Confessional faith in the Pastoral Epistles
‘The later letters in the New Testament to Timothy and Titus, in addition to their continuing use of these dynamic definitions of faith, distinguish true faith from false faith by making the content of faith confessional (2 Tim. 4:3; Titus 1:9). Sound doctrine becomes the basis for right teaching (Titus 2:1) and right living (2 Tim. 3:15). Paul’s words to Timothy when faced with the prospect of death—“I have kept the faith” (2 Tim. 4:7)—can be a witness to both the dynamic quality of his life in Christ and the correctness of his understanding.’
