Ah, I suppose you are right. But the Ethiopian stands for a random person who lives in let’s say sub Saharan Africa or some other place, and hears about Jesus and rejects it. Does that mean that group of blacks is Jesus’s own people? Of course not. The Ethiopian is interchangeable with any non Israelite.
I'm talking about the one that got baptized, who would have been white, otherwise it creates a conflict in Scripture, since God never knew any family besides Israel
