Actually yes it would.
I’m a Jewish monotheist, not a trinitarian. My answer would provide you with how a Jewish monotheist who believes Jesus is the Messiah understands the incident. That is education about Jewish monotheism, not education about the Trinity.
If Jesus is God. and as we have seen, the HS (a seperate entity) is God.
well the trinity is confirmed.
I agree that Jesus is God and the Holy Spirit is God. That doesn’t confirm the Trinity.
As I mentioned earlier in this thread, even the largest branch of unitarianism - of which I’m not a part - agrees that Father, Son and the Holy Spirit is the one God.
It does not matter what historical words of men say.
Would you be in favor of rejecting the trinitarian creeds?
