The Holy Spirit: From Wind to Fiction

Excerpt:
The “Holy Spirit” of Christianity is not a continuation of the Hebrew ruach but a mistranslation that became a doctrine. What began as the roar of wind in the Old Testament turned into an abstraction in Luke–Acts — and finally into a third “person” of the Trinity.

In the Hebrew Bible, the word most often translated as “Spirit” is ruach. It is an earthy, physical word: it means wind, breath, or a gust of air. When Genesis opens, “the ruach Elohim was hovering over the waters” (Gen. 1:2), the image is not of a ghostly presence but of a mighty wind sweeping over the deep — or, as the Italian translator and polemical commentator Mauro Biglino argues in his literal reading of Hebrew, perhaps something even more concrete than mere wind. When God animates the first human being, he “breathed (ruach) into his nostrils the breath of life” (Gen. 2:7). The same word is used for the Spirit that comes upon Israel’s judges and kings, a rush of energy that empowers Gideon (Judg. 6:34), Saul (1 Sam. 10:10), or David (1 Sam. 16:13). Ezekiel imagines the dry bones of Israel coming to life when God declares: “I will put my ruach within you, and you shall live” (Ezek. 37:14). Joel’s promise that God will “pour out my ruach on all flesh” (Joel 2:28) makes sense in this concrete register: God’s own breath, poured out like a rushing gale.

Biblical Hebrew is built around roots that allow a cluster of meanings to grow from the same three consonants. Ruach can therefore mean a gust of wind, the breath of life, or a person’s mood or disposition. In Hebrew thought these meanings shade into one another. Biglino presses the point further, insisting that ruach is not “spirit” in any metaphysical sense at all, but strictly something physical — a rush of air, a blast, a noise. Even if one does not follow him to his more speculative conclusions, he is right to remind us how concrete the word is in its original setting.

But when the Septuagint translators rendered ruach as pneuma, they imported the baggage of Greek philosophy, where pneuma already meant not only air and breath but also the animating principle of life and even the rational soul. What was once a sensory experience — the rush of God’s wind — became an abstract concept. As Biglino would point out, this is precisely where the misunderstanding begins: a mistranslation that reinterprets a physical phenomenon as an invisible “Spirit.”

This helps to explain the peculiar character of Luke–Acts, the New Testament’s most Spirit-saturated work. Luke’s Gospel presents the Spirit as a guiding presence throughout Jesus’ life: “The Holy Spirit descended in bodily form like a dove upon him” (Luke 3:22); Jesus declares, quoting Isaiah, “The Spirit of the Lord is upon me, because he has anointed me” (Luke 4:18). In Acts, the Spirit becomes the driving force of the church’s expansion. At Pentecost, “suddenly there came from heaven a sound like a mighty rushing wind … and they were all filled with the Holy Spirit and began to speak in other tongues” (Acts 2:2–4). When Peter preaches to Cornelius’ household, “the Holy Spirit fell on all who heard the word” (Acts 10:44). And when Paul laid hands on new believers at Ephesus, “the Holy Spirit came on them, and they began speaking in tongues and prophesying” (Acts 19:6).

Again and again the Spirit descends, fills, falls — always as proof that God is at work, but never described in substance.

In Acts, the Holy Spirit is everywhere as proof — yet nowhere in substance. It validates Paul’s mission, but remains undefined.

Acts also functions as propaganda in another way: it gives us the only continuous narrative of Paul’s journeys. Yet whether those journeys took place as described is uncertain. Paul’s own letters sometimes diverge from Acts’ timeline; his speeches in Acts sound more like Luke’s theology than Paul’s; and the sharp edges of Paul the polemicist are smoothed away in favour of a unifying figure. Just as Acts gives us a Holy Spirit everywhere present but undefined, so it gives us a Paul whose history may be more crafted than remembered.

Acts goes only the shortest way toward giving us anything like a coherent or complete theology. It tells stories of the Spirit descending, of crowds converted, of apostles emboldened — but it never pauses to explain what the Spirit is, how it relates to God, or what role it plays in the life of believers. The same is true of atonement: Jesus’ death and resurrection are proclaimed as the heart of God’s plan, and forgiveness is offered through repentance and baptism, but Acts never explains how the cross brings salvation. There is no doctrine of substitution, no theory of satisfaction, no worked-out vision of justification. Its interest lies in narrative and persuasion, not in system.

This vagueness proved decisive for later theology. The Spirit was too prominent in Acts to be ignored, yet too ill-defined to be understood. Early thinkers like Irenaeus described the Spirit as one of God’s “two hands.” Tertullian, writing around 200 CE, coined the term trinitas to capture the relationship of Father, Son, and Spirit. By 381 the Nicene Creed declared belief “in the Holy Spirit, the Lord, the giver of life, who with the Father and the Son is worshipped and glorified.” What had begun as a rush of wind in the Hebrew Bible, and been reinterpreted as a vague divine agent in Luke–Acts, eventually crystallised into the third person of the Trinity.

The question remains: does this “Holy Spirit” correspond to any real entity? Or is it the by-product of translation and narrative necessity — proof in the text, but substance nowhere to be found? What began as a blast of air was translated into a ghost. On that mistranslation, an entire doctrine was built. Whether that doctrine stands as revelation or invention is left for the reader to judge.

Whatever doubts we may cast on Acts as history, one fact cannot be denied: Christianity did take off with remarkable speed after Jesus’ death. Within a generation, communities were established across the eastern Mediterranean, from Jerusalem and Antioch to Corinth and Rome. Paul’s own letters, written barely twenty years after the crucifixion, testify to an already vibrant and argumentative network of believers. Acts may embroider the story, but it reflects a real phenomenon: a small Jewish sect that grew, against the odds, into a movement that reshaped the ancient world.
