Chapter 3: Articles IX–XIV: Sin and Salvation
Section 9. Article IX. Of Original or Birth-sin. Original sin standeth not in the following of Adam, (as the Pelagians do vainly talk;) but it is the fault and corruption of the Nature of every man, that naturally is engendered of the offspring of Adam; whereby man is very far gone from original righteousness, and is of his own nature inclined to evil, so that the flesh lusteth always contrary to the spirit; and therefore in every person born into this world, it deserveth God's wrath and damnation. And this infection of nature doth remain, yea in them that are regenerated; whereby the lust of the flesh, called in the Greek, Phronema Sarkos, which some do expound the wisdom, some sensuality, some the affection, some the desire, of the flesh, is not subject to the Law of God. And although there is no condemnation for them that believe and are baptized, yet the Apostle doth confess, that concupiscence and lust hath of itself the nature of sin.
Section 10. Article X. Of Free-Will. The condition of Man after the fall of Adam is such, that he cannot turn and prepare himself, by his own natural strength and good works, to faith; and calling upon God: Wherefore we have no power to do good works pleasant and acceptable to God, without the grace of God by Christ preventing us, that we may have a good will, and working with us, when we have that good will.
Section 11. Article XI. 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, as more largely is expressed in the Homily of Justification.
Section 12. Article XII. Of Good Works. Albeit that Good Works, which are the fruits of Faith, and follow after Justification, cannot put away our sins, and endure the severity of God's Judgement; yet are they pleasing and acceptable to God in Christ, and do spring out necessarily of a true and lively Faith; insomuch that by them a lively Faith may be as evidently known as a tree discerned by the fruit.
Section 13. Article XIII. Of Works before Justification. Works done before the grace of Christ, and the Inspiration of his Spirit, are not pleasant to God, forasmuch as they spring not of faith in Jesus Christ; neither do they make men meet to receive grace, or (as the School-authors say) deserve grace of congruity: yea rather, for that they are not done as God hath willed and commanded them to be done, we doubt not but they have the nature of sin.
Section 14. Article XIV. 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 ye have done all that are commanded to you, say, We are unprofitable servants.
