it-1p.127Apostasy***An apostasy among professed Christians was foretold by the apostle Paul at 2 Thessalonians 2:3. He specifically mentioned certain apostates, such as Hymenaeus, Alexander, and Philetus. (1Ti 1:19, 20; 2Ti 2:16-19) Among the varied causes of apostasy set forth in apostolic warnings were: lack of faith (Heb 3:12), lack of endurance in the face of persecution (Heb 10:32-39), abandonment of right moral standards (2Pe 2:15-22), the heeding of the "counterfeit words" of false teachers and "misleading inspired utterances" (2Pe 2:1-3; 1Ti 4:1-3; 2Ti 2:16-19; compare Pr 11:9), and trying "to be declared righteous by means of law" (Ga 5:2-4). While still making profession of faith in God’s Word, apostates may forsake his service by treating lightly the preaching and teaching work that he assigned to followers of Jesus Christ. (Lu 6:46; Mt 24:14; 28:19, 20) They may also claim to serve God but reject his representatives, his visible organization, and then turn to ‘beating’ their former associates to hinder their work. (Jude 8, 11; Nu 16:19-21; Mt 24:45-51) Apostates often seek to make others their followers. (Ac 20:30; 2Pe 2:1, 3) Such ones willfully abandoning the Christian congregation thereby become part of the "antichrist." (1Jo 2:18, 19) As with the apostate Israelites, destruction is likewise foretold for apostates from the Christian congregation.—2Pe 2:1; Heb 6:4-8;
Think I found it. Idolatry might apply, but I guess "lack of faith" above qualifies. My bad.
