S1E1 - What the Floor Showed Me

It began with a crack in the floor. Standing inside the ancient Basilica of Aquileia in northern Italy, I looked down at a mosaic older than the church above it — a mosaic that did not match the story I had been told. No cross. No martyrdom. No bishop. No altar. It was Christian, but it was Christian in a way later Christianity no longer resembled. That dissonance is where this series begins. This episode introduces the central claim of Christianity Unfolded: Christianity did not begin as one thing. It began as many. Only one version survived. We trace three discoveries that shaped that conclusion:    • Nag Hammadi (1945) — thirteen leather-bound books pulled from an Egyptian jar, preserving Christianities that vanished    • Paul versus Acts — a movement remembered as unified by Acts, but Paul's own letters preserve conflict, rivalry, and disagreement    • Post-70 Judaism — when the Temple fell, two religions emerged from one trauma, neither predetermined We then turn to power. Constantine did not adopt Christianity because of its theology. He adopted it because it functioned. Legalization in 313 did not create orthodoxy — it created the conditions under which one version could dominate. By 380, Nicene Christianity was the empire's only legal religion. Diversity passed through a narrow historical bottleneck. What survived did so through alignment with power. Christianity was a forest, not a single tree. Most of the forest was cleared. Not from tradition. From evidence.
