Since the Holy Spirit birthed Jesus, the last phrase in this verse could be rendered: the Son of the Holy Spirit. -> God is the generic term for divinity. ->  God is Spirit  Joh 4:24. -> Therefore Divinity is Spirit.   -> The supreme divine Spirit is the Holy Spirit -> Christ Jesus is the image of His Holy Spirit. -> Jesus is God. Isa 9:6 Joh 20:28 Mat 1:18
