For true and righteous are his judgments: for he hath judged the great whore, which did corrupt the earth with her fornication, and hath avenged the blood of his servants at her hand.

People's New Testament

19:2 For true and righteous are his judgments. This is shown by the judgments on the spiritual Babylon.

Wesley's Notes

19:2 For true and righteous are his judgments - Thus is the cry of the souls under the altar changed into a song of praise.

Jamieson-Fausset-Brown Bible Commentary

2. which did corrupt the earth-Greek, "used to corrupt" continually. "Instead of opposing and lessening, she promoted the sinful life and decay of the world by her own earthliness, allowing the salt to lose its savor" [Auberlen].

avenged-Greek, "exacted in retribution." A particular application of the principle (Ge 9:5).

blood of his servants-literally shed by the Old Testament adulterous Church, and by the New Testament apostate Church; also virtually, though not literally, by all who, though called Christians, hate their brother, or love not the brethren of Christ, but shrink from the reproach of the cross, and show unkindness towards those who bear it.

Matthew Henry's Concise Commentary

19:1-10 Praising God for what we have, is praying for what is yet further to be done for us. There is harmony between the angels and the saints in this triumphant song. Christ is the Bridegroom of his ransomed church. This second union will be completed in heaven; but the beginning of the glorious millennium (by which is meant a reign of Christ, or a state of happiness, for a thousand years on earth) may be considered as the celebration of his espousals on earth. Then the church of Christ, being purified from errors, divisions, and corruptions, in doctrine, discipline, worship, and practice, will be made ready to be publicly owned by him as his delight and his beloved. The church appeared; not in the gay, gaudy dress of the mother of harlots, but in fine linen, clean and white. In the robes of Christ's righteousness, imputed for justification, and imparted for sanctification. The promises of the gospel, the true sayings of God, opened, applied, and sealed by the Spirit of God, in holy ordinances, are the marriage-feast. This seems to refer to the abundant grace and consolation Christians will receive in the happy days which are to come. The apostle offered honour to the angel. The angel refused it. He directed the apostle to the true and only object of religious worship; to worship God, and him alone. This plainly condemns the practice of those who worship the elements of bread and wine, and saints, and angels; and of those who do not believe that Christ is truly and by nature God, yet pay him a sort of worship. They stand convicted of idolatry by a messenger from heaven. These are the true sayings of God; of Him who is to be worshipped, as one with the Father and the Holy Spirit.
