Matthew 1:23 "Behold, the virgin shall be with child, and shall bring forth a son. They shall call his name Immanuel;" which is, being interpreted, "God with us." - World English
The above scripture is often quoted by trinitarians without any explanation as to how this verse is supposed to mean that Jesus is a person of "God". What the verse does not say is "Jesus is God with us," as many seem to assume upon the words. Nothing is said about God existing as three persons. Rather it says that they will call the Anointed One's name Emmauel (Immanuel), and that the name means, "God with us."
The scriptures show that "God" (one person, not three persons) was "with" Jesus. Peter spoke of "Jesus of Nazareth, how God anointed him with the Holy Spirit and with power, who went about [in the days of his flesh -- Hebrews 5:7] doing good and healing all who were oppressed by the devil, for God was with him." (Acts 10:38, World English) Peter used the word "God" twice while speaking of Jesus. He first stated how "God" anointed Jesus. Earlier Peter stated: "God has made him both Lord and Christ [meaning, anointed one], this Jesus whom you crucified." (Acts 2:36) Was it three persons that anointed Jesus, or was it one person? Isaiah quotes the Messiah prophetically as stating: "Yahweh has anointed me." (Isaiah 61:1, World English) This is the same Yahweh who proclaimed Himself to be "the God of Abraham, Isaac and Jacob." (Exodus 3:14,15) The unipersonal God of Abraham, Isaac and Jacob speaks and performs His works through His son. — Deuteronomy 18:18,19; John 3:34; 5:19; 6:38; 7:16,28,29; 8:28,38,40; 12:29; 14:10; 17:8; Acts 2:13-26; Hebrews 1:1,2.
But Peter also said, speaking of Jesus while in the days of his flesh: "God was with him." (Acts 10:38) Again, it is a unipersonal God that Peter speaks of who was with Jesus. However, the fact that "God was with him," and the fact that Jesus was with Israel, demonstrates that God, being with the one whom He anointed, was also with His people Israel through Jesus' presence. However, only a few recognized Jesus for who he really was. -- John 1:10-12.
There is no reason to add to the scriptures dogma that would make Jesus a person of the Most High, or any teaching that Jesus is the Most High.
