The book of Titus is a Pastoral Epistle (letter from Paul to a church leader). The author is Paul who wrote it approximately 66 A.D. Key personalities include Paul and Titus. It was written to guide Titus, a Greek believer, in his leadership of the churches on the island of Crete, "For this reason I left you in Crete, that you would set in order what remains and appoint elders in every city as I directed you" (1:5). As was the case with the letter of 1st Timothy, Paul writes to encourage and guide young pastors in dealing with opposition from both false teachers and the sinful nature of men.
