Actually, it seems that “the Church” has approved these as valid, unless conclusions of the Congregation for the Doctrine of Faith which are approved by the pope are not authoritative enough.
This is from “The Guidelines for Admission to the Eucharist between the Chaldean Church and the Assyrian Church of the East” issued by the Pontifical Council for Promoting Christian Unity:
As for the Cardinal Ratzinger quote that a Mass without the words of consecration cannot be valid, the Church seems to have resolved this issue in regards to the Anaphora of Addai and Mari in this way (also from the above-quoted guidelines):
But the fact remains that you won’t find the words of consecration in any *recognizable * (i.e., “This is my body”…“This is my blood”) form in these Eucharistic prayers.
