Augustine of Hippo
Reflecting on the preceding thoughts, a hymn arises, and praise be to the Lord God of Israel. For the promise made to the childless woman is realized, and He who has redeemed you, O God of Israel, will be recognized by all peoples. Isaiah 54:5 He alone performs wonders, for whoever acts in His name is engaged in His divine work; He solely brings forth miraculous deeds.
Anyone who delves deeper into the words of Christ, where He states, 'If I had not done in them works which no other man hath done,’ will realize that it is indeed He who accomplishes these deeds, even if a man of God performs anything resembling them. He possesses the ability to effect all things through Himself, yet no one can achieve anything apart from Him. For Christ, along with the Father and the Holy Spirit, constitute one God, as it is proclaimed, ‘Blessed be the Lord, the God of Israel, the only One who works miracles!’ (Psalm 71:18). Therefore, no one else performed such wonders among the Jews; any other individual who exhibited such acts did so by virtue of what He was enacting within them. He alone achieved them without the need for their involvement.
