Psalm 32:5-6
The earth is full of the mercy of the Lord, alleluia: by the word of the Lord were the heavens made, alleluia, alleluia. Ps. Rejoice in the Lord, O ye righteous: praise is comely for the upright. V. Glory be to the Father. The earth is full.

Verse 5. Judgment. God joins these virtues together, (W.) as we ought to do. H. Lu. vi. 36. Mat. v. 48. — He punishes the wicked, and rewards the good. But his mercy displays itself on the earth, as there is no misery in heaven. S. Aug. — Its effects appear more since the coming of our Saviour. C.
Verse 6. Mouth, by his command. Euthym. Gen. i. 6. — The Fathers here find the blessed Trinity expressed; (C. M.) and the Council of Trent admonishes us to follow their unanimous interpretation, which is here adopted by Baumbgarte, a Prot. 1719. S. John informs us that all was made by the Word, from whom the Father and the Holy Spirit cannot be separated. Bert. — Seneca (consol. 8.) seems to have had some idea of this mystery. Quisquis formator universi fuit, sive ille Deus est potens omnium; sive incorporalis Ratio, ingentium operum artifex; sive divinus Spiritus, per omnia maxima et minima æquali intentione diffusus. The power of them may designate the stars and angels, which the Heb. styles “the army” of heaven. Is. xxiv. 21. Mat. xxvi. 53. C. — The word of God is omnipotent, (W.) “the Creator…both of visible and invisible things.” Nic. Creed. H. — Calvin rejects this proof of the Trinity as weak, (Amama) as he did not like the word Trinity, nor perhaps the mystery itself. H.

15: The Formula called “The Faith of Damasus”
15 We believe in one God the Father almighty and in our one Lord Jesus Christ the Son of God and in (one) Holy Spirit God. Not three Gods, but Father and Son and Holy Spirit one God do we worship and confess: not one God in such a way as to be solitary, nor the same in such wise that he himself is Father to himself and he himself is Son to himself; but the Father is he who begot, and the Son is he who is begotten; the Holy Spirit in truth is neither begotten nor unbegotten, neither created nor made, but proceeding from the Father and the Son, coeternal and coequal and the cooperator with the Father and the Son, because it is written: “By the word of the Lord the heavens were established” (that is, by the Son of God), “and all the power of them by the spirit of his mouth” [Ps. 32:6], and elsewhere: “Send forth thy spirit and they shall be created and thou shalt renew the face of the earth” [Ps. 103:30]. And therefore we confess one God in the name of the Father and of the Son and of the Holy Spirit, because god is the name of power, not of peculiarity. The proper name for the Father is Father, and the proper name for the Son is Son, and the proper name for the Holy Spirit is Holy Spirit. And in this Trinity we believe in one God, because what is of one nature and of one substance and of one power with the Father is from one Father. The Father begot the Son, not by will, nor by necessity, but by nature.
16 The Son in the fullness of time came down from the Father to save us and to fulfill the Scriptures, though he never ceased to be with the Father, and was conceived by the Holy Spirit and born of the Virgin Mary; he took a body, soul, and sense, that is, he assumed perfect human nature; nor did he lose, what he was, but he began to be, what he was not; in such a way, however, that he is perfect in his own nature and true in our nature.
For he who was God, was born a man, and he who was born a man, operates as God; and he who operates as God, dies as a man; and he who dies as a man, arises as God. He having conquered the power of death with that body, with which he was born, and suffered, and had died, arose on the third day, ascended to the Father, and sits at his right hand in glory, which he always has had and always has. We believe that cleansed in his death and in his blood we are to be raised up by him on the last day in this body with which we now live; and we have hope that we shall obtain from him either life eternal, the reward of good merit or the penalty of eternal punishment for sins. Read these words, keep them, subject your soul to this faith. From Christ the Lord you will receive both life and reward.
