Paul begins his letter to Titus with a needed explanation. The defense of his apostleship is seen in various places throughout scripture. “As…one born out of due time” (1 Corinthians 15:8) his apostleship was questioned by some. However, Titus was aware of the legitimacy of his office, for Paul described him as “a true son in our common faith.” Ergo, we find the practicality of this letter not only for Titus, but for others as well. In addition, this salutation defended Titus against any opposition to his authority in the Gospel on the island of Crete.
Paul’s apostleship was in agreement with the truth. He was carrying about a work given him by God. His letter, and ministry as an apostle, was “in hope of eternal life.” Although Paul currently had life in Christ, as does any saint, the life could still be forfeited (cf. Hebrews 12:14-17). His attitude was always to press on toward the goal of eternal life (cf. Philippians 3:12-16). However, the surety of such was in the promise of God to deliver eternal life – “God, who cannot lie, promised.” This promise is revealed by God in His Holy Word. The preaching of this message was entrusted to Paul as an apostle.
Paul ends his salutation with an intimate phrase – “To Titus, a true son in our common faith.” Like Timothy, Titus was converted by Paul. This relationship obviously grew into a close bond. Paul then shows his concern and confidence in Titus that he continually receive “grace, mercy, and peace from God.”
