Note 18 — Chapter IV
Reading edition
The Revisers as a rule render διδασκαλία by “doctrine,” as here, iv. 6, vi. 1, 3; 2 Tim. iv. 3; Tit. i. 9, ii. 1, 7, 10 (but not in iv. 13, 16, v. 17; 2 Tim. iii. 10, 16), while they render διδαχή by “teaching,” as 2 Tim. iv. 2; Tit. i. 9, and frequently in the Gospels. But διδασκαλία, as being closer to διδάσκαλος “a teacher,” is “teaching” rather than “doctrine,” and διδαχή is “doctrine” rather than “teaching.” See p. 238.
