Also they teach that men cannot be justified before God by their own strength, merits, or works, but are freely justified for Christ’s sake, through faith, when they believe that they are received into favor, and that their sins are forgiven for Christ’s sake, who, by His death, has made satisfaction for our sins. This faith God imputes for righteousness in His sight. Rom. 3 and 4.
And then here is further defense against Roman Catholics:
But since we receive remission of sins and the Holy Ghost by faith alone, faith alone justifies, because those reconciled are accounted righteous and children of God, not on account of their own purity, but through mercy for Christ’s sake, provided only they by faith apprehend this mercy. Accordingly, Scripture testifies that by faith we are accounted righteous, Rom. 3:26. We, therefore, will add testimonies which clearly declare that faith is that very righteousness by which we are accounted righteous before God, namely, not because it is a work that is in itself worthy, but because it receives the promise by which God has promised that for Christ’s sake He wishes to be propitious to those believing in Him, or because He knows that Christ of God is made unto us wisdom, and righteousness, and sanctification, and redemption, 1 Cor. 1:30.
What I like about these statements is that they respect the wording in Romans 4.4-5.
