Jamieson, Fausset & Brown, on Titus 1:16

“They profess that they know God: but in their works they deny him; being abominable, and incredulous, and to every good work reprobate.”

“They profess--that is, make a profession acknowledging God. He does not deny their theoretical knowledge of God, but that they practically know Him. deny him--the opposite of the previous "profess" or "confess" Him (Ti1 5:8; Ti2 2:12; Ti2 3:5). abominable--themselves, though laying so much stress on the contracting of abomination from outward things (compare Lev 11:10-13; Rom 2:22). disobedient--to God (Tit 3:3; Eph 2:2; Eph 5:6). reprobate--rejected as worthless when tested (see on Rom 1:28; Co1 9:27; Ti2 3:8). Next: Titus Chapter 2”
