Now the birth of Jesus Christ took place in this way. When his mother Mary had been betrothed to Joseph, before they came together she was found to be with child from the Holy Spirit. (Matthew 1:18 ESV)
I've heard it argued by Trinity deniers that if you believe that God the Father was Jesus' Father then why does it say that Mary was with Child from the by the Holy Spirit.
there presuppositions have guided their interpretation though. They assume that Jesus didn't exist before his incarnation but God the Son was always with God the Father in eternity past.
In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God. (John 1:1-3 ESV)
They simply overlook that Jesus was Eternally the Son with the Father in all of eternity and the Holy Spirit simply brought about Jesus' incarnation in the flesh.
