#56 Art. IV “Justification” of the Apology of the Augsburg Confession.Some one of them may ask; “Since we acknowledge that love is the offspring of the Spirit, and since it is called a holy work and the fulfillment of the law, why we do not also teach that it justifies us before God?”
Reply,—First, most assuredly we do not receive the forgiveness of sins either through love or on account of it, but through faith alone for Christ’s sake. Faith alone in the heart looks upon the promises of God; faith alone is the assurance, upon which the heart rests with certainty, that God is merciful— that Christ died not in vain, &c. This faith alone overcomes the terrors of sin and death. He that still wavers, or doubts that his sins are remitted, does not confide in God, but he despairs of Christ; because he believes his sins to be greater and stronger than the death and blood of Christ; and yet Paul says, Rom. 5:20, that, “Where sin abounded, grace did much more abound,” that is, it was stronger, richer, and more powerful.
Now if any one expects to obtain the remission of his sins, on account of his love, he reviles and dishonors Christ, and will discover, in his last moments, when he must appear before the judgment seat of God, the vanity of such confidence. It is therefore certain, that we are justified by faith alone. And as we do not obtain the remission of sin by good works and virtues; such as patience, chastity, obedience to government, and yet these virtues follow faith; so we do not obtain remission of sin on account of love to God, although it must follow faith. (Henkel Translation, p. 184).
