His Confessions, written when he was in his forties, recount how, slowly and painfully, he came to turn away from his youthful ideas and licentious lifestyle, to become instead a staunch advocate of Christianity and one of its most influential thinkers.A remarkably honest and revealing spiritual autobiography, the Confessions also address fundamental issues of Christian doctrine, and many of the prayers and meditations it includes are still an integral part of the practice of Christianity today.
