D-R Bible, Haydock Commentary:
Ver. 21. Here Jesus Christ shews, that it is not sufficient to believe in him and hear his words, but that in order to salvation, we must join works with faith; for in this shall we be examined at the last day. (Menochius) — Without faith they could not cry out, Lord, Lord. (Romans x.) But the strongest faith without the works of justice, will not be available to salvation. (1 Corinthians xiii.) (Bristow) — Many who have the Lord continually in their mouths, but care little about putting on the Lord, or penetrating themselves with his true spirit, will find their presumption, and the false consciences they have made to themselves, wofully disappointed. (Haydock)
Ver. 22. Have not we prophesied in thy name? The gift of prophecy, and of doing miracles, may sometimes be granted to bad men, as to Caiphas, and Balaam. (Witham) — Under the name of prophets, the Hebrews comprised not only such as predicted future events, but also in general all such as gave themselves out for inspired, or who undertook teaching and interpreting the holy Scriptures; and here by prophesying is understood, in a general acceptation, all public functions, predicting futurity, expounding Scripture, instructing the people, preaching, &c. (Bible de Vence)
Ver. 23. So as to approve and reward your works. Here he shews that even prophecy and miracles will not save us without good works. (Menochius) — How much less will faith, unassisted by good works, preserve us from condemnation. (Haydock) — The gift of miracles is bestowed on men not for their own good, but for the advantage of others. We must not then be surprised if men, who had indeed faith in Christ, but whose lives did not correspond with their faith, should be honoured with these extraordinary gifts, since the Almighty sometimes employs as his instruments in working similar wonders, men destitute both of faith and virtue. Balaam, void of faith and probity, still by the will of God, prophesied for the advantage of others. To Pharao and Nabuchodonosor were revealed future events of the greatest moment; and the wicked Judas himself cast out devils. Therefore St. Paul said, “if I had all faith so as to remove mountains, and if I knew all mysteries, and was possessed of all wisdom, but had not charity, I am nothing.” (St. Chrysostom, Hom. xv.)
Ver. 24. In the Greek text, “I will compare him;” an apposite comparison, to shew the necessity of good works. It is the duty of each individual to erect this spiritual edifice of good works in the interior of his soul, which may be able to resist all the attacks of our spiritual enemy: whilst those men who have true faith and no works are compared to a fool, and are sure to perish. (Menochius) —Here again our Saviour dispenses his rewards to such as order their lives according to his instructions; but as before he promised the kingdom of heaven, divine consolations, and other rewards, so here he promises them the numberless blessings attendant on virtue in this life. The just alone are surrounded with virtue as with a strong guard, and amidst the high swelling waves of worldly troubles, enjoy a calm and unchangeable tranquillity. Thus was Job strengthened by his virtue against the attacks both of men and satan. (St. Chrysostom, hom. xxv.)
Ver. 25. The Scribes and Pharisees only explained the law, and laid open the promises of Moses, whereas our Saviour gives new laws, and makes new promises in his own name; But I say to you, &c. The energy also with which our Saviour spoke, together with the miracles which he wrought, had far greater influence on the minds of the people than the frigid manner in which the Scribes delivered their doctrines. (Menochius)
