"Nature, therefore, suggests that a sacrifice must precede a sacrament; death is the prelude to a communion. It was our sins that slew Christ on Calvary, and yet by the power of God risen from the dead and reigning gloriously in Heaven, He now becomes our life and has communion with us and we with [...]
"The Apostle says (1 Cor. 10:17): 'For we, being many, are one bread, one body, all that partake of one bread': from which it is clear that the Eucharist is the sacrament of the Church's unity. But a sacrament bears the likeness of the reality whereof it is the sacrament. Therefore the Eucharist is one [...]
