but the surviving material shows Christian speculation moving far beyond disputes about sayings attributed to Jesus into attempts to explain the structure of reality itself.
Other possibilities remained. Some Jewish-Christian groups continued observance of Jewish law and understood Jesus in relatively human terms. Adoptionist tendencies treated him as a human being specially chosen or adopted by God. Such readings could appeal to passages such as the baptism scene, where the heavenly voice declares Jesus to be God’s Son (Mark 1:9–11), although such passages later received very different interpretations. Docetic tendencies questioned whether Christ’s humanity and suffering were fully real. Modalist theories later attempted to preserve divine unity by treating Father, Son and Spirit as manifestations of the one God.
The canonical writings themselves permit different emphases. Mark begins with the adult Jesus and his baptism (Mark 1:1–11). Matthew and Luke push his special status back to conception and birth (Matthew 1:18–25; Luke 1:26–35). John pushes it beyond birth altogether to a Logos existing “in the beginning” (John 1:1–14). Paul, writing earlier than all four Gospels, already attributes pre-existence and cosmic significance to Christ (Philippians 2:6–11; 1 Corinthians 8:6).
Irenaeus of Lyons, c. 130–202, writing around 180, opposed many of these alternative interpretations in Against Heresies. He defended the identity of the creator God of Israel with the Father proclaimed by Jesus, upheld apostolic succession and argued for the authority of four Gospels. Justin Martyr, c. 100–165, had written against heresies and specifically against Marcion, although those works have not survived, while Hippolytus of Rome, c. 170–235, later produced another large attack upon teachings regarded as heretical.
Irenaeus survives unusually well. Much of the literature he attacked does not. Some alternative Christian writings became known again only through discoveries such as Nag Hammadi. We often know defeated positions through people whose purpose was to refute them. The record inherited by later Christianity was already shaped by which communities survived, which writings continued to be copied and which authorities prevailed.
Some of the writings which did not enter the canon preserve a very different Jesus. The second-century Infancy Gospel of Thomas, for example, tells of the child Jesus making birds from clay and bringing them to life, but also cursing or striking down those who offend him. Such stories remind us how varied the traditions about Jesus could become before later Christianity settled upon a much narrower body of authoritative texts.
Institutional authority appeared early. Ignatius of Antioch, who died probably between 107 and 117, repeatedly refers to bishops, presbyters and deacons and urges Christians to remain united with their bishop. Polycarp of Smyrna, c. 69–155, was remembered as bishop of Smyrna, though the office was still much less developed than the later diocesan bishopric. By the early second century authority was already being attached to recognised offices rather than merely to informal groups of believers.
Churches communicated, exchanged letters and compared teaching. Like other movements centred on a charismatic teacher, early Christian communities offered mutual support as well as shared belief. Common worship, meals, expectations and stories reinforced the conviction that they belonged to a new order which had already begun in Jesus and which many expected soon to be completed. Disagreements produced excommunication, deposition and exclusion from communion. Paul himself advocates exclusion from the community in one disciplinary case (1 Corinthians 5:1–5, 11–13), while the Pastoral Epistles show developing concern with qualifications for bishops and deacons (1 Timothy 3:1–13; Titus 1:5–9). Organisation did not wait for Constantine.
Jesus’ call to “take up your cross and follow me” (Mark 8:34) is addressed to the disciple, not to an organisation. It calls for personal transformation, not the creation of an ecclesiastical hierarchy. To take a more recent example, Osho (1931–1990), an Indian spiritual teacher who attracted an international following, likewise centred his teaching on personal transformation rather than the creation of communes. Yet once an ashram existed, it provided community, identity, routine, shared language and mutual support. Those benefits could also create dependence, making separation from the group increasingly difficult. In both cases, organisation developed after followers had gathered around the teacher and his message.
Constantine, c. 272–337, changed the relationship between Christian institutions and political power. After 313, Christianity received legal toleration, confiscated property was restored, clergy acquired privileges, bishops gained public standing and imperial money supported churches. Bishops, councils and doctrinal disputes already existed; imperial patronage gave them resources and political consequences they had not previously possessed.
Christian unity now interested the emperor as well as the bishops. When the controversy associated with Arius, c. 256–336, spread through the eastern Church, Constantine summoned the Council of Nicaea in 325.
