My friends response was in a conversation where I said that Christ went to Sheol and preached to the captives and then led them to Paridise. ... Unless I'm way off base, these things were discussed by Church Fathers somewhere. I just figured there would be a book somewhere - hopefully in English - that I could point to without depending on my opinion. Cause we know where our opinions come from, don't we.
