“So, besides the obscure letter which contradicts another letter written by the same person, could you please provide Traditional Catholic teaching that supports Lumen Gentium/Nostrate Aetate re: Islam/Muslims?”
Look it up. Use the internet. Try.
Oh I have. I have been researching the errors of Vatican II for a couple of years now. I have found no Traditional Catholic teaching to support Nostra Aetate nor Lumen Gentium regarding Islam and Muslims (although I have found much to contradict NA and LG).
The point was to have you offer up the Traditional Catholic support since you're the one who is so sure that Lumen Gentium and Nostra Aetate do not teach novelties regarding the Muslim religion. But I see you don't have any such support either. And that's all I really needed to know...thank you.
