The "*" is to prevent spelling the name of a false "gxd." Most Jews and Noachides write "X-tians" and "X-tianity," but I don't because I feel that is a legitimate abbreviations for chr*stians themselves to use (when taking notes in a class or something) and I don't think they should have to feel guilty about it ("X" being the Greek letter "chi").
I mean that American chr*stians want the Jerusalem Temple rebuilt and the ancient Biblical sacrifices to be restored, while more traditional chr*stians think that would be a terrible thing.
On Sukkot (which begins tonight) ancient Israel would offer seventy sacrifices on behalf of all the non-Jewish nations. My your nation and mine be worthy of a year of peace and redemption!
