The Priest does not always receive under both kinds. If for some reason he cannot celebrate Mass, yet desires to receive Holy Communion, he receives under the form of bread only, just as any other communicant. If he celebrates Mass, he must consecrate both kinds for the sake of the Sacrifice, the separate consecrations being necessary for the representation of Christ’s death by the shedding of His blood on the Cross. Having consecrated under both kinds the Priest must consume both kinds. But even in doing so, he receives no more than the laity, for both Priest and lay communicant receive the complete Christ, and more than the complete Christ cannot be received. But your objection proceeds from a complete misunderstanding of the nature of the Eucharist. The idea of the officiating Priest having a “drink of wine” which is denied to the laity does great injury to the reverence due to the Presence of Christ, and is utterly absurd. About an egg-cup full of wine is used in the celebration of Mass, and in any case if a Priest did merely want a drink of wine there is no need for him to vest himself elaborately and spend half an hour saying Mass in order to have it.
