Augustine of Hippo · Theology
Augustine’s doctrine of original sin and grace grew from a problem he could not escape: why he could clearly see the good and still be unable to will it. His answer reshaped Western Christianity - and provoked its first great theological war.
Long before he was a bishop, Augustine faced a problem that philosophy could not solve for him. He had become intellectually convinced that he should change his life - and found he simply could not make himself want to enough to do it. He knew the good, approved the good, and remained chained to the habits he despised. This experience - of a will that fails to obey its own clearest judgement - became the seed of his whole theology of sin and grace. The ancient philosophers had mostly assumed that to know the good is to do it, and that wrongdoing is ignorance. Augustine, looking honestly at himself, concluded they were wrong. The trouble was not in his knowledge but in his will.
Why is the will divided in the first place? Augustine’s answer is the doctrine of original sin. He held that the whole human race, descended from Adam, inherits not just mortality but a disordered nature - a will bent in on itself, no longer able by its own power to love God above all. We are born, he says, with our loves already misaligned. This is not a charge that babies commit crimes; it is the claim that we all enter a condition we did not choose, in which doing the genuine good is no longer simply within our reach. The evidence, for Augustine, is everywhere: the universality of selfishness, the ease of cruelty, the difficulty of real virtue, and - most personally - his own years of seeing the good and failing to will it.
For Augustine, grace is not God rewarding our good efforts; it is God acting first, before and beneath any effort of ours, to repair a will too damaged to repair itself. He loved Paul’s question: ‘What do you have that you did not receive?’ Even our faith, even our first feeble desire to turn around, is itself given. This is the doctrine that makes Augustine the great theologian of dependence: the human being is not a self-made moral hero but a patient being healed. Critics across the centuries have found this either the most liberating truth in Christianity - you do not have to save yourself - or its most troubling, since it seems to make our salvation depend on a gift we cannot command. Augustine embraced both edges.
This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.
You learned that Augustine explained moral failure by a will divided against itself, healed only by grace. Reconstruct his argument, and state his opponent Pelagius’s objection, in your own words.
