Ps 49:1

“Here the divine prediction clearly prophesies that God will come manifestly, meaning none other but the Word of God. And it shows the reason of his coming, again emphasizing the calling of all nations of the world. For it says, "he has called the earth from the rising of the sun to the setting"; and it teaches that the rejection of the outward worship according to the Mosaic law will follow hard after his manifestation and the calling of the Gentiles, a worship that actually ceased after the manifestation of the Word of God to all people. For from that day to this all people throughout all the world have been called, and all the nations of the east and west. And the former worship has ceased and been abolished, all people being called to worship according to the new covenant of the preaching of the gospel, and not according to the law of Moses. We might also apply these prophecies to our Savior's second and glorious coming.”

“"The God," therefore, "of gods, the Lord has spoken" [Psalm 50:1]. Hath spoken many ways. By Angels He has Himself spoken, by Prophets He has Himself spoken, by His own mouth He has Himself spoken, by His faithful He does Himself speak, by our lowliness, when we say anything true, He does Himself speak. See then, by speaking diversely, many ways, by many vessels, by many instruments, yet He does Himself sound everywhere, by touching, moulding, inspiring: see what He has done. For "He has spoken, and has called the world." What world? Africa, perhaps! For the sake of those that say, the Church of Christ is the portion of Donatus. Africa indeed alone He has not called, but even Africa He has not severed. For He that "has called the world from the rising of the sun unto the going down," leaving out no parts that He has not called, in His calling has found Africa. Let it rejoice therefore in unity, not pride itself in division. We say well, that the voice of the God of gods has come even into Africa, has not stayed in Africa. For "He has called the world from the rising of the sun unto the going down." There is no place where may lurk the conspiracies of heretics, they have no place wherein they may hide themselves under the shadow of falsehood; for "there is none that can hide himself from the heat thereof." He that has called the world, has called even the whole world: He that has called the world, has called as much as He has formed. Why do false christs and false prophets rise up against me? Why is it that they strive to ensnare me with captious words, saying, "Lo! Here is Christ, Lo! He is there!" [Matthew 24:23] I hear not them that point out portions: the God of gods has pointed out the whole: "He" that "has called the world from the rising of the sun unto the going down," has redeemed the whole; but has condemned them that lay false claim to portions.”

“"The Lord, the God of gods, has spoken and called the earth from the rising of the sun until its setting." The power of the Lord is proclaimed in advance so that no one might believe that his incarnation ought to be deemed as being of moderate import and so that the depravity of all unbelief may be removed. Human beings who receive the grace of the divine majesty for their good conduct are called "gods," just as he says in another psalm, "I have said, 'You are gods and children of the Most High.' " Therefore, they are called "children," just as they are called "gods," because grace, not nature, offers each title. But the God of the gods is the Lord Christ, for he himself (along with the Father and the Holy Spirit) is truly called God of the gods. Nonetheless, the name "God of gods" does not altogether belong to the Divinity, but as we have already said, human language cannot indicate his exalted stature beyond this.”

“Above, the Psalmist invited the nations to trust in God; here he instructs them in the worship of God. The title: "A Psalm of Asaph." This Asaph was one of those placed over the singers of the people, and over those who sang and praised with cymbals, as is said in 1 Chr. 13 and 16 and 25. And it is called a Psalm of Asaph because it is sung by the ministry of Asaph. And it is fitting to the mystery, because Asaph is interpreted as "synagogue," and thus the person of the synagogue is read here. Where, instructed concerning sacrifices, he proposes two things about the worship of God that precede the divine judgment; and this is the first. The second is the disputation of God with the people concerning his worship, at "Hear, O my people." Before the judgment there will be three things: the citation of the judge, the coming of the judge, and the preparation. First, therefore, he sets forth the citation; second, the coming, at "Our God shall come manifestly"; third, the preparation, at "A fire before his sight." Concerning the first he does three things. First, he shows who the summoner is; second, who are summoned, at "And he called"; third, in what order they are summoned, at "Out of Zion." He who summons is great, because he is the God of all, even of gods. Hence he says, "The God of gods, the Lord, has spoken." First, therefore, he is commended for the excellence of his nature, because the God of gods, not an Angel. Jerome has, "the mighty God." But are there many gods? 1 Cor. 8: "For indeed there are many gods and many lords." For "God" is said in three ways: namely, by nature -- and this is but one God. Dt. 6: "Hear, O Israel, the Lord your God is one." Likewise, by participation, and these are many. 1 Cor. 8. Likewise, by designation and opinion, such as idols and stars, Venus and Saturn. Ps. 95: "All the gods of the nations are demons." But certain ones can be called gods in four ways. In one way, by union; and thus Christ alone is called God. Jn. 20: "My Lord and my God." Others by the grace of adoption. Ps. 81: "I said, you are gods," etc. Some by participation in divine power in working miracles. Ex. 7: "I have made you the god of Pharaoh." Others by ministry, as judges. Ex. 22: "You shall not detract from the gods." Likewise, he is commended for his governance, when he says, "The Lord has spoken." He spoke interiorly through inspiration. Ps. 84: "I will hear what the Lord God speaks in me." Likewise, by exterior speech. Heb. 1: "In these last days he has spoken to us," etc. "And he called the earth," namely the whole earth, that is, all the inhabitants of the earth. Hence those summoned are not only some in the middle of the world, but "from the rising of the sun to its setting." Mk. 16: "Going into the whole world," etc. Jer. 16: "The nations shall come to you from the ends of the earth and shall say: Surely our fathers possessed falsehood," etc.”
