I had heard this alleged before, is this in the Talmud?
This is nothing. There are many parts of the Talmud that would horrify any decent human being, nevermind Christians. I won't post such here because it's truly hard to read and doing so would be unfair to the majority of Jews who don't attach themselves to such nonsense.
That being stated, does it somehow surprise you that the Jews - who gave us our Redeemer - completely reject him? Why do you think our Church used to pray for them? Ending this practice was an act not of charity but of contempt.
It used to be doctrinal to love and pray for them, now unfortunately it's doctrinal to completely ignore them.
BOOO!
My comdolences to you on the loss of your Pope Pol I.
Hope all's well.
