Episcopal, IIRC . . . certainly NOT RC.
He started an entire thread about folks accusing FR of being anti RC. He was clearly not identifying as an RC on that thread.
Well, I could be wrong. But my memory and the post I found contribute to my continued belief he is Catholic. It is of no importance to me other than that I don't think this site is anti-Catholic. I am not Catholic, but I don't bash Catholics. I certainly disagree with them on some, to me, fundamental beliefs. But, so what?
If you can find the link to the thread you mentioned, I would be interested in reading it.
