Titus
Apparently Paul introduced Christianity in Crete when he and Titus visited the island, after which he left Titus there to organize the converts. Paul sent the letter with Zenas and Apollos, who were on a journey that took them through Crete, to give Titus personal authorization and guidance in meeting opposition, instructions about faith and conduct, and warnings about false teachers. This is the last of the "Pastoral Epistles."