Arius did not teach that Jesus was merely an ordinary human being. He regarded the Son as pre-existent, exalted and the agent through whom creation occurred, but not eternal in precisely the same sense as the Father. The Son ultimately derived his existence from God.
Texts could be used on either side. Arius and those sympathetic to his position could appeal to passages which distinguish the Son from or subordinate him to the Father, such as “the Father is greater than I” (John 14:28). Opponents could appeal to passages identifying Christ much more closely with God, including John 1:1, John 10:30, Philippians 2:6 and Colossians 1:15–20.
Arius’s immediate ecclesiastical opponent was Alexander of Alexandria, died 328. The young Athanasius, c. 296–373, then a deacon, accompanied Alexander to Nicaea and succeeded him as bishop of Alexandria in 328. Athanasius became one of the most determined defenders of the Nicene position.
The Nicene dispute turned partly on the Greek word homoousios. The Son was declared to be “of one substance” with the Father. The creed described him as “God from God, Light from Light, true God from true God, begotten, not made”. The New Testament contains no such formulation. The language was devised to determine which interpretations of the inherited texts would be accepted.
Arius was condemned and exiled, but Nicaea did not produce immediate agreement. Constantine later permitted Arius to return from exile, while Athanasius was repeatedly expelled from Alexandria. Between 335 and 366, Athanasius endured five periods of exile. Imperial favour shifted, bishops formed rival alliances and alternative creedal formulas continued to circulate.
Athanasius tied the full divinity of Christ to salvation. If Christ were a creature, however exalted, he could not unite humanity with God or overcome the corruption and death from which humanity required deliverance. The nature of Christ was being reasoned out from assumptions about what salvation required. The discussion had moved far beyond the form in which Jesus’ teaching appears in the Synoptic Gospels.
Athanasius also appears in the history of the New Testament canon. In his Festal Letter of 367, he listed exactly the twenty-seven books now contained in the New Testament. Other Christian writings continued to circulate and be read, but this is the earliest surviving list identical to the modern New Testament canon.
The Council of Constantinople in 381, summoned under the emperor Theodosius I, consolidated the Nicene position and developed the Trinitarian settlement. The Son was fully divine and the Holy Spirit was also affirmed within the divine life.
Disagreement then concentrated increasingly upon the relationship between the divine and human in Christ. Nestorius, c. 386–451, patriarch of Constantinople, became involved in controversy over the unity of Christ and the title Theotokos — “God-bearer” — applied to Mary. He was condemned at the Council of Ephesus in 431.
The Council of Chalcedon in 451 defined Christ as one person in two natures, fully divine and fully human, “without confusion, change, division or separation”. Not all Christians accepted the Chalcedonian settlement, and divisions arising from these disputes remain among Christian churches.
A council could not make Christ divine by voting for his divinity. It could establish the formula which an institution would recognise as orthodox. Whether God became human in Jesus is a question of faith. That bishops debated the claim and adopted increasingly precise definitions of it belongs to the historical record.
More than four centuries separate the death of Jesus from Chalcedon. The subjects most prominent in the Synoptic Gospels are the Kingdom of God and the way human beings should treat one another. Jesus is presented as announcing the Kingdom (Mark 1:14–15; Luke 4:43) and linking fulfilment of the Law with love of God and neighbour (Mark 12:28–34). He tells his followers to forgive (Matthew 18:21–22), reconcile (Matthew 5:23–24), serve rather than dominate (Mark 10:42–45), care for those in need (Matthew 25:31–46) and refuse to make wealth their master (Matthew 6:24; Mark 10:21–25).
Within a few years of Jesus’ death, his followers were already proclaiming that God had raised him from the dead and had vindicated him as Messiah and Son. Paul inherited these beliefs rather than inventing them: he says explicitly that he had “received” the tradition of Christ’s death, burial, resurrection and appearances (1 Corinthians 15:3–5). Such claims were made in a world in which the boundary between human and divine was less rigid than it may seem today. The Greco-Roman world knew divine heroes, sons of gods, ruler cults and the deification of emperors, while Jewish tradition contained exalted heavenly beings, personified Wisdom, royal “sons of God” (Psalm 2:7) and the mysterious human-like figure of Daniel 7:13–14. Paul took an already exalted Jesus and developed a theology in which Christ’s death and resurrection became central to sin, salvation, the Law and the inclusion of the Gentiles (Romans 3:21–26; 6:1–11; Galatians 3:23–29). Marcion asked which God Christ had revealed. Valentinian Christians placed Christ within a new cosmology. Irenaeus defined acceptable scripture and apostolic teaching. Arius and Athanasius argued over whether the Son shared the Father’s eternal divinity. Nicaea and Constantinople defined the Son’s relationship to God. Chalcedon defined the relationship between divinity and humanity within Christ.
