NO reference whatsoever to The Father in 9:5. It's all about Christ, God over ALL, blessed forever.
Romans 9:4 refers to God, BUT NOT to any specific Person.
Romans 9:4-5... Who are Israelites; to whom pertaineth the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises; Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen.
1) Does “God” in Romans 9:4 have ANY reference whatsoever to The Father?
2) Does “God” in Romans 9:5 have ANY reference whatsoever to The Father?
I say Yes and Yes.
IMO, if you answer Yes to one but No to the other, that would mean “God” in one verse is DISTINCT from “God” in the other verse.
Here is an overview of what I believe...
GOD is spirit and is the only one who is eternal. GOD is also in the universe as spirit and as a human. GOD in the universe as spirit is called the Spirit of God, GOD in the universe as a human is called the Son of God, and eternal GOD is called God the Father.
