Romans 11:33-36
O the depths of the riches of the wisdom and of the knowledge of God! How incomprehensible are His judgments, and how unsearchable His ways! For who hath known the mind of the Lord? Or who hath been His counsellor? Or who hath first given to Him, and recompense shall be made Him? For of Him, and by Him, and in Him, are all things: to Him be glory for ever. Amen.

Verse 33-36. O the depth, &c. After he hath spoken of the mysteries of God’s grace and predestination, of his mercy and justice, which we must not pretend to dive into, he concludes this part of his epistle, by an exclamation, to teach us submission of our judgment, as to the secrets of his providence, which we cannot comprehend. — How incomprehensible are his judgments, &c. — Who hath first given to him, and recompense shall be made him? That is, no one, by any merit on his part, can first deserve God’s favours and mercy, by which he prevents us. — For of him, from God, or from Jesus Christ, as God, and by him, who made, preserves, and governs all things, and in him, is our continual dependance: for in him we live, we move, and exist. In the Greek, it is unto him, to signify he is also our last end. See the notes, John c. i. Wi. — All things are from God, as their first cause and creator; all things are by God, as the ruler and governor of the universe; and all things are in God, or (as the Greek has it) for God, because they are all directed to his honour and glory. For the hath made all things for himself. Ps. xvi. S. Basil, lib. de Spiritu sto. c. 5.

343: Symbol of Faith
ST. LEO IX 1049-1054 From the epistle "Congratulamur vehementer" to Peter, Bishop of Antioch, April 13, 1053
For I firmly believe that the Holy Trinity, the Father and the Son and the Holy Spirit, is one omnipotent God, and in the Trinity the whole Godhead is co-essential and consubstantial, co-eternal and co-omnipotent, and of one will, power, and majesty; the creator of all creation, from whom all things, through whom all things, in whom all things [Rom. 11:36] which are in heaven or on earth, visible or invisible. Likewise I believe that each person in the Holy Trinity is the one true God, complete and perfect.
