Billy Graham's quote at the top of the page is without reference, and we don't actually know its context. He could have made that comment about any issue. It's also not disclosed with the text that follows. I think that if you are bold enough to quote him, you should be honor him by giving a reference, and following it up in the post.
I found the full quote on the Internet, from an interview Rev. Grahm did with McCall's magazine in 1978:
I am far more tolerant of other kinds of Christians than I once was. My contact with Catholic, Lutheran and other leaders--people far removed from my own Southern Baptist tradition--has helped me, hopefully, to move in the right direction. I've found that my beliefs are essentially the same as those of orthodox Roman Catholics . . . We only differ on some matters of later church tradition.
