Albert Barnes Commentary Titus 2:7

"in all things showing thyself an ensample of good works; in thy doctrine [showing] uncorruptness, gravity," — Titus 2:7 (ASV)

In all things showing yourself a pattern of good works. Not merely teaching others, but showing them by example how they ought to live. On the word rendered pattern (tupon, type), see Hebrews 8:6; 1 Corinthians 10:6; Philippians 3:17.

In doctrine. In your manner of teaching. See 1 Timothy 4:16.

Showing uncorruptness. The word used here does not occur elsewhere in the New Testament. It means, here, the same as purity—that which is not erroneous, and which does not tend to corrupt or vitiate the morals of others, or to endanger their salvation. Everything in his teaching was to be such as to make them purer and better.

Gravity. See this word explained in 1 Timothy 2:2, where it is rendered honesty. Compare 1 Timothy 3:4, where it is rendered gravity. It does not occur elsewhere. See the use of the adjective, however, in Philippians 4:8; 1 Timothy 3:8, 11; Titus 2:2.

The word properly means venerableness; then, whatever will ensure respect in character, opinions, and deportment. The sense here is that the manner in which a preacher delivers his message should be such as to command respect. He should evince good sense, undoubted piety, an acquaintance with his subject, simplicity, seriousness, and earnestness, in his manner.

Sincerity. See this word (aphtharsia) explained in Ephesians 6:24.

It is rendered immortality in Romans 2:7; 2 Timothy 1:10; incorruption, in 1 Corinthians 15:42, 50, 53, 54; and sincerity, in Ephesians 6:24 and in the passage before us. It does not occur elsewhere in the New Testament. It means incorruption, incapacity of decay; and, therefore, would be here synonymous with purity. It should be said, however, that it is wanting in many manuscripts, and is rejected in the later editions of the New Testament by Wetstein, Tittman, and Hahn.
