“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 sacrament.” -St. Thomas Aquinas
