I have, over the years, offered quite a few tests (smaller or larger) for quickly checking the reality or the orthodoxy of men who claim to be “Christian”. Here is another (just one question this time):
‘Would it be per se immoral to genocide Muslims, that are raping and murdering our sons and daughters?’
A Christian will say — at the very least — that it is morally permissible to do so.
A good Christian will say that it is morally obligatory.
