According to Lutheran theology, the true opposite of synergism is not Calvinism with its double election, irresistible grace, denial of universal redemption, etc., but the monergism of grace, embracing particularly the tenets that in consequence of Adam's fall man is spiritually dead and utterly unable to contribute in any degree or manner toward his own justification and conversion; moreover, that, being an enemy of God, man, of his own natural powers, is active only in resisting the saving efforts of God, as well as able and prone only to do so; that God alone and in every respect is the Author of man's conversion, perseverance, and final salvation; and that, since the grace of God is universal and earnestly proffered, man alone is responsible for, and the cause of, his own damnation. _"Sola fides iustificat,_ Faith alone justifies"--that was the great slogan of the Reformation sounded forth by Luther and his followers with ever increasing boldness, force and volume. And the distinct meaning of this proposition, which Luther called "_hoc meum dogma,_ this my dogma," was just this, that we are saved not by any effort or work of our own, but in every respect by God's grace alone. The restoration of this wonderful truth, taught by St. Paul, made Luther the Reformer of the Church. This truth alone, as Luther had experienced, is able to impart solid comfort to a terror-stricken conscience, engender divine assurance of God's pardon and acceptance, and thus translate a poor miserable sinner from the terrors of hell into paradise.
