The Traditional Latin Mass (also called the Roman Rite, the Tridentine Mass, the Vetus Ordo, or simply the Mass of the Ages) is the form of the Mass that grew organically from the apostolic age, took its essential Roman shape in the fourth and fifth centuries, and was codified for the Roman rite of the Latin Church by Pope St. Pius V in 1570: older local uses of more than two centuries’ standing were left free to continue. Its prayers, gestures, calendar, and silences were not invented in 1570; they were inherited. Pius V standardized what generations of saints had already prayed.

It is offered in Latin, the universal sacred language of the Western Church. The priest faces the altar, ad orientem, leading the faithful in the same direction, toward God. Most of the Canon is prayed silently. Communion is received kneeling and on the tongue. The texts shift each day with the propers, and the calendar is woven through with octaves, vigils, and saints kept for over a thousand years.

This is the Mass that converted Europe, evangelized the New World, and nourished the saints, the Mass St. Thomas Aquinas heard, that St. Thérèse loved, that Padre Pio offered. For most of the last fourteen centuries, when a Catholic in the West said “the Mass,” this is what he meant.

Be honest about the claim, though, because honesty is what earns trust: the Roman Rite is apostolic in origin and organic in growth. Its structure (readings, offering, the great prayer of thanksgiving, Communion) is there in St. Justin Martyr by the year 155; the core of its Canon is quoted by St. Ambrose around 390. It was not dictated word-for-word by the Apostles, and it was not assembled by a committee. It is a living inheritance, and you are being handed it, not tested on it.
