That touches on the real issue. If the authority of Judaism was passed to the Church instead of to the rabbis, then it would seem that one must accept Mariology and the Papacy and other accoutrements of Catholicism. There is no coherent religion without some kind of authoritative tradition, which is why intellectuals who become believing Christians tend to choose Catholicism.
A small angle of error at a close target becomes much more obvious at longer distances.

The authority of Judaism is up for them to decide. I am not Jewish. However, once Christ founded a Church and that Church was led by Apostles, then those who followed, i.e. Bishops, then it was the Church who would decide what was canonical for Christendom, not the Jewish Scholars of the late 1st and 2nd centuries.
For those Jews who became Christian, it was the Church and its authority that decided the canon of the Bible, for those Jews that did not become Christian, it would be the Jewish Rabbinical scholars of the 2nd century, etc. Clearly by that time, as evidenced by the debate between Saint Justin Martyr, and orthodox Church Father, and Trypho the Jewish Scholar, there was a divergence on the OT translations in the 2nd century. Justin shows the Church’s acceptance of the LXX [Greek] version of the OT as the standard text, the Jews of the 2nd century Hebrew texts that seemed to have been revised are down around the same time.