The change is also visible in the language attributed to Jesus himself. “Son of Man” occurs roughly eighty times in the four Gospels and overwhelmingly on Jesus’ lips. Examples appear throughout all four: Mark 2:10, 2:28, 8:31; Matthew 8:20, 12:40, 20:28; Luke 9:22, 12:40, 19:10; John 3:13–14, 6:53, 12:23. The phrase cannot simply be translated as “ordinary human being”; the imagery of Daniel 7:13–14 gives it possible apocalyptic significance. Yet the vocabulary repeatedly attributed to Jesus is different from the later creedal language of “God from God”, “of one substance with the Father” and “one person in two natures”.
“Son of God” is itself early and appears in the Gospels (Mark 1:11; 15:39; Matthew 16:16; John 20:31) as well as in Paul (Romans 1:3–4; Galatians 2:20). The development was not a simple replacement of “Son of Man” by “Son of God”. The change lay in what Son of God came to mean. A title capable of several meanings became, through centuries of argument, part of a precise doctrine of eternal divine nature.
Jesus’ teaching in the Synoptic Gospels repeatedly takes the form of an exhortation: forgive, reconcile, share, serve, love, seek the Kingdom. Paul makes the death and resurrection of Christ central to salvation. Later Christian theology develops doctrines of sin, redemption, incarnation, Trinity and the two natures of Christ. The question “How should we live?” remained within Christianity, while “What is Jesus?” became one of the questions by which orthodoxy itself was defined.
Other outcomes had once been possible. Had Marcion prevailed, Christianity might have rejected the Hebrew scriptures. Had Jewish-Christian forms remained dominant, Christianity might have retained a much closer relationship with Judaism. Had Valentinian Christianity prevailed, its account of God and the cosmos would have been different. Had Arius prevailed, Father and Son would not have been defined as sharing the same eternal substance. Without Constantine and his successors, theological disputes would still have continued, but bishops would not have possessed the same access to imperial authority.
The Christianity which emerged was therefore an historical construction in the literal sense that it was built over time: from memories, texts, interpretations, arguments, rival communities, episcopal organisation, councils and the survival of some traditions rather than others. The four Gospels themselves emerge from a period whose literary history is only partly visible to us; by the late second century they had become four authoritative accounts, and by the fourth century they stood within a developing canon whose boundaries were becoming increasingly fixed.
From those comparatively small beginnings grew a Church capable of defining the metaphysical nature of its founder and enforcing the resulting definitions across large parts of the Roman world.
The councils could decide what Christians were expected to affirm about Jesus. They could not ask Jesus of Nazareth whether they had understood him correctly.
Most forms of Christianity familiar today descend from the settlements reached through Nicaea, Constantinople and Chalcedon. Catholic, Orthodox, Anglican and most Protestant churches disagree about many things, but they inherited the same basic definition of Christ as fully divine and fully human within a Trinitarian understanding of God. Groups which reject parts of that inheritance still work by interpreting ancient texts whose authority and boundaries were themselves established through centuries of argument. No modern Christian tradition simply reproduces an untouched first-century faith. All stand somewhere within the long history by which Jesus was remembered, interpreted and defined.
Perhaps the most important thing is not to replace one certainty with another. The question is the path to the answer, and sometimes the path tells us more about ourselves — as individuals and as a species — than the answer itself.
Why are we so drawn to ideas of divine rescue, redemption and salvation?
Life is often confusing, threatening and disappointing, and that is precisely when the temptation to hand over responsibility to someone who claims to have the answer becomes strongest. According to the Church, the answer is Jesus, but in much of the teaching attributed to Jesus the emphasis falls on what each individual must do for themselves. When we hand over responsibility in this way, we make ourselves vulnerable, because we transfer part of our judgement and agency to another person, movement or institution. Yet the alternative is not despair but responsibility: to act, to change what can be changed, to endure what cannot, and to accept the consequences of our own choices. In the language attributed to Jesus, to take up our cross.
