Real presence
The Holy Eucharist is the doing in the sensible world, by God’s appointment under material forms, what Christ our Head and Chief is ever doing in the spiritual world. There is an earthly altar, and a human priesthood, and bread and wine; but Christ is really present as priest, and offering, and the food of the faithful who feed upon the sacrifice. One would expect that since Christ is in the Eucharist as priest and offering.
