Psalms 47:3

When did he subject people under our feet? When he chose his inheritance for us from the person of Mary, whom the Holy Spirit chose. Then, he ascended with a shout and voice of trumpet.… Glory to God on high, angels tell the shepherds. Behold, the Lord rules over every nation. The Lord sits on his holy seat.

What a marvel! He convinced those who crucified him to bow down in worship; those who mocked and blasphemed, those addicted to idol worship he taught to let their souls yield to his will. This transformation, you see, was not of the apostles' doing but done by him who led the way before them and moved their spirit. I mean, how could a fisherman or a builder have so changed the world had not the words of this person cleared all these obstacles? Sorcerers and tyrants and demagogues and philosophers and all their opponents they scared away like grains of dust and dissipated like smoke. In this way they spread the light of truth, employing not weapons or abundance of wealth but simple speech—or, rather, the speech was not simple but more potent than any action. So how? They called on the name of the crucified, and death skulked away, demons were put to flight, diseases were cured, bodily disfigurement righted, wickedness dispelled, dangers dissipated and the elements transformed.… He it was who removed the obstacles as he went before them; he himself smoothed out problems and made difficult things easy. And yet everything was beset by conflicts, everything with snares and hazards, no foothold or places to stand firm, all havens obstructed, every house shut, the ears of all stopped. Nevertheless, as soon as they entered and spoke, all strongholds of the enemy fell, with the result that they even surrendered their souls and then withstood countless dangers for the sake of what they had been told.

"He has subdued the people under us, and the nations under our feet" [Psalm 47:3]. Which subdued, and to whom? Who are they that speak? Haply Jews? Surely, if Apostles; surely, if Saints. For under these God has subdued the people and the nations, that today are they honoured among the nations, who by their own citizens earned to be slain: as their Lord was slain by His citizens, and is honoured among the nations; was crucified by His own, is adored by aliens, but those by a price made His own. For therefore bought He us, that aliens from Him we might not be. Do you think then these are the words of Apostles, "He has subdued the people under us, and the nations under our feet"? I know not. Strange that Apostles should speak so proudly, as to rejoice that the nations were put under their feet, that is, Christians under the feet of Apostles. For they rejoice that we are with them under the feet of Him who died for us. For under Paul's feet ran they, who would be of Paul, to whom He said, "Was Paul crucified for you?" [1 Corinthians 1:13] What then here, what are we to understand? "He has subdued the people under us, and the nations under our feet." All pertaining to Christ's inheritance are among "all the nations," and all not pertaining to Christ's inheritance are among "all the nations:" and you see so exalted in Christ's Name is Christ's Church, that all not yet believing in Christ lie under the feet of Christians. For what numbers now run to the Church; not yet being Christians, they ask aid of the Church; to be succoured by us temporally they are willing, though eternally to reign with us as yet they are unwilling. When all seek aid of the Church, even they who are not yet in the Church, has He not "subdued the people under us, and the nations under our feet"?
