If anyone teaches a different doctrine, and doesn't consent to sound words, the words of our Lord Jesus Christ, and to the doctrine which is according to godliness,
and consent not to wholesome words: The word "wholesome" (hugiainousin) conveys the idea of sound expression and thought. (See Luke 5:31, 1 Timothy 1:10, Titus 1:13, and 3 John 1:2.) Vine explains that "while it signifies the essential character of the doctrines of the faith and of the words of God, it also intimates their healthful effect upon the believer in maintaining his soul in holiness and purity" (19). (Other teaching regarding sound doctrine can be found in 2 Timothy 1:13; 2 Timothy 4:3; Titus 1:9; Titus 2:1.)
