OK, there are risks in Liturgical Restoration. Introduce a prime-time Vetus Ordo on Sunday morning, and it's always possible that a misguided group will get in touch with the Tablet and, before you know where you are, the local auxiliary bishop will be knocking on your door. Or even celebrate the Mysteries facing in the same direction as the People of God, as commended by the considerable authority of Cardinal Sarah, and some people may react as if the End of the world is imminent.
But there is one thing that a priest can do with relative impunity. Use the Roman Canon. Use it invariably. Say Good Bye to all the other, phony, 'Eucharistic Prayers' and stick to the only authentic Roman EP, EP1.
The IGRM says that this is the only EP which 'may always be used'.
If anybody does want to know why you have adopted this practice, the explanation is simple.
(1) This is the only ancient Roman Eucharistic Prayer.
(2) It is much more ancient in its theology than any other EP.
(3) For example: it displays the ancient idea that the Bread and Wine are transubstantiated into the Lord's Body and Blood simply by being accepted by the Father (see the prayer Quam oblationem). All the later prayers appear to operate on the unRoman assumption that the Father, in response to the prayer of the Priest, sends the Holy Spirit down from heaven onto the bread and wine so as to change them. Thus, even if they appear in a volume labelled ROMAN MISSAL, they are not 'Roman' prayers.
