Saint Augustine 
Confessions of St. Augustine 

The Confessions of St. Augustine is the collection of St. Augustine’s thirteen autobiographical books, each singly known as Confessions. In these books he details his sinful youth, his conversion to Christianity, and the regrets he thereafter lives with of his previous convictions and action. It is an incredibly important work, both as the theological study of his thought processes and development and also as a minute historical account from the 4th and 5th centuries.
