From Jerusalem to Rome: How a Jewish Movement Became a World Religion
Paul did not create Christianity out of nothing. When he first appears in the record, he is already contending with an existing Jerusalem-based messianic movement. Acts itself provides evidence for this: after the death of Stephen, Saul is said to persecute “the church” in Jerusalem (Acts 8:1–3), and later Jerusalem appears as the movement’s central authority under leaders including James (Acts 15:1–29; 21:17–18). Whatever precise form this earliest community first took, it seems to have arisen within the tense political and religious atmosphere of Roman-occupied Judaea, where messianic expectation, sectarian conflict, and resistance to Roman rule were never far from the surface.
If that is so, then Christianity did not begin as a free-floating metaphysical system. It began, or at least first cohered, within the tense atmosphere of Roman-occupied Judaea: an atmosphere of messianic hope, apocalyptic expectation, religious controversy, and political unease. The later destruction of Jerusalem and the upheavals of the Jewish wars help explain why we know so little about that original milieu and why later, non-Jerusalem forms of Christianity came to dominate the surviving record. Britannica’s overview of early Christianity places its roots squarely in the Jewish world of Roman Palestine. (Encyclopedia Britannica)
The earliest persecution of this movement also seems to have come chiefly from within Judaism rather than from Rome as such. Paul is described in modern historical summaries as a persecutor of the primitive church before his change of allegiance. That points not to a Roman state campaign in the first instance, but to a conflict within the Jewish world under Roman occupation. Paul may have possessed Roman citizenship according to Acts, but the evidence does not justify saying that he was working as a Roman agent. It is safer to say that he acted as a zealous opponent of the movement from within the religious framework of his time. (Encyclopedia Britannica)
The canonical gospels should therefore be read not as eyewitness transcripts but as late first-century literary-theological constructions. Mark is generally regarded as the earliest gospel, written around the time of the destruction of Jerusalem. Matthew was composed after 70 CE and shows dependence on Mark. John is later still and more theologically distinctive. Whatever earlier traditions they may preserve, these texts are not stenographic reports from the scene. They are shaped documents, formed by memory, scriptural interpretation, communal need, and theological reflection. (Encyclopedia Britannica)
That does not make the gospels worthless. It simply means they belong to a process of composition and interpretation rather than to journalism in the modern sense. The Jesus they present is already interpreted, arranged, and narrated for communities living decades after the events. Their value lies partly in what they may preserve from earlier tradition, and partly in what they reveal about the beliefs and needs of the communities that produced and transmitted them. (Encyclopedia Britannica)
Pauline Christianity marks a further and decisive stage in that development. Paul’s letters are the earliest surviving Christian writings. Britannica describes them as containing reliable but meagre evidence and as preserving early tradition about Jesus’ death, burial, resurrection, and appearances. It also emphasizes Paul’s crucial role in developing Christianity away from its parent religion of Judaism. This matters because Paul does not merely preserve a local Jewish memory. He universalizes the movement and gives it a wider theological horizon. (Encyclopedia Britannica)
In Paul, the centre of gravity shifts away from the remembered sayings and deeds of an earthly teacher and toward Christ as a cosmic figure whose death and resurrection have universal significance. That is one reason Paul proved so foundational. He did not simply guard an original Jerusalem inheritance. He reinterpreted it in a form that could travel. His theology opened the movement to the Greek-speaking and Roman worlds and helped detach it from its original local and Jewish setting. (Encyclopedia Britannica)
That point also helps to clarify the relation between Paul and Gnosticism. Paul should not be confused with the later Gnostics. The main body of Gnostic teaching belongs to the second century CE and after, and its more elaborate cosmologies stand at some distance from the comparatively direct and practical theology of Paul. Nor should Paul be treated as the originator of Gnostic thought, since many of the religious currents later absorbed into Gnosticism were already present in the wider Hellenistic world before his time. What can reasonably be said is something more limited. Paul’s Christianity seems already to have been complete in its essentials: a full vision of revelation, redemption, rebirth, and union with Christ, powerful enough to satisfy his own spiritual and psychological needs. Yet later Gnostic thinkers were able to seize upon certain Pauline themes and adapt them to their own purposes. His language of revelation, spiritual transformation, hidden wisdom, and the cosmic significance of birth, death, and resurrection — with resurrection itself presented as the pattern of rebirth for all who entered into Christ — offered material that could be taken up into far more speculative systems. In this respect, Paul’s teaching still links back to Jesus’ call to metanoia, to inner change and reorientation, though it does so in a more cosmic and mythologically charged form. He was not a Gnostic outright; but in certain respects his thought proved capable of later Gnostic appropriation.
Second-century Gnosticism did not arise in a vacuum either. In its Christian forms, it seems to have drawn not only on emerging Christian theology, but also on older religious currents already present in the Hellenistic and Roman worlds: dualism, esoteric salvation, cosmic ascent, initiatory practice, and the language of hidden knowledge. In that sense, Christian Gnosticism is best understood not as a wholly novel corruption of Christianity, but as a hybrid development, shaped by Christianity while also fed by religious patterns that had predated it by centuries.
