1:15 This is a trustworthy saying: This expression occurs only in the letters to Timothy and Titus (1 Tim 3:1; 4:8-9; 2 Tim 2:11-13; Titus 3:4-8). These sayings are probably quotations from tradition that Paul has adapted to the current situation; here, in addition to the way the saying underscores the mercy shown to Paul, it probably corrects the false teachers. The emphasis of this saying falls on Christ’s entrance into history for the salvation of sinners, which was probably being marginalized by the false teachers, who emphasized law (1 Tim 1:7), special knowledge (6:20; cp. Titus 1:16), and stipulations such as those in 1 Tim 4:3 (cp. Col 2:16-23).
