John XXI was a very great pope and he's the one who actually corrected the liturgy. He did so because of his friend Jules Isaac, a French Jewish historian who was a friend of John Paul, of John 23rd, and he convinced him and he changed the liturgy, no more Jew, the perfidious Jew and so forth and now, and don't speak any more of the Jews killing Christ. Things have changed.

Whether every story that's there [in the Bible] is a historic truth ... Again, I'm not concerned.
