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.
