Thematic Bible: Those that teach doctrines contrary to Christ’s

If anyone teaches a different doctrine, and does not consent to sound words, the words of our Lord Jesus Christ, and to the doctrine which is according to godliness, he is conceited, knowing nothing, but obsessed with arguments, disputes, and word battles, from which come envy, strife, reviling, evil suspicions, constant friction of people of corrupt minds and destitute of the truth, who suppose that godliness is a means of gain.

For there are also many unruly men, vain talkers and deceivers, especially those of the circumcision, whose mouths must be stopped; men who overthrow whole houses, teaching things which they ought not, for dishonest gain's sake. One of them, a prophet of their own, said, "Cretans are always liars, evil beasts, and idle gluttons." read more.
This testimony is true. For this cause, reprove them sharply, that they may be sound in the faith, not paying attention to Jewish myths and commandments of men who turn away from the truth. To the pure, all things are pure; but to those who are defiled and unbelieving, nothing is pure; but both their mind and their conscience are defiled. They profess that they know God, but by their works they deny him, being abominable, disobedient, and unfit for any good work.

As I urged you when I was going into Macedonia, stay at Ephesus that you might command certain men not to teach a different doctrine, neither to pay attention to myths and endless genealogies, which cause speculation, rather than God's stewardship, which is in faith? but the goal of this command is love, out of a pure heart and a good conscience and unfeigned faith; read more.
from which things some, having missed the mark, have turned aside to vain talking; desiring to be teachers of the law, though they understand neither what they say, nor about what they strongly affirm.
