Justificatio sola fide (or simply sola fide), meaning justification by faith alone, is a soteriological doctrine in Christian theology commonly held to distinguish the Lutheran and Reformed traditions of Protestantism,[1] among others, from the Catholic, Eastern Orthodox, Oriental Orthodox, Assyrian and Anabaptist churches.[2][3] The doctrine asserts that it is on the basis of faith that believers are made right of their transgressions of divine law rather than on the basis of what Paul the Apostle calls "works of the law", sometimes called good works.[4] This forgiveness is known as "justification".
Galatians 3:6
King James Version
6 Even as Abraham believed God, and it was accounted to him for righteousness.
