Regarding the Christian/European Church censoring parts of the Gemorah, are any of the parts of the Gemorah that were forcibly deleted by the censors completely lost to us today or do we, essentially, know all the missing passages?
The question is interesting because the Gemorah originated outside of Christiandome and the Gemorah always was present outside of Christian lands. So it would stand to reason that regardless of what the Church censored, Klal Yisroel always had and never lost the uncensored version of the Gemorah.
