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.
It may, at first, seem that the word necessarily makes little difference. But adding that suggests that good works must follow faith, as a rule and not a choice. The Episcopal Articles add another about works before justification. It is a rather strong statement that works before justification have the nature of sin.
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 judgment; 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.
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.
