Christian Heresies


Heresy is a false teaching. It is a belief or idea that is in contradiction to orthodoxy. In the context of Christianity, heresy is that which deviates from standard biblical teaching. Examples of heresy would be polytheism, a denial of the resurrection of Christ, a teaching that salvation is obtained by works, etc. The Christian church has experienced many attacks by heretics throughout the centuries, but it has fought them successfully - even though many persist. There are modern-day heresies. For example, Mormonism which teaches God is an exalted man from another planet and that we can become gods. The Jehovah's Witnesses deny the Trinity, deny the deity of Christ, and deny salvation by grace alone through faith alone. Roman Catholicism also and works to salvation and promotes Mary worship.

"Error, indeed, is never set forth in its naked deformity, lest, being thus exposed, it should at once be detected. But it is craftily decked out in on attractive dress, so as, by its outward form, to make it appear to the inexperienced (ridiculous as the expression may seem) more true than truth itself," (Irenaeus Against Heresies 1.2).

The word "heresy" comes from the Greek 'hairesis' which means "choosing" or "faction." At first, the term heresy did not carry the negative meaning it does now. But, as the early church grew in its scope and influence throughout the Mediterranean area, various teachers proposed controversial ideas about Christ, God, salvation, and other biblical themes. It became necessary for the church to determine what was and was not true according to the Bible.

Theologically, the Bible teaches condemnation upon false doctrines and false teachers. Gal. 1:8-9 says, "But even though we, or an angel from heaven, should preach to you a gospel contrary to that which we have preached to you, let him be accursed. 9 As we have said before, so I say again now, if any man is preaching to you a gospel contrary to that which you received, let him be accursed." (See also 1 Cor. 16:22; 2 Cor. 11:13-15; 1 Tim. 1:18-20; Titus 3:10) Why is this taught in the Bible? The reason is simple. Christians are saved by faith in the work of Jesus on the cross, but faith in itself is not enough. Faith is not a substance you can put in a jar. It is belief in something. Faith is only as good as who it is placed in. If you put your faith in a false God, you are lost because a false god cannot save anyone. This is why God says in Exodus 20:3, "You shall have no other gods before Me." Faith is not what saves, but faith in the true God is what saves.

Christian heresies are many.  Through studying such errors as arianism, gnosticism, modalism, and pelagianism, Christians can better understand their own faith.  A heresy is a deviation from the truth.

"For there must also be factions among you, in order that those who are approved may have become evident among you," (1 Cor. 11:19).
