re: #342 Nyet

Authentic in the sense that they contain historical truth, probably not. The Talmud does refer to Yeshu Ha-Notzri a number of times, including his death by stoning decreed by the Sanhedrin, which was probably a counter-reaction to the gospel narratives. (See e.g. Peter Schfer’s Jesus in the Talmud).

Those passages have been challenged by scholars as bogus. There were some satirical works dating to the 18th century, Toledot Yeshu and Hisronot Hashas containingn the alleged “missing parts of the Talmud” but those passages are not found in the actual Mesechte Sanhedrin.
