since the bible must never, ever be interpreted literally (except for "this is my body, this is my blood").
There you go again. You have, once again, made a false statement of Catholic belief. Are you deliberately trying to trash your own credibility?
How about "nothing in the first eleven chapters of Genesis must ever be interpreted literally?" Is that better?
You know, as much as I disagree with Sister Flaky, I can at least understand her. Catholics who claim to believe in the "Biblical Adam," yet who insist none of the details about him recorded in the Bible can be assumed without "imposing one's private interpretation on the text," on the other hand, would probably strike Sister Flaky as inconsistent (as they do to me).
At least Sister Flaky and I are logical.
No. Even that is false. As I have told you several times in the past, If Joe Catholic reads Genesis 1-11 (or any other part of the Bible) in the strictly literal sense that you prefer, he is perfectly welcome to do so. His reading of Scripture is perfectly in line with the teaching of the Church. If Father Flake or Sister Silly tell him otherwise, so much the worse for FF and SS: they are mired in heresy. Deal with it.
