Unable to define? Are you retarded? I think you're unable to comprehend and that's the problem. You're the fool who doesn't see his own foolishness and considers anything he doesn't understand to be nonsense. But I'll spell it out for you, fool. Christianity IS Judaism. They are the same. And Christianity is just as foreign to European spirituality as is Islam and Judaism. Yeshua ben Yosef was a Jewish Messiah for Jewish people and explicitly said so - Goyim not included.
