There are several revivalist movements within Rabbinic Orthodoxy, to return to earlier forms of Judaism, i.e. to be as authentic as is possible. These can be viewed sometimes in specific groups, rather than universally. Some examples include:
Zionism: Returning to Israel after exile. This includes various Mitzvot that can only be fulfilled in Israel, e.g. Shemitta.
The Sanhedrin: There is a group who have set up a Sanhedrin, which is the name given to the Rabbinic high court that existed some 2000 years ago.
Tekhelet: The use of a special blue dye on one strand of tzittzit, according to the Talmudic identification of particular mollusc from which the dye is taken.
Army: Whilst the Ultra-orthodox do not wish to participate in the Israeli army, some Zionist orthodox see it as a Mitzvah from the Torah.
Temple Mount: Again, disputed by Ultra_Orthodoxy, but many in the modern and Zionist orthodox will want to go up to Temple mount to begin the process of prayer and potentially the temple.
These are now physically possible, some will still need more development, e.g. sacrifices and building the Temple.
There is one particular movement which, according to my manifestation, can never be revived. That is the Oral Law. This needs clarification, after all, do not all Rabbanites accept , study, and practice the oral Law? Actually, they do not. They have a second written law in the form of the Talmud. It is encoded on paper, and hence is not "oral" in the sense of how the actual Oral Law is claimed to have been transmitted.
Of all the revival movements, why are they unable to revive the oral law as they claim it was originally? After all, the Talmud says one who puts the Oral Law on paper is as if he has burned it.
So what is preventing them from practicing, teaching, and transmitting the oral law orally?
I challenge the Rabbanites to try this, and see how successfully they can transmit the oral law orally.
Could a yeshiva educate students in this fashion, without resort to books?
