“But now you rejoice in your arrogancies. All such rejoicing is wicked.”
“The proud person and pride occupy themselves with unreal things, which is why the proud one is so called — meaning "one living in delusion or deception." All such boasting is evil.”
“now--as it is. rejoice in . . . boastings--"ye boast in arrogant presumptions," namely, vain confident fancies that the future is certain to you (Jam 4:13). rejoicing--boasting [BENGEL].”
“All such rejoicing is wicked. To one therefore knowing to do good, and not doing it: to him it is sin. "All such rejoicing is wicked." James repeats the empty boasting that desires to arise from pride, and as if concluding his speech, he supposes that it is evil: if it is evil, it is certainly also from the Evil One. However, those who have been consecrated to the Lord through baptism should not receive any corruptions from the Evil One. He also infers this: Therefore, he who knows how to do right and does not do it is held by sin; he also rebukes false teachers. Do you dare to rebuke these things when you have not first acted rightly in them? "For blessed," he says, "is not he who has taught, but he who has both done and taught." (Matt. 5:17) For it is necessary that works precede the word, since the righteous proclaim the faith they have exhibited. "For whoever breaks one of these least commandments," says the Lord, "and teaches men so, that is, in vain, namely in those things in which he has not labored, shall be called least; but he who has both done and taught shall be called great." (Matt. 3:19) Since both God and man taught this doctrine which He had begun to practice first. It also seems to be the case that Paul says: "Let him who boasts, boast in the Lord;" (2 Cor. 10:17) that is, according to the Lord, using His example long before, and thus doing and teaching. For when David says: "My soul shall make its boast in the Lord," (Ps. 33:3) he says nothing other than that by walking according to the Lord's commandments, he is praised.”
The in-app commentary runs from the Fathers to the early-modern record, then stops — that's where the public-domain sources end, not where the reading does. For the modern reading, follow the sources directly.
