I don’t know if it’s valid or not; the only thing I do know with certainty is that John Paul II’s approving it means absolutely NOTHING. Here’s why I say that: Both John Paul II and Cardinal Ratziner approved, as valid, a “mass” that has absolutely no words of ocnsecration at all. Every single one of them is missing, yet they claim that the so called “mass” is valid none-the-less.
I assume you mean the Anaphora of Addai & Mari? Perhaps this will clear things up a bit:
"The doctrinal question before the Pontifical Council is whether the incoherent verbal form of the anaphora’s Institution Narrative retains the substance of the sacrament. The Council decides that the “the words of the Institution are not absent in the Anaphora of Addai and Mari, but explicitly mentioned in a dispersed way, from the beginning to the end, in the most important passages of the Anaphora.” [Emphasis added.] Thus the Council upholds the traditional requirement that the words of Institution must be explicitly present in a valid Eucharistic Prayer. The oddity of the Anaphora of Addai and Mari is that these words are dispersed throughout the liturgy, but are nonetheless explicitly present. "
"In the Anaphora of Addai and Mari, the Institution Narrative is dispersed throughout the Liturgy, rather than concentrated in one place. However, we will find that it contains the same essential verbal elements of the valid rite of Pope Sixtus. One of the anaphora’s central prayers opens:
O my Lord, in thy manifold and ineffable mercies, make a good and gracious remembrance for all the upright and just fathers who were pleasing before thee, in the commemoration of the body and blood of thy Christ, which we offer to thee upon the pure and holy altar, as thou hast taught us.
This explicitly indicates that the Body and Blood of Christ are being offered to the Lord as an altar sacrifice. The phrase “as thou hast taught us” can only refer to the Last Supper discourse. Although the words of Jesus’ discourse are not recited, they are expressly referenced in this prayer, which claims to act in accordance with our Lord’s command to commemorate His sacrifice. Elsewhere, the anaphora removes any doubt as to the meaning of this sacrificial offering:
Glory to you, my Lord, for you have called me, even feeble me, in your grace, and have brought me near unto you in your compassion, and have established me as a designated member in the great body of your holy catholic church, to offer before you this living, holy, and acceptable sacrifice, which is the memorial of the passion, death, burial, and resurrection of our Lord and Savior, Jesus Christ, - through whom you were well-pleased and reconciled to forgive the sins of all men.
And as another example:
*
"…as in the Anaphora of St. Xystus (Pope Sixtus II)…This ancient Eastern Orthodox liturgy, attributed to a Pope(!), omits all of the words of Christ at the Last Supper, save His admonition to do these things in remembrance of Him. Nonetheless, this Institution Narrative retains what is essential, explicitly declaring that the blessed bread is now “His propitiatory Body for life eternal”, and the content of the cup is now “His propitiatory Blood for life eternal.” These words, in the context of a liturgy that clearly intends to consecrate the bread and wine as the Body and Blood of Christ as a sacrifice for our sins, constitute a valid Institution Narrative. The priest acts in persona Christi not by reciting Christ’s words in the first person, but by performing the same act of consecration that Christ performed at the Last Supper. *
Apparently, the validity of any rite is not solely based upon any one particular set of words. Consider this comment carefully, "
The priest acts in persona Christi not by reciting Christ’s words in the first person, but by performing the same act of consecration that Christ performed at the Last Supper." A valid consecration is not based upon saying the “magic words” but by "
performing the same act of consecration that Christ performed at the Last Supper."
Finally, here is another interesting fact that deserves consideration: "
A study done by Dom Leclerq finds that there have been no fewer than 89 variations in the formulas for consecration in the history of the Church. (Whitehead, 109, Dom Leclerq, Dictionnaire d’Archeologie Chretienne et de Liturgie (Col. 730-750).
Would you suggest that these variations in consecration formulas render any Mass invalid because they don’t explicitly use “for many?” In any event, it is very dangerous ground to suppose that a pope’s approval of a Eucharistic liturgy “means absolutely NOTHING.” As the Vicar of Christ he holds a unique position where things he "
holds bound on earth are bound also in heaven, or loosed on earth are loosed in heaven." Are you going to presume to judge the authority of the pope?
