This essay examines R. F. Taft’s role in the papal decision to recognize the Addai and Mari Anaphora a true eucharistic prayer, but even more so the pros and cons of this decision. The main obstacle was the position that exactly the Lord’s words “This is my body” and “This is my blood” are the sacramental “form” of the Eucharist. Yet, R. F. Taft showed that the (Roman) Catholic teaching does not mean that the transformation of bread and wine into the body and blood of Christ takes place exactly when these words are pronounced. It is more in line with tradition to hold that the transformation of the eucharistic gifts takes place because Christ himself pronounced these words on Holy Thursday and because, during the anaphora, prayers of thanksgiving, epiclesis and offering express the faith that the gifts are really transformed into Christ present in the sacrament.
