As I mentioned above, we both eat and drink when we recieve a single species.
Our mouths decieve us, in sensing only eating, in much the same way as our eyes see only bread.
Remember that the Chuch regularly withheld the chalice from the laity, but the Church cannot violate a commandment of Christ. It has always followed this commandment, giving the faithful the Blood of Christ to drink. But it did so under the species of bread.
One other thing, we cannot take the Eucharistic Narrative as always applying to the laity. Christ followed his statement of “take and drink” with “Do this in memory of me”
The Church has held that as a command for the priesthood to celebrate the Eucharist regularly and as a memorial.
But if one takes the Eucharistic Narrative as applying equally to the laity, it would me we all can celebrate Mass. Does anyone here wish to make that claim?
