One of the Popes (a REAL Pope, unlike today's facsimile) called the Jews "Our beloved elder brethren".
Yes. I think it was John XXIII, who introduced himself to a group of rabbis with the Biblical words „I am Joseph, your youngest brother“ (his birth name had indeed been Giuseppe i.e. Joseph).
And I know that he made grave mistakes with the Second Vatican Council, but OTOH he is responsible for saving the lives of many Jews in 1944 who were stranded in Turkey🙂
