OLBGrk;
A man that is an heretic: two things make up a heretic according to the common acceptation of the term now:
1. An error in some matters of faith.
2. Stubbornness and contumacy in the holding and maintaining of it. Whether it so signified so early I cannot tell; it seems to refer to the former verse, supposing some that, notwithstanding all the endeavours of Titus, would be striving and contending for niceties about questions, genealogies, &c. After the first and second admonition reject: for such, saith the apostle, admonish them once and again; if they will not have done, refuse them, reject them. Whether excommunication can be certainly built upon this text, may be doubted; paraiteomai signifies no more than to avoid, reject, or refuse.
