Yeah, Russell was a bit Eurocentric and lacked quite heavily on Biblical knowledge.
Everyone knows the land of Canaan was in the Middle East, not Africa. Is Israel in Africa? No. And 2 of Israelite tribes were part Egyptian (Africans); the 2 sons of Joseph. [No Arabs in Africa back then]
Whenever Israelites including Abraham, Mary & Joseph, et al needed to hide from crazies, they always fled to Africa. That's pretty much where the always went.
But Russell was a man of his times and held beliefs consistent with his baptist/protestat past and general US American rascist thought. Not to mention it was an erroneous teaching of the RCC for centuries.
I chalk that up to RCC envy. No one saught refuge in Europe, not ever. Under persecution, Christians saught refuge in Egypt and Turkey.
