With Christ himself as the cornerstone
Absolutely - and still built on Peter by Christ, just as Jesus says.
This whole chain of argument is laughable. The “church” is a third century invention designed to replace Israel in the master plan of G-d. There is no such thing in scripture. The Nazarine never heard the word. He was a Jewish rabbi/prophet who lived entirely within the context of Torah Observant Judaism. He kept the Torah. Ate Kosher. Kept the Shabbat. Followed all the regulations regarding access to the Temple. He reaffirmed the eternity of the Taryog Mitzvoth. In short, he was not a Christian; He was a Jew. What got him in trouble was his passion to bring the burning flame of Torah to the entire world, to every nation. That’s what the “New Covenant is: the Torah, written on your heart.
