How Christianity Absorbed, Renamed, and Then Banned the World It Was Built On

How Christianity Absorbed, Renamed, and Then Banned the World It Was Built On

Banked research — the absorption mechanism in the Church Fathers' own words

There is a sentence the early Church used for two thousand years whenever someone noticed how familiar Christianity looked: everyone before me was just predicting me. It is the exact move of a student caught copying who insists the original author was merely anticipating his work. And the remarkable thing is that the Church Fathers said it openly, in writing, in language we can still read.

"It was always here"

Augustine, writing around 427 AD in his Retractationes, put it most plainly:

"The identical thing that we now call the Christian religion existed among the ancients and has not been lacking from the beginnings of the human race until the coming of Christ in the flesh, from which moment on the true religion, which already existed, began to be called Christian."

In the Roman world, age equaled truth and novelty was suspect. Pagan critics attacked Christianity as a brand-new invention. Augustine's counter was audacious: Christianity is not new — it is the oldest thing there is, and everything that resembles it came before merely anticipated it.

Logos Spermatikos: the seed of reason

Justin Martyr (c. 150 AD) argued that Greek philosophers like Socrates and Plato spoke truth because they carried a fragment of the divine Word — the logos spermatikos, the "seed-bearing reason." To become Christian, in this framing, was not to abandon ancient wisdom but to fully absorb it.

Clement of Alexandria, a few decades later, extended it: God gave philosophy to the Greeks to prepare their minds for Christ, just as he gave the Law to the Hebrews. "Philosophy was a preparation, paving the way for Christ... The way of truth is a perennial river, streams flow from all sides."

The spoils of Egypt

Origen, working in the same Egyptian city around 230 AD, dropped the metaphor of preparation for the metaphor of plunder. In his Letter to Gregory he told Christians to do what the Israelites did when they fled Egypt with stolen Egyptian gold and melted it down to build the Ark:

"You may take from the philosophy of the Greeks what can serve you as a preparation for Christianity... so that you may do what the children of Israel did, who brought out of Egypt things which they made into the furniture of the Holy of Holies."

Greek philosophy was the Egyptian gold. It did not belong to the pagans; it belonged to God, and Christians had every right to take it back. Augustine repeated the argument in De Doctrina Christiana: the pagans are "unjust possessors" of a truth that was never theirs to hold.

Diabolical mimicry: the devil plagiarized us in advance

The pagan critics noticed the copying first. Celsus, writing The True Word around 177 AD, accused Christians of stitching their story together from older myths — the virgin birth from Danae and Antiope, the death-and-resurrection from Dionysus, the bread-and-wine meal from Mithras, all of them older. (We only know Celsus's arguments because Origen quoted them line by line to refute them in Contra Celsum — the Church burned the original. You burn what threatens you.)

The Christian apologists could not deny the resemblances. So they invented one of the strangest defenses in the history of religion: retroactive demonic plagiarism. Justin Martyr argued that demons had read the Hebrew prophecies in advance, foreseen the coming of Christ, and deliberately manufactured counterfeit pagan religions — Dionysus, Mithras — before Christ arrived, specifically to confuse humanity when the real thing showed up.

"The wicked devils have imitated [the Eucharist]." — Justin Martyr, First Apology, Ch. 66

The similarities were real. The explanation was that the devil got there first.

Absorb, then ban

Here is the part that completes the pattern. While Christianity was a persecuted minority that needed to win pagan converts, absorption was policy — build the intellectual bridges, plunder the gold, claim the philosophy. Augustine built his entire theology of heaven and the soul on Plato.

But absorption was always contested. Tertullian (c. 155–220 AD) fought it bitterly:

"What indeed has Athens to do with Jerusalem? What concord is there between the Academy and the Church? ... Away with all attempts to produce a mottled Christianity of Stoic, Platonic, and dialectic composition!"

His argument was sharp: if you need Greek philosophy to explain the Gospel, you are admitting the Gospel is insufficient on its own.

And once Christianity held total imperial power, the need for bridges vanished. The philosophical schools were recategorized as hotbeds of stubborn paganism. In 529 AD, the Emperor Justinian closed the Neoplatonic Academy in Athens — the school Plato had founded nearly 900 years earlier — banned pagans from teaching, and cut public funding, scattering the last pagan philosophers out of the empire.

The arc is the whole thesis in miniature: take the meat, keep the shell, then outlaw the kitchen. They plundered the philosophy to build the cathedral, then closed the schools that produced it.

What survives when the text is burned

The Mithras case shows what "erasure" actually looks like in the record. Skeptics correctly point out that no surviving text says Mithras's followers celebrated his birthday on December 25 — they simply joined the empire-wide solar festival, Natalis Invicti, the Birth of the Unconquered. But almost nothing of Mithraic theology survives in writing at all, because it was a secret mystery cult that wrote little down, and because Theodosius's decrees (c. 380–392 AD) outlawed the worship and seized or destroyed the temples.

What survives is buried — literally. Over 400 mithraea and 1,000+ monuments have been found from Scotland to Palestine. The temples were built underground, in artificial caves, to mimic the cave where Mithras killed the cosmic bull. When Christians took over, they built their churches directly on top. At the Basilica of San Clemente in Rome you can descend from a 12th-century church, into a 4th-century church beneath it, into a perfectly preserved 2nd-century Mithraic temple beneath that, altar intact. Everywhere, the same image: the Tauroctony, Mithras plunging the dagger into the bull's neck.

The absence of text is not evidence of absence. It is evidence of a fire. The temple is still in the basement.

How the date was overwritten

John Chrysostom, preaching in Antioch around 386 AD, admitted the strategy for Christmas with no embarrassment at all:

"They call it the 'Birthday of the Unconquered.' Who indeed is so unconquered as Our Lord? Or, if they say that it is the birthday of the Sun, He is the Sun of Righteousness."

And the overwrite of space matched the overwrite of time. Pope Boniface IV consecrated the Pantheon — "temple of all the gods" — as a church in 609 AD, hauling in twenty-eight cartloads of martyrs' bones. Pope Gregory the Great had written the policy in 601: don't destroy the temples, just destroy the idols inside them, sprinkle holy water, set up altars. Keep the building. Change what it means. The people, seeing their familiar sacred space preserved, will follow.

Keep the building. Change what it means. That is the whole story, in a sentence a pope wrote down.
