Psalms 100:1

1Make a joyful noise The Psalmist refers only to that part of the service of God which consists in recounting his benefits and giving thanks. And since he invites the whole of the inhabitants of the earth indiscriminately to praise Jehovah, he seems, in the spirit of prophecy, to refer to the period when the Church would be gathered out of different nations. Hence he commands (verse 2) that God should be served with gladness, intimating that his kindness towards his own people is so great as to furnish them with abundant ground for rejoicing. This is better expressed in the third verse, in which he first reprehends the presumption of those men who had wickedly revolted from the true God, both in fashioning for themselves gods many, and in devising various forms of worshipping them. And as a multitude of gods destroys and suppresses the true knowledge of one God only, and tarnishes his glory, the prophet, with great propriety, calls upon all men to bethink themselves, and to cease from robbing God of the honor due to his name; and, at the same time, inveighs against their folly in that, not content with the one God, they were become vain in their imaginations. For, however much they are constrained to confess with the mouth that there is a God, the maker of heaven and earth, yet they are ever and anon gradually despoiling him of his glory; and in this manner, the Godhead is, to the utmost extent of their power, reduced to a nonentity. As it is then a most difficult thing to retain men in the practice of the pure worship of God, the prophet, not without reason, recalls the world from its accustomed vanity, and commands them to recognize God as God. For we must attend to this short definition of the knowledge of him, namely, that his glory be preserved unimpaired, and that no deity be opposed to him that might obscure the glory of his name. True, indeed, in the Papacy, God still retains his name, but as his glory is not comprehended in the mere letters of his name, it is certain that there he is not recognized as God. Know, therefore, that the true worship of God cannot be preserved in all its integrity until the base profanation of his glory, which is the inseparable attendant of superstition, be completely reformed.
