Did Protestants help design the new Mass?

Six Protestant observers — representing Lutheran, Reformed, Anglican, and Methodist communions — attended meetings of the Consilium that produced the Novus Ordo. They were observers, not voting members. They did not draft the prayers or set the rubrics. But to say they had no influence at all would be to flatter the historical record. Cardinal Bugnini himself acknowledged that ecumenical concerns shaped some decisions.

The most concrete evidence is structural. Several elements that traditional Protestants had long objected to were modified or removed: the offertory prayers explicitly invoking the Mass as a propitiatory sacrifice were rewritten along the lines of a Jewish meal blessing; many references to merits, satisfaction, and the priest’s personal offering were softened; the silent Roman Canon was reduced to one option among several, with new Eucharistic prayers composed in a more dialogic register. The new offertory was so close to a Reformed table-prayer in structure that some Protestant theologians of the time publicly remarked on the convergence.

Annibale Bugnini wrote candidly: the new Mass was shaped, in part, with an eye to removing “stumbling blocks” for Protestants. This was framed at the time as ecumenical sensitivity. In retrospect, it raises a serious question: a liturgy is the prayer of the Catholic Church, not a treaty document. Doctrines that distinguished Catholic worship from Protestant worship were precisely the doctrines defined at Trent. To soften them was, however unintentionally, to dilute them.

The blunter formulation — that Protestants designed the new Mass — overstates the case. The more accurate statement is that the Catholic architects of the new Mass took Protestant sensibilities into account in ways that affected the doctrinal expressivity of the rite. That is enough.
