The first Christians continued “stedfastly in the apostle’s doctrine” (Acts 2:42). Jerusalem was filled with the “doctrine” of Christ (Acts 5:28).

Jesus said the Holy Spirit would come and “teach” the apostles “all things” (Jn. 14:26). Jewish officials did not want the apostles to “speak or teach” about Jesus (Acts 4:18). Christians did not “cease teaching” the Christian faith (Acts 5:42) and persistence allowed “much people to be taught” (Acts 11:26). Teaching was done in “every church” (1 Cor. 4:17) to assure doctrinal unity. Even “nature” can do some “teaching” (1 Cor. 11:14). Singing is designed to teach (Col. 3:16), and women are forbidden from “teaching” in the sense of usurping authority over men (1 Tim. 2:12).

The Old Testament is for our “learning” (Rom. 15:4). People may be carried about by every wind of “doctrine” (Eph. 4:14). Some teaching is contrary to sound “doctrine” (1 Tim. 1:10). There are the “doctrines” of devils (1 Tim. 4:1) as well as “good doctrine” (1 Tim. 4:6). Heed is to be given to “doctrine” (1 Tim. 4:13, 16). It is possible to “labor in doctrine” (1 Tim. 5:17).

Elders (1 Tim. 3:2) and the “Lord’s servant” (2 Tim. 2:24) are to be “apt to teach.” Part of this aptness seems to involve the refutation of religious error. Prior “to the NT, this word is attested only in Philo, who applies it not to persons but to virtue ‘acquired by teaching,’ etc., Mut 83” (ibid).
