Heresy
Heresy falls into three categories: heresies of the nature of Jesus Christ; heresies of the Trinity; and heresies of the nature of salvation.
English Standard Version (ESV); Lexham English Bible (LEB): Revised Version (RV); American Standard Version (ASV)
“…for there must be factions (heresies) among you in order that those who are genuine among you may be recognized.” 1 Corinthians 11:19 (ESV)
“But this I confess to you, that according to the Way, which they call a sect, I worship the God of our fathers, believing everything laid down by the Law and written in the Prophets…” Acts 24:14 (ESV)
“Factions” or “sect” Greek: “hairesis” – disunion, a choice, a party, heresy
“As for a person who stirs up division (a heretic), after warning him once and then twice, have nothing more to do with him, knowing that such a person is warped and sinful; he is self-condemned.” Titus 3:10-11 (ESV)
“Division” or “Divisive” Greek: “aihretikos” – able to take or choose a thing, schismatic, heretic, factious, follower of false doctrine
King James Version (KJV);
“Heretick” – Greek: “aihretikos” – able to take or choose a thing, schismatic, heretic, factious, follower of false doctrine
Revised Version (RV); Apostolic Bible Polygot
“heretical” – Greek: “aihretikos” – able to take or choose a thing, schismatic, heretic, factious, follower of false doctrine

“Factious” – Greek: “aihretikos” – able to take or choose a thing, schismatic, heretic, factious, follower of false doctrine
Heresy becomes apostasy when there is a deliberate holding to error in spite of knowing the truth of the Word of God. A heretic becomes apostate at the point when he hears the truth and decides against it.
“[As for] a man who is factious [a heretical sectarian and cause of divisions], after admonishing him a first and second time, reject [him from your fellowship and have nothing more to do with him], Well aware that such a person has utterly changed (is perverted and corrupted); he goes on sinning [though he] is convicted of guilt and self-condemned.” ~ Titus 3:10-11 (Amplified Bible)
