Responsorial Psalm — Psalm 145:10-11, 12-13ab, 21
Ps 144:10-11
Let all thy works, O lord, praise thee: and let thy saints bless thee.11 They shall speak of the glory of thy kingdom: and shall tell of thy power:12 To make thy might known to the sons of men: and the glory of the magnificence of thy kingdom.13 Thy kingdom is a kingdom of all ages: and thy dominion endureth throughout all generations. The Lord is faithful in all his words: and holy in all his works.21 My mouth shall speak the praise of the Lord: and let all flesh bless thy holy name for ever; yea, for ever and ever.
A person, then, who remains the same and yet babbles to himself about the change for the better he has undergone in baptism should attend to what Paul says: "If anyone thinks he is something when he is nothing, he deceives himself." For you are not what you have not become; whereas the gospel says of the regenerate that "he gave all those who received him the power to become God's children." Now the child born of someone certainly shares his parent's nature. If, then, you have received God and become his child, let your way of life testify to the God within you; make it clear who your Father is! The marks by which we recognize God are the very ones by which a son of his must show his relation to him: "he opens his hand and fills everything living with joy"; "he overlooks iniquity"; "he relents of his evil purpose";29 "the Lord is kind to all and is not angry with us every day"; "God is straightforward, and there is no unrighteousness in him"31—and the similar sayings scattered through Scripture for our instruction. If you are like this, you have genuinely become a child of God. But if you persist in displaying the marks of evil, it is useless to babble to yourself about the birth from above. Prophecy will tell you, "You are a son of humankind, not a son of the most High. You love vanity and seek lies. You fail to realize that the only way one is magnified is by becoming holy."
Peace I leave with you, my peace I give unto you: not as the world giveth, do I give unto you. Let not your heart be troubled, nor let it be afraid.28 You have heard that I said to you: I go away, and I come unto you. If you loved me, you would indeed be glad, because I go to the Father: for the Father is greater than I.†29 And now I have told you before it comes to pass: that when it shall come to pass, you may believe.30 I will not now speak many things with you. For the prince of this world cometh, and in me he hath not any thing.31 But that the world may know, that I love the Father: and as the Father hath given me commandment, so do I: Arise, let us go hence.
(de Trin. ix) Or thus: If the Father is greater by virtue of giving, is the Son less by confessing the gift? The giver is the greater, but He to whom unity with that giver is given, is not the less.
