Sola gratia is one of the five solas propounded to summarise the Reformers' basic beliefs during the Protestant Reformation; it is a Latin term meaning grace alone. The emphasis was in contradistinction to the teaching of the Roman Catholic Church of the day. Catholic doctrine, as defined by the Council of Trent, holds that salvation is made possible only by grace; the faith and works of men are secondary means that have their origins in and are sustained by grace.
During the Reformation, Protestant leaders and theologians generally believed the Roman Catholic view of the means of salvation to be a mixture of reliance upon the grace of God, and confidence in the merits of one's own works performed in love, pejoratively called Legalism. The Reformers posited that salvation is entirely comprehended in God's gifts (that is, God's act of free grace), dispensed by the Holy Spirit according to the redemptive work of Jesus Christ alone. Consequently, they argued that a sinner is not accepted by God on account of the change wrought in the believer by God's grace, and indeed, that the believer is accepted without any regard for the merit of his works—for no one deserves salvation, a concept that some take to the extreme of Antinomianism.
Sola gratia is one of the Protestant Reformation's Five Solas and is also linked to the five points of Calvinism.
In November 1999, the Lutheran World Federation and the Catholic Church issued the "Joint Declaration on the Doctrine of Justification" that said, "By grace alone, in faith in Christ's saving work and not because of any merit on our part, we are accepted by God and receive the Holy Spirit, who renews our hearts while equipping us and calling us to good works." On July 18, 2006, delegates to the World Methodist Conference voted unanimously to adopt the declaration. The Methodists' resolution said the 1999 agreement "expresses a far-reaching consensus in regard to the theological controversy which was a major cause of the split in Western churches in the 16th century" over salvation by grace alone or by grace and good works. Many conservative Protestant and Catholic groups still believe the differences between their views remain substantial, however.
