This is the Problem:
There are significant differences between the two Talmud compilations. The language of the Jerusalem Talmud is Jewish Palestinian Aramaic, a Western Aramaic dialect which differs from that of the Babylonian. The Jerusalem Talmud is often fragmentary and difficult to read, even for experienced Talmudists.
The Babylonian Talmud is much more widely studied than the Jerusalem Talmud. Furthermore, if there is a disagreement between the two talmuds, the halachah (Torah law) follows the Babylonian Talmud.
The simplest explanation for this: The redaction of the Jerusalem Talmud was forcibly interrupted in the mid-fourth century when the Romans suppressed Jewish scholarship in Israel and most of the Talmudic scholars fled to Babylon. The redactors of the Babylonian Talmud, on the other hand, were able to thoroughly review the Talmud and present us—about 150 years later—with a finished product, which became accepted as the final word in Jewish law and tradition.
So if the Babylonian Talmud is darkness, written in the darkness of exile, while the Jerusalem Talmud was written in the light of the Holy Land, closer to the time of the Temple, why do we choose darkness over light?
Therein Lies the Problem.
Funny the Roman church has their hands in this? Pope
