The Lord hath said to me: Thou art my son, this day I have begotten thee. Ask of me, and I will give thee the Gentiles for thy inheritance, and the uttermost parts of the earth for thy possession. (Psalm 2:7, 8)
Christ did not become King to exact tribute, to equip armies, nor subdue visible foes
What a stupendous thing it was for the King of the ages to become King of men! For Christ did not become King of Israel to exact tribute, to equip armies with swords, nor subdue visible foes. He became King of Israel that he might rule over men’s souls, counsel them about eternity, that he might lead to the kingdom of heaven those who believe in him, hope in him, and love him.
Christ became King that he might rule over men’s souls, counsel them about eternity, that he might lead to the kingdom of heaven those who believe in him, hope in him, and love him.
Accordingly, it was not to increase his power, but condescension on his part that made him – the Son of God, co-equal with the Father, the Word by whom all things were made – wish to become King of Israel. It was an indication of his mercy; it did not augment his power.
He who on earth was called King of the Jews, in heaven is called Lord of the angels. But is Christ King of the Jews only, and not King of the Gentiles, too? Yes, he is King of the Gentiles, too. When in prophecy he said, “But I have established my kingdom upon Sion, my holy mountain. I will proclaim the decree of the Lord,” he added immediately so that the mention of Mount Sion might not lead men to believe he had been anointed King of the Jews solely: “You are my Son; this day I have begotten you. Ask of me and I will give you the nations for an inheritance, and the ends of the earth for your possession.
