I'll start with 
 Augustine of Hippo
He wrote an outline of history and a theory of government, "The City of God", where he rebutted some of the remaining pagans who argued that the Western Roman Empire fell because of disregarding the worship of the deities of Rome's old-time religion.
				
			He then went on to become a noted Xian theologian. He wrote an autobiography, "Confessions", and he moaned and groaned at length about what a terrible sin he once committed: as a little boy, he and some other little boys stole some pears. He also wrote that babies are terrible sinners, guilty of gluttony and jealousy and the like.In late August of 386,[81] at the age of 31, having heard of Ponticianus's and his friends' first reading of the life of Saint Anthony of the Desert, Augustine converted to Christianity. As Augustine later told it, his conversion was prompted by hearing a child's voice say "take up and read" (Latin: tolle, lege). Resorting to the Sortes Sanctorum, he opened the Bible at random and read Romans 13: 13-14: Not in rioting and drunkenness, not in chambering and wantonness, not in strife and envying, but put on the Lord Jesus Christ, and make no provision for the flesh to fulfill the lusts thereof.[82]
