I know you are sola scriptura. That is why I was very, very surprised to see you quote a non-scriptural reference in anything in our discussions (anyplace, not just here).
The Talmud is a collection of Jewish rabbinical teachings. And the funny part about it is that it was compiled after the New Testament was compiled (yes I know it represents oral teaching that is far more ancient, but...)
The bit about the Matzos and the wine cups that you cited (a/k/a the Seder) comes from the Talmud. Specifically tractate Pesahim in Seder Moem.
I do not think you know what sola scriptura means..
