That logic fails the moment we notice that "The Lord" quotes the OT Canon instead of "ignoring it because Jews rejected Jesus" .
The Lord quotes some texts from the Old Testament and does not quote others. There is nothing in his quotes to define the canon. He, for example, does not quote from a number of old testament books yet those books are received as canonical. The error in logic present in this discussion is that of making the Lord's use of texts into a test for canonicity. He never intended it to be so.
Paul and ever NT writer quotes it. Even the Orthodox and RCC quote the OT text.
The quotes in Paul's letters and in other New Testament books do not define a canon for the Old Testament and there is no indication in those quotes that the author is attempting to define a canon.
The Hebrew Bible is NOT in debate since all Christian denominations accept it as scritpure. The only thing we are debating about is what is NOT in the Jewish Bible - the OT.
The canon of the Old Testament within the Catholic Church has a long and complex history. The process of canonization, or determining which texts were considered inspired scripture, began in the Jewish community and continued in the early Christian church.
The Old Testament canon within Judaism was not fixed in the early period but it was recognized by the 2nd century BC that certain texts were considered authoritative and were set apart as sacred writings. The books that were included in the canon of the Jewish Scriptures were those that were considered to have been written by the prophets, and that were recognized as such by the Jewish community.
In the early Christian church, there was some debate and disagreement over which texts should be considered part of the canon of scripture. The canon of the Old Testament within Christianity was not definitively settled until the Councils of Hippo (393 AD) and Carthage (397 AD), where the canon of the Old Testament was established as the Septuagint version, which included several books not present in the Jewish canon, such as Tobit, Judith, Wisdom, Sirach, Baruch and 1 and 2 Maccabees. This canon was later confirmed by the Council of Trent in 1546.
The canon of the Old Testament within the Catholic Church is composed of 46 books, which include the 39 books of the Hebrew Bible and the seven books of the Septuagint version. These books are divided into four categories: the Pentateuch, the historical books, the Wisdom books and the Prophets.
It is worth noting that the canon of the Old Testament within Protestant denominations is not the same as the Catholic canon and includes only 39 books.
The idea that neither Christ nor the Apostles quoted from the OT since the Jews of Christ's day were in many cases disloyal fails to get out of the gate.
