The doctrine of the Holy Eucharist consist of that of the Eucharist sacrifice, the sacrificial meal, and the sacrificial food, or to express it otherwise, it consists of the doctrine of the Mass, of Communion, and of the Real Presence. There is no presence of Christ in the Blessed Sacrament that is not meant first and foremost as food for the faithful people, and there is no sacramental union with Christ in Holy Communion that is not to be thought of as a sacrificial meal: 'For as often as you shall eat this bread, and drink the chalice, you shall show the death of the Lord, until he comes' (1 Cor. 11:26). The Eucharistic meal can only be prepared in the sacrifice of the Mass.
