John Calvin's Commentary on the Bible

22 (James 2:22)

Verse 22

22By works was faith made perfect (119) By this he again shews, that the question here is not respecting the cause of our salvation, but whether works necessarily accompany faith; for in this sense it is said to have been perfected by works, because it was not idle. It is said to have been perfected by works, not because it received thence its own perfection, but because it was thus proved to be true. For the futile distinction which the Sophists draw from these words, between formed and unformed faith, needs no labored refutation; for the faith of Abram was formed and therefore perfected before he sacrificed his son. And this work was not as it were the finishing, or last work. Formerly things afterwards followed by which Abraham proved the increase of his faith. Hence this was not the perfection of his faith, nor did it then for the first time put on its form. James then understood no other thing, than that the integrity of his faith then appeared, because it brought forth that remarkable fruit of obedience.
