Introduction to Titus

This epistle chiefly contains directions to Titus concerning the elders of the Church, and the manner in which he should give instruction; and the latter part tells him to urge obedience to magistrates, to enforce good works, avoid foolish questions, and shun heresies. The instructions the apostle gave are all plain and simple. The Christian religion was not formed to answer worldly or selfish views, but it is the wisdom of God and the power of God.
