1- " The concept of original sin was first alluded to in the 2nd century by Irenaeus, Bishop of Lyons in his controversy with certain dualist Gnostics. Other church fathers such as Augustine also developed the doctrine,[2] seeing it as based on the New Testament teaching of Paul the Apostle (Romans 5:1221 and 1 Corinthians 15:22) and the Old Testament verse of Psalm 51:5.[4][5][6][7][8] Tertullian, Cyprian, Ambrose and Ambrosiaster considered that humanity shares in Adam's sin, transmitted by human generation. Augustine's formulation of original sin was popular among Protestant reformers, such as Martin Luther and John Calvin, who equated original sin with concupiscence, affirming that it persisted even after baptism and completely destroyed freedom.[2] Within Roman Catholicism, the Jansenist movement, which the Church then declared heretical, also maintained that original sin destroyed freedom of will.[9] On the other hand, some modern liberal Protestants deny that the doctrine has a basis in Scripture.[10].."

2- " In the fifth century, Augustine the Bishop of Hippo, was involved in a confrontation with the Pelagian movement, concerning the controversy of the nature of the fall of Adam and Eve. He proclaimed the Pelagian movement as being heretical because it taught that Adams sin affected only himself and not the human race as a whole; that every individual is born free of sin and is capable in his own power of living a sinless life and that there had even been persons who had succeeded in doing so."

Faith and Deeds
14 What good is it, my brothers and sisters, if someone claims to have faith but has no deeds? Can such faith save them?
26 As the body without the spirit is dead, so faith without deeds is dead.
