"I question, then, why Messiah didn't say such a thing to his followers...something like, 'Hey, stop going to the Temple, I've made the priesthood obsolete, you don't have to keep 95% of God's commandments, you can ignore God's Feasts, never mind about the food stuff, oh, and I've changed the Sabbath to Sunday. Happy Easter.'"
Internet debates are funny that way. :)
Shabbat shalom.
