I am indebted to David Schutz for an article in an American magazine, apparently Jewish, called Tabletmag. The author is a Rabbi David Berger, who teaches in a Graduate School of Jewish Studies at Yeshiva University. It is highly intelligent, and an intelligent person will enjoy finding thought-provoking things in it with which creatively to disagree or even agree. (Notebook: Vatican II at 50: Assessing the impact of 'Nostra aetate' on Jewish Christian relations. December 15, 2015.)
Berger deprecates "the inappropriate dictation to others of what their own religion must teach", and goes on: " ... Jews active in interfaith affairs have not infrequently denounced the Christian belief that the entire world will recognise Jesus as the divine Messiah at the end of days. This, in my view, is none of our business, especially in light of the corresponding Jewish belief strikingly expressed in the High Holiday liturgy and the Aleinu prayer". (That particular "Christian belief" is of course precisely what S Paul teaches in Romans 11:25-26, and what Pope Benedict in 2008 took as the theme of his newly-composed Good Friday Prayer. Rabbi Jacob Neusner made a very similar point to Berger's some years ago in one of his own elegant defences of Joseph Ratzinger.)
He also reminds us that Maimonides, cited sometimes 'ecumenically' as a witness to a positive Jewish attitude towards the existence of Christianity, only saw it in a positive light as one step in the direction of the conversion of the whole world to Judaism, after which Christianity would be destroyed.
And, if I understand aright one of his faintly elliptic remarks, he delicately suggests that Christians who are anxious to describe Judaism as possessing a still salvific Covenant may accidentally be saying something rather embarrassing about the large numbers of Jews who do not live according to the Torah which expresses that Covenant (cfr. Ed Sanders' Covenantal Nomism). Had that thought occurred to you?
Berger thinks outside very many boxes!
As far as I can make out, none of the German or English bishops appears to have been in touch with Berger to explain to him how upset and confused he is by the Latin Prayer for the Jews used on Good Friday in the Extraordinary Form of the Roman Rite.