As Christianity moved through the Greek-speaking and Roman worlds, it entered a religious environment already rich in initiation rites, sacred meals, fasting, purification, rebirth symbolism, and salvation language. Britannica notes that the mystery religions and Christianity shared many outward features, including preparation before initiation, fasting, baptismal forms, banquets, vigils, pilgrimages, and new names for initiates. That does not prove that Christianity was simply copied from Mithraism or any other single cult. It does, however, make it highly plausible that Christianity increasingly absorbed and re-expressed itself through forms already intelligible to the wider Mediterranean world. (Encyclopedia Britannica)
This is the more serious way to discuss pagan parallels. The crude claim that every feature of Christianity can be matched neatly to Horus, Mithras, or some other deity is usually too blunt to persuade. But the broader claim, that religions expand by adaptation, translation, and symbolic enrichment, is historically far more plausible. Christianity did not grow in a vacuum. It spread through a world already full of ritual meals, cosmic symbolism, purification rites, and languages of salvation. The process need not be reduced to direct borrowing; accretion and reinterpretation are enough to explain much. (Encyclopedia Britannica)
This process becomes still clearer in the long emergence of orthodoxy. The church that became orthodox did indeed select, privilege, and organize certain texts and narratives while excluding others. Canon formation was gradual and contested, not a single act of invention. Standard historical summaries describe the New Testament canon as the outcome of a long process of recognition and consolidation rather than a sudden decree. The effect was to stabilize one developing synthesis of belief and practice over against alternatives. (Encyclopedia Britannica)
This is why it is misleading to imagine that one council suddenly created Christianity from scratch. The Council of Nicaea in 325 was historically important, but its main business was the Arian controversy. Britannica’s material on Arianism and Nicaea treats the council primarily as a response to the dispute over Christ’s status and relation to God, not as the moment when the New Testament canon was invented by imperial fiat. The larger point, however, still stands: the institutional church increasingly defined orthodoxy, drew boundaries, and consolidated one synthesis of belief and practice over against rivals. (Encyclopedia Britannica)
By the time one reaches the developed forms of Roman Catholic Christianity, the process of accretion is difficult to miss. One sees a religion of sacraments, liturgical calendar, sacred hierarchy, feast days, visual symbolism, saints, cosmic drama, and elaborate mediation. One need not assume cynical fabrication to say that this stands at some distance from a small Jewish movement in Jerusalem under James. It is better understood as a historical synthesis: an original nucleus gradually clothed in forms suited to the late antique and medieval worlds. The Roman Church preserved much, organized much, and amplified much. It did not simply hand down an untouched primitive simplicity. (Encyclopedia Britannica)
None of this requires the cruder claim that everything was fabricated wholesale at a late date. Nor does it require saying that Paul was simply preaching Gnosticism before its time, or that Christianity was nothing but one more mystery religion under Jewish names. The stronger historical thesis is subtler than that. An early Jewish movement associated with James was opposed by sections of the Jerusalem religious establishment, later universalized by Paul, narrativized by the evangelists, symbolically enriched in the Greco-Roman world, and finally organized into orthodoxy by the institutional church. (Encyclopedia Britannica)
Yet the stripping away of later accretions need not end in mere negation. If one asks what may still remain at the core, another possibility appears. We seem to be born with an inbuilt orientation towards the good, though it is soon obscured by contact with the world. Much of Jesus’ teaching, as far as we have it, can be understood as an appeal to recover that original moral impulse through inner re-alignment rather than external conformity. On this reading, metanoia is not simply repentance in the narrow sense, still less submission to dogma, but a return to the deepest and soundest part of oneself: a clearing away of illusion, vanity, fear, and social corruption so that the original moral centre may speak again. At the end of the day, moral authority cannot simply be outsourced to dogma. Traditions may guide, warn, and illuminate, but the final court of appeal is the awakened conscience of the individual.
Seen in that light, Christianity becomes neither sheer fraud nor simple transcript of origins. It becomes what many great religions are: a layered historical formation in which memory, interpretation, politics, ritual, and imagination all play their part. The earliest nucleus may have been smaller, more Jewish, and more politically or morally focused than later orthodoxy allowed. But that nucleus was not merely lost. It was transformed, enlarged, and embedded in one of the most powerful religious syntheses in history. (Encyclopedia Britannica)
As the paraphernalia of traditional Christianity loses significance, there is a growing need to return to the original teachings of Jesus rather than the catechism constructed around him. For the heart of that teaching is not the humiliation of man as merely fallen and corrupt, but the call to life: “I have come that they should have life, and have it abundantly.” The promise is not that we are worthless sinners rescued only by submission, but that beneath all distortion there remains in us a capacity for re-alignment with the good. “Hear, O Israel … thou shalt love …” — this is the deeper note. Religion begins there, not in abasement, but in right orientation: in the recovery of that obscured but native responsiveness to truth, love, and moral being. If the old dogmatic structures are fading, that need not be a loss. It may be the necessary clearing away of what has hidden the original promise.
When I was at school, it was customary each day to listen to a reading from the Bible. Those readings were not presented to us as mythology, cosmology, or theological system, but as moral stories from which we were meant to learn. They formed part of moral education rather than catechetical indoctrination. Whatever later Christianity may have built around Jesus, that older school practice at least preserved an instinct that the heart of the tradition lay in ethical teaching, character, and the shaping of conscience.
Perhaps these reflections also explain my own aversion to traditional Christian teaching. What I recoil from is not the moral seriousness of the Bible, nor the call to inner change that seems to stand at the heart of Jesus’ teaching, but the later dogmatic framework in which Christianity came to be presented: as catechism rather than awakening, as assent rather than understanding, as guilt rather than re-alignment. Perhaps that is why I still feel that whatever is most living in the tradition lies in its ethical and formative power rather than in the doctrinal structure later built around it.
