Christians, Protestant and Catholic, celebrate the Lord's Day on Sunday. It seems to me Protestants would rather shoot their dog than follow Catholics if it "ain't in Scripture."
My alignments are well known here.
Not by me, but don't bother, I'm not the least concerned with which particular mix of Judaism and Christianity you've decided is scriptural. Take Sunday up with the Protestants on the thread; they're much more into that sort of do your own thing thing.
You are completely wrong, of course...There are plenty of things not in the scriptures that we embrace...
But when it comes to following a religion that is condemned by scripture, and has traditions that contradict scripture as does your religion, I'd not only kill my dog before I accepted it, I'd serve him up as a canine casserole...
