Considering that christians are a break away group from the Jews, that would make the christians the heretics and apostate. ;)
Not exactly. This isn't a doctrinal dispute - it's a question of fact. The Messiah either "did" or "did not" come. If He "did" than Christianity is the original core and jews "broke away" from the Truth. If He "did not" then the Christians are heretics. Not all breaks mean that the older is the core and the newer is the apostate group (until the 1300's... THEN the rules changed..:-)...)
