Same God. No heresy.
In order to understand, do not relinquish your love for God, but remember your love for Him is to be a sacrificial love, not an adversarial reproaching judgment of what He provides.
God Bless.
My dear FRiend. You can say that all day long...but it doesnt make it so.
Did you not read the post? If G-d were a multiplicity of persons He would have said so...clearly...plainly...directly. At Mt Sinai, it was a National Revelation. He said...I HAVE NO FORM.
For Christianity to then 1500 years later say...guess what! G-d has a form! He is this god-man hybrid! Now...you must believe in him or else! Oh, and there is a 3rd person you must believe in too...god the holy spirit! And you must pray in the god-mans name! You must celebrate him by eating his flesh and drinking his blood! (just pretend though...unless your Catholic)....etc...etc
That makes G-d out to be a treacherous...duplicitous, liar. (G-d forbid). To give a nation a law they cant follow after telling them they can (Deut 30)....Tell them the Law is forever (Psalm 111 and many other places) when it is not forever...To tell this nation He is alone...when He is really three....To require no faith in a messiah for salvation...then to require it? What kind of god is that? It is not the G-d of my forefathers, not the G-d of the Jewish Bible...It is the god and god-man of the Grecco-Roman culture.
G-d Bless
