Confessions is an autobiography written by Augustine of Hippo in 397-398 CE about his struggle with sin and his conversion to Christianity. The early parts of the book describe Augustine's struggle with selfishness, peer pressure, lust, sin and the fallacious teachings of Manichaeanism. Under the influence St. Ambrose, Augustine abandons Manichaenism and eventually finds enlightenment and relief from suffering in Christianity. In the end of the book, Augustine expounds upon the meaning of time, memory, Genesis and the Holy Trinity.
