One more thing: Probably not proper to use AD to describe the goyishe calendar. It is roshei teivos for a phrase that includes recognition of some human as a deity. BCE for before common era and CE for common era is probably more appropriate. It jsut recognizes an accepted cheshbon without accepting any individual’s influence on its creation.
Unless it wasn’t a typo, and you were somehow involving the famous NASI apologist, though I can’t figure out why. 🙂
