P.S. (and of course it will have to wait till after you’ve enjoyed the Sabbath for you to see this... I’m a gentile though [but with a lot of background in Judaic thought] so it’s not even obligatory on me by any covenant, remember...)
If you’re hinting at the old canard that the Christians moved the sabbath to Sunday, just toss that idea out.
First, not even all Christian groups, despite being overwhelmingly gentile today, do this. Ever heard of the Seventh Day Adventists? Although gentile, they still honor a Saturday sabbath. And they are blessed for it, too, even though no law requires they do what they do. They do it out of love for God.
Second, Jewish Christian groups honor a Saturday sabbath. It remained a New Testament norm. Check the gospels.
You’re probably thinking of a Roman Catholic doctrinal move. I’ve got severe problems with a lot of Roman Catholic teachings. It doesn’t mean Roman Catholics can’t be Christians. The essence of Christianity is in the covenantal relationship with the Christ, as the essence of Judaism is in the covenant with Abraham. The Christian promise of permanent salvation (though woefully blasphemed by Catholics — here’s where Calvinist denominations, and even the Seventh Day Adventists, really shine) corresponds to the permanence of Jewish identity by the bloodline of Abraham and Sarah (or later conversion by choice).
Yes, we crazy Christians identify it as a better covenant.
I am curious why we need to turn a thread about Chabad trying to make irreligious Jews better Jews into a debate on Christianity vs. Judaism.
