Jesus could not have been God because he became a servant when he was incarnated, implying he was not divine before that.

In Philippians 2:5-7, Paul explains that Jesus existed in the form of God and chose to humble himself by taking on the form of a servant. This act of humility does not suggest that Jesus was not divine prior to his incarnation; rather, it indicates that he willingly set aside his divine status to fulfill his mission on earth. Furthermore, the concept of Jesus becoming a slave only at his incarnation rules out the idea that he was a created being, as angels are inherently servants. Therefore, if Jesus had been a created angel, he would have already possessed the form of a servant before becoming flesh, which contradicts the biblical narrative. Instead, Paul affirms that Jesus existed in God's form, thus maintaining his divine nature throughout his earthly ministry.
