But some man will say: Thou hast faith, and I have works: shew me thy faith without works; and I will shew thee, by works, my faith.

“Even if somebody believes rightly in the Father and the Son, as well as in the Holy Spirit, if he does not lead the right kind of life, his faith will not benefit him at all as far as his salvation is concerned. For although Jesus says: "This is eternal life, to know you, the only true God," we must not think that merely uttering the words is enough to save us. For our life and behavior must be pure as well.”

“Show me thy faith without thy works - Your pretending to have faith, while you have no works of charity or mercy, is utterly vain: for as faith, which is a principle in the mind, cannot be discerned but by the effects, that is, good works; he who has no good works has, presumptively, no faith. I will show thee my faith by my works - My works of charity and mercy will show that I have faith; and that it is the living tree, whose root is love to God and man, and whose fruit is the good works here contended for.”

“Some men will say: Thou hast faith, and I have works. Shew me thy faith, &c. He confutes the same error, by putting them in mind that one can shew that he has faith, which is an interior virtue, only by good works, and that good works in a man shew also his faith; which is not to be understood, as if good works were merely the marks, signs, and effects of faith, as some would pretend, but that good works must concur with faith to a man’s salvation by an increase in grace. (Witham)”

“"But some one will say": so the Greek. This verse continues the argument from Jam 2:14, Jam 2:16. One may say he has faith though he have not works. Suppose one were to say to a naked brother, "Be warmed," without giving him needful clothing. "But someone (entertaining views of the need of faith having works joined to it) will say (in opposition to the 'say' of the professor)." show me thy faith without thy works--if thou canst; but thou canst not SHOW, that is, manifest or evidence thy alleged (Jam 2:14, "say") faith without works. "Show" does not mean here to prove to me, but exhibit to me. Faith is unseen save by God. To show faith to man, works in some form or other are needed: we are justified judicially by God (Rom 8:33); meritoriously, by Christ (Isa 53:11); mediately, by faith (Rom 5:1); evidentially, by works. The question here is not as to the ground on which believers are justified, but about the demonstration of their faith: so in the case of Abraham. In Gen 22:1 it is written, God did tempt Abraham, that is, put to the test of demonstration the reality of his faith, not for the satisfaction of God, who already knew it well, but to demonstrate it before men. The offering of Isaac at that time, quoted here, Jam 2:21, formed no part of the ground of his justification, for he was justified previously on his simply believing in the promise of spiritual heirs, that is, believers, numerous as the stars. He was then justified: that justification was showed or manifested by his offering Isaac forty years after. That work of faith demonstrated, but did not contribute to his justification. The tree shows its life by its fruits, but it was alive before either fruits or even leaves appeared.”
