The Augustinian doctrine of original sin requires a historical Fall: a first human being, created in a state of perfection, who chose evil and transmitted guilt and a damaged nature to all descendants. This assumes a static cosmos — a state of original perfection from which history is a decline. Evolution makes this assumption impossible: there was no first human in any meaningful biological sense, no state of original perfection, and the process of life has always involved suffering, death, and predation, long before any human choice.
Teilhard's alternative reconceives evil not as the consequence of a historical act but as the structural shadow of an evolving universe. A world that is becoming rather than complete will inevitably contain error, waste, suffering, and failure — not because God wills these but because a universe moving toward greater complexity and consciousness must pass through stages of imperfection. Evil is the price of creation, the disorder intrinsic to a universe that has not yet arrived at its term. This does not eliminate the reality of moral evil but reframes it within a cosmological context.
If evil is the shadow of becoming rather than the result of a Fall, redemption cannot mean restoring a lost perfection but must mean the transformation and final integration of a creation still in process. Christ's redemption is not the cancellation of a debt incurred by Adam but the energising of creation's movement toward the Omega Point — the injection of love and consciousness into an evolving universe that needs both to reach its term. Teilhard acknowledges that this reconstruction is incomplete and that the Church's magisterium has not accepted it, but he regards it as the necessary starting point for a theology adequate to the scientific account of the world.
Teilhard's essays on original sin, written between 1920 and 1950, are collected in Christianity and Evolution (1971). They were never approved for publication in his lifetime and remain among the most theologically controversial elements of his thought.
