Quotation from the Formula on the role of the Resurrection and the Two Natures in Christ:
16 11. Christ always had this majesty according to the personal union. Yet He abstained from using it in the state of His humiliation, and because of this He truly increased in all wisdom and favor with God and men. Therefore, He did not always use this majesty, but only when it pleased Him. Then, after His resurrection, He entirely laid aside the form of a servant, but not the human nature, and was established in the full use, manifestation, and declaration of the divine majesty. In this way He entered into His glory [Philippians 2:6–11]. So now not just as God, but also as man He knows all things and can do all things. He is present with all creatures, and has under His feet and in His hands everything that is in heaven and on earth and under the earth, as He Himself testifies [in Matthew 28:18], “All authority in heaven and on earth has been given to Me” [see also John 13:3]. And St. Paul says in Ephesians 4:10, “He … ascended far above all the heavens, that He might fill all things.” Because He is present, He can exercise His power everywhere. To Him everything is possible and everything is known.
