Matthew 1:23 The Correct Meaning.
Berean Literal Bible
"Behold, the virgin will hold in womb, and will bring forth a son, and they will call His name Immanuel" which is, being translated, "God with us."
Matthew 1:23 is a quote from Isaiah 7:14 for Jesus as Immanuel who if followed will lead to salvation.
Then this concludes that (The God with us), is GOD the Father the only one true GOD, NOT Jesus.
As they are clearly NOT believing the countless scriptures teaching we are to believe GOD ALMIGHTY IS ONE and Jesus is TRULY the SON.
