How are you so mixed up then? lol
Yeah, Peter didn't understand--I agree.
Still, eventually, they went, so... what's your point?
They went to the nations and taught the nations to observe all things Christ taught them to observe--meaning that your nonsensical idea that "Oh, no, that was instructions just for Israel" is debunked.
Irrespectively, we're all baptized into Christ, all sharing in His bodily death and resurrection, thus are not in the flesh but in the Spirit (if the Spirit of Christ dwells in us), and we are His body and His body is His bride--it's all one faith in one truth of one Gospel (Gal 2)--so there's no basis for your poppycock divisions "church of Israel" and "church of body of Christ", because, again, if anyone would be in "church of Israel", but whom you categorize as being in "church of body of Christ", it's Paul, who was an Israelite and of the remnant being saved. Your placing him apart from "church of Israel" is just arbitrary nonsense--really, all of your structures are nonsense.
