What the Bible says to do with heretics (hereticks) and two legged swine and dogs when they try to poison the church with heresy. A heretic is not just an argument over election of freewill since the Bible mentions both. A heresy is the denial of a major Bible doctrine like did Jesus cast out devils (demons) by the power of God or Satan? That is a major doctrine which denies the gospel among judaism.
Titus 3:10 - A man that is an heretick after the first and second admonition reject;
Deuteronomy 23:17 - There shall be no whore of the daughters of Israel, nor a sodomite of the sons of Israel.

Mark 3:22 - And the scribes which came down from Jerusalem said, He hath Beelzebub, and by the prince of the devils casteth he out devils.
Mar 3:23 - And he [Jesus] them unto him, and said unto them in parables, How can Satan cast out Satan?
Mar 3:24 - And if a kingdom be divided against itself, that kingdom cannot stand.
Mar 3:25 - And if a house be divided against itself, that house cannot stand.
Mar 3:26 - And if Satan rise up against himself, and be divided, he cannot stand, but hath an end.
Mar 3:27 - No man can enter into a strong man's house, and spoil his goods, except he will first bind the strong man; and then he will spoil his house.
Mar 3:28 - Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme: But he that shall blaspheme against the Holy Ghost hath never forgiveness, but is in danger of eternal damnation:
Mar 3:30 - Because they said, He hath an unclean spirit.
