Article 9.-Of the Justification of Man
We are accounted righteous before God only for the merit of our Lord and Saviour Jesus Christ, by faith, and not for our own works or deservings. Wherefore, that we are justified by faith, only, is a most wholesome doctrine, and very full of comfort.
Article 10.-Of Good Works
Although good works, which are the fruits of faith, and follow after justification, cannot put away our sins, and endure the severity of God's judgment; yet are they pleasing and acceptable to God in Christ, and spring out of a true and lively faith, insomuch that by them a lively faith may be as evidently known as a tree is discerned by its fruit.
Article 11.-Of Works of Supererogation
Voluntary works-besides, over and above God's commandments-which they call works of supererogation, cannot be taught without arrogancy and impiety. For by them men do declare that they do not only render unto God as much as they are bound to do, but that they do more for his sake than of bounden duty is required; whereas Christ saith plainly: When you have done all that is commanded you, say, We are unprofitable servants.
Article 12.-Of Sin After Justification
Not every sin willingly committed after justification is the sin against the Holy Ghost, and unpardonable. Wherefore, the grant of repentance is not to be denied to such as fall into sin after justification. After we have received the Holy Ghost, we may depart from grace given, and fall into sin, and, by the grace of God, rise again and amend our lives. And therefore they are to be condemned who say they can no more sin as long as they live here; or deny the place of forgiveness to such as truly repent.
