The Eucharist is a participation in the Wedding Feast of the Lamb. But then likewise a true wedding is a participation in the Sacrifice at Golgotha. The bed of marriage is properly an altar, where bride and groom offer their lives in a total sacrifice, joining and thereby engendering a new and larger organism.
When Paul says, “I beseech ye, brethren, by the mercies of God, that ye present your bodies, a living sacrifice, holy, acceptable unto God, which is your reasonable service” [Romans 12:1], he refers to the whole and perfectly general motion of the Christian toward his Savior and Lord, howsoever expressed: whether in priesthood, or martyry, or marriage – or at Mass.
The rites of the altar – the bed, the table, the throne – are the basis of society: “Wherever an altar is found, there civilization exists.” And, vice versa: where there is no altar, there is no civilization; no cult, no culture; no culture, no polis.
