Canaanites are Semites. They were condemned for their pagan practices, but they, like the Phoenicians were of the same fold as the Israelites.
Samaritans are also Semites. Their religion is Judaism.
And you neglect, "Go and make disciples of all nations, baptizing them in the name of the Father, and of the Son and of the Holy Spirit."
No I don't. It was mentioned earlier in another post to FK. The word for 'nations' is not by any stretch a word that applies to all nations by necessity. It means 'tribe,clan' and in the NT context is used for the descendent's of Jacob and Isaac.
you forget Philip's baptism of the Ethiopian eunuch, while Paul was as yet, Saul, the persecutor of the Church
Anyone could convert to Judaism just as anyone can do so today. No one had specific isntructions to preach to the Gentiles.There was no reason for it. The messianic belief was all about Judaism.
+Paul changed his name from Saul to +Paul after he baptized Paulus, a Roman governor (I believe on Cyprus).
No, they were pagans that the Assyrian king relocated. You, like them, know not what you speak of.
Sure, you can gloss 'panta ta ethnE' as 'all the tribes' , or go full out and give it its Attic sense of 'all the companies of men'.
The problem for you position is that, throughout the LXX, 'ta ethnE' used as a translation of goyim, and usually Englished as 'the nations' or 'the gentiles'.
Get out your Greek Old Testament and read Psalm 1, and there it's sometimes Englished at 'the heathen'. Never have I seen Psalm 1 translated "Why do the tribes rage. . ."
The Great Commission, read using the Greek the way it is used throughout the Scriptures, is explicitly a command to convert and baptize the gentiles.
And Semitic or not, the Canaanites were the gentiles ne plus ultra!
And you are wrong: the reason the detail of the Ethiopian court offical being a eunuch was important: eunuchs could not convert to Judaism.
