Grace and Peace
Pelagianism derives its name from Pelagius who lived in the 5th century A.D. and was a teacher in Rome, though he was British by birth. It is a heresy dealing with the nature of man. Pelagius, whose family name was Morgan, taught that people had the ability to fulfill the commands of God by exercising the freedom of human will apart from the grace of God. In other words, a person's free will is totally capable of choosing God and/or to do good or bad without the aid of Divine intervention. Pelagianism teaches that man's nature is basically good. Thus it denies original sin, the doctrine that we have inherited a sinful nature from Adam. He said that Adam only hurt himself when he fell and all of his descendents were not affected by Adam's sin. Pelagius taught that a person is born with the same purity and moral abilities as Adam was when he was first made by God. He taught that people can choose God by the exercise of their free will and rational thought. God's grace, then, is merely an aid to help individuals come to Him.
Pelagianism fails to understand man's nature and weakness. We are by nature sinners (Eph. 2:3; Psalm 51:5). We all have sinned because sin entered the world through Adam: "Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all men, because all sinned" (Rom. 5:12, NIV). Furthermore, Romans 3:10-12 says, “There is none righteous, not even one; 11 There is none who understands, There is none who seeks for God; 12 All have turned aside, together they have become useless; There is none who does good, There is not even one.” Therefore, we are unable to do God's will (Rom. 6:16; 7:14). We were affected by the fall of Adam, contrary to what Pelagius taught.
