We believe that, to attain the true knowledge of this great mystery, the Holy Spirit kindles in our hearts an upright faith, which embraces Jesus Christ with all His merits, appropriates Him, and seeks nothing more besides Him. For it must needs follow, either that all things which are requisite to our salvation are not in Jesus Christ, or if all things are in Him, that then those who possess Jesus Christ through faith have complete salvation in Him. Therefore, for any to assert that Christ is not sufficient, but that something more is required besides Him, would be too gross a blasphemy; for hence it would follow that Christ was but half a Savior.
Therefore we justly say with Paul, that we are justified by faith alone, or by faith apart from works. However, to speak more clearly, we do not mean that faith itself justifies us, for it is only an instrument with which we embrace Christ our righteousness. But Jesus Christ, imputing to us all His merits, and so many holy works which He has done for us and in our stead, is our righteousness. And faith is an instrument that keeps us in communion with Him in all His benefits, which, when they become ours, are more than sufficient to acquit us of our sins.
We believe that our salvation consists in the remission of our sins for Jesus Christ's sake, and that therein our righteousness before God is implied; as David and Paul teach us, declaring this to be the blessedness of man that God imputes righteousness to him apart from works. And the same apostle says that we are justified freely by his grace, through the redemption that is in Christ Jesus.
And therefore we always hold fast this foundation, ascribing all the glory to God, humbling ourselves before Him, and acknowledging ourselves to be such as we really are, without presuming to trust in anything in ourselves, or in any merit of ours, relying and resting upon the obedience of Christ crucified alone, which becomes ours when we believe in Him. This is sufficient to cover all our iniquities, and to give us confidence in approaching to God; freeing the conscience of fear, terror, and dread, without following the example of our first father, Adam, who, trembling, attempted to cover himself with fig-leaves. And, verily, if we should appear before God, relying on ourselves or on any other creature, though ever so little, we should, alas! be consumed. And therefore every one must pray with David: O Jehovah, enter not into judgment with thy servant: for in thy sight no man living is righteous.
