As Adstar pointed out, Calvinism is based on the TULIP. Arminianism also has five main points to express its position (taken from
here):
Conditional Election: God has decreed to save through
Jesus Christ, out of fallen and sinful mankind, those foreknown by Him who through the grace of the Holy Spirit believe in Christ; but God leaves in sin those foreseen, who are incorrigible and unbelieving.
Universal Atonement: Christ's death was suffered on behalf of all men, but God elects for salvation only those who believe in Christ.
Free Will with Partial Depravity: Freedom of will is man's natural state, not a spiritual gift - and thus free will was not lost in the Fall, but cannot be exercised toward good apart from the grace of God. Grace works upon all men to influence them for good, but only those who freely choose to agree with grace by faith and repentance are given new spiritual power to make effectual the good they otherwise impotently intend. As John Wesley stated more forcefully, humans were in fact
totally corrupted by
original sin, but God's
prevenient grace allowed free will to operate.
Resistible Grace: The grace of God works for good in all men, and brings about newness of life through faith. But grace can be resisted even by the regenerate.
Uncertain Perseverance: Those who are incorporated into Christ by a true faith have power given them through the assisting grace of the Holy Spirit, sufficient to enable them to persevere in the faith. But it may be possible for a believer to fall from grace.
I am closest to Arminianism. Note that Arminianism is NOT the same thing as "neotheism" (called open theism on CF), which is an abuse of the Arminian position. The Eastern Orthodox go about interpreting salvation in still another way, called
theosis (deification). This does not literally mean "becoming God" in substance or in an ontological sense, as other religions may teach, but it does mean becoming like Christ, and participating
in God. This is where Orthodox Pan-entheism, God in all things (
not panen-theism, which says that all things are God), comes into play.
