The churches on the island of Crete need leadership, correction, and order. Establishing churches is Paul‘s forte, but Paul doesn’t sail to Crete to organize things. He already has someone on the island he can trust.
That man is Titus.
Titus is Paul’s partner in ministry (2 Co 8:23), a Gentile (Gal 2:3). Like Timothy, Titus is Paul’s child in the faith—he was introduced to Christ through Paul’s ministry (Ti 1:4).
