Yeah…it is a statement that may not be technically heretical in and of itself…BUT it is (in the world of Clement X’s
Unigenitus):
“captious, evil-sounding, offensive to pious ears, scandalous, pernicious, rash, injurious to the Church and her practice, insulting not only to the Church but also the secular powers seditious, impious…suspected of heresy, and smacking of heresy itself, and, besides, favoring heretics and heresies, and also schisms, erroneous, close to heresy,”
The Priest acts in persona christi and confects the sacrament. He doesn’t need us, he could do it alone. Only the deacon, perhaps, as an ordained minister…can be considered as “cooperating” in a unique way (like Mary’s unique cooperation with Christ on the cross). But the sacramental power flows from the hands of the priest and he certainly doesn’t* need *the deacon, nor the congregation.
He doesnt “lead the assembly in praying the eucharistic prayer”…he PRAYS the eucharistic prayer and we join with him. We can unite our hearts and intention to his prayer, but it is still his Sacrafice in terms of Active Participation.
And the epiclesis isnt even the words of consecration (at least not in the west) so I don’t know what this book was thinking. Get far away from it.
The Catholic Encyclopedia’s article on Laity says (though this was pre-Novus Ordo…the essence of the ordained ministry and sacraments hasnt changed):
As to Divine service, the liturgy and especially the essential act of the Christian worship, the Holy Sacrifice, the active ministers are the clergy alone. But the laity really join in it. Not only do they assist at the Sacrifice and receive its spiritual effects, but they offer it through the ministry of the priest. Formerly they could, and even were obliged to, bring and offer at the altar the mater of the sacrifice, i.e. the bread and wine; that is what they really do to-day by their offerings and their stipends for Masses. At several parts of the Mass, the prayers mention them as offering the sacrifice together with the clergy, especially in the passage immediately after the consecration: “Unde et memores, nos servi tui (the clergy) sed et plebs tua sancta (the laity) . . . offerimus praeclare Majestati tuae, de tuis donis ac datis”, etc. The laity reply to the salutations and invitations of the celebrant, thus joining in the solemn prayer; especially do they share in the Holy Victim by Holy Communion (confined for them in the Latin Liturgy to the species of bread), which they can receive also outside of the time of Mass and at home in case of illness. Such is the participation of the laity in the Liturgy, and strictly they are limited to that; all the active portion is performed by the clergy.
