The quote says,
I count among the most important results of the ecumenical dialogues the insight that the issue of the eucharist cannot be narrowed to the problem of ‘validity.’ Even a theology oriented to the concept of succession, such as that which holds in the Catholic and in the Orthodox church, need not in any way deny the salvation-granting presence of the Lord [Heilschaffende Gegenwart des Herrn] in a Lutheran [evangelische] Lord’s Supper.
Since the context is validity, and since he believes that John 6 says we must eat His flesh, etc., it seems the real presence is what is meant by ‘salvation-granting’. That said, I suspect that there would be, in his thinking, nuances that would confirm the CC belief in a “difference” of some sort between this and a Catholic Eucharist.
