The Doctrine On Which the Church Stands or Falls
While we could point to many different factors that led the sixteenth-century Protestant Reformers to break from Rome, perhaps one that would be at the very top of the list is the doctrine of justification by faith alone. For Luther and Calvin, this doctrine is the very hinge on which the Christian religion turns. In part this is because sola fide is what sets Protestants apart. While every other religion puts something of man into the equation, Protestantism removes man’s works from the justification formula altogether. Therefore, the “sola” in sola fide makes all the difference in the world.
