@Kuvult – “there’s even a Rebbe in Tosfos named “Peter””
But let’s remember that Peter “the apostle” (l’havdil?) whose Hebrew name was ????? ???? was nicknamed in seforim “????? ??? ????” (PETER chamor).
[By the way, Peter is Greek for ???? (rock, or dome). Peter locked himself in a church on a dome for many years.
Some say that he was a tzaddik who was ???? ??? to distance Christianity from Judaism. According to some sefroim he actually composed many of the tefillos of Yom Kippur, including ???? ?? ??. Other seforim say that this is blasphemy.]
