3:10 heretick. This is the only occurrence of the Greek word hairetikos in the New Testament (though its derivative, “heretic” has been used frequently in church history). The similar word, hairesis (translated “heresy” or “sect”) occurs nine times. It was applied by the Jews to the Christians, and by the Christians to the Pharisees and Sadducees (Acts 5:17; 15:5; 24:5). Both Greek words are derived from hairetizo, meaning “choose.” There is no inherently evil meaning suggested, but simply a marked difference from a standard teaching. A heresy only becomes wrong when it substantially contradicts a clear doctrine of Scripture (e.g., theistic evolution, denial of the virgin birth).
