Interesting new blog out there called Suicide of the West - A continuing chronicle of Western cultural disintegration, as the author styles it.
Today, they posted an interesting list of heresies that have afflicted the Church at one time or another. Have you ever fallen into them? I can think of a couple.
Adoptionism - God granted Jesus powers and then adopted him as a Son.
Albigenses - Reincarnation and two gods: one good and other evil.
Apollinarianism - Jesus divine will overshadowed and replaced the human.
Arianism - Jesus was a lesser, created being.
Docetism - Jesus was divine, but only seemed to be human.
Donatism - Validity of sacraments depends on character of the minister.
Gnosticism - Dualism of good and bad and special knowledge for salvation.
Kenosis - Jesus gave up some divine attributes while on earth.
Modalism - God is one person in three modes.
Monarchianism - God is one person.
Monophysitism - Jesus had only one nature: divine.
Nestorianism - Jesus was two persons.
Patripassionism - The Father suffered on the cross
Pelagianism - Man is unaffected by the fall and can keep all of God’s laws.
Socinianism - Denial of the Trinity. Jesus is a deified man.
Tritheism - the Trinity is really three separate gods.
