In case anyone has forgotten, back in 2008 when Pope Benedict's Prayer for the Jews, for use in the Extraordinary Form Good Friday Liturgy, it was explained and defended by Cardinal Kasper, among others.
Cardinal Kasper's is a particular way of understanding the question of the conversion of the Jews. While I appreciate the sensitivies, I would not be comfortable with a blanket condemnation of 'targeted' evangelical outreach to Jews, as for example that taken by the Jewish convert Alphonse Ratisbon in the late 19th century. Cardinal Kasper does not make such a condemnation, but it might seem implicit in what he says. It is important, however, that he makes the point that we don't hide our witness to the Faith from Jews, and that our belief in the universal validity of Christ's redemption, and their rejection of this, has to be the basis of an honest dialogue.
If Cardinal Kasper has no problem with Pope Benedict's Prayer for the Jews, then it seems pretty surprising that anyone in the Church should have a problem with it.
