Okay...and thank you!
However, since you have said "a God", it should be clear that just as is modeled in marriage (that "the two become one flesh"), the Oneness that these things portray is that of God and that Oneness that did and does again exist with the Father and Jesus. But I should think that since you also mentioned Jesus' pre-existence where He shared the same glory as the Father, that you know this.
All of which says two things:
- That Jesus' pre-existence of, and now again sharing the same glory, refers to them being One God.
- And, that Jesus' short time as having "become flesh" and separated from God (as we also are for a time), does not make Him not God, but rather [in addition to] being God, also makes Him a man...because, for the sake of salvation He was [also] a man for a time. Which definition of Oneness is confirmed in the scriptures as God being "all in all"--that is, that all is "in Christ, in God", meaning all in God.
When I said “a God” I was referring to “the one God”, his God and my God, the Father alone, Yahweh.
I don’t agree with your premise that Yahweh shared his glory with Jesus. The glory which Jesus had with Yahweh was nothing more than glory in prospect.
