Andrea Grillo (born 1961) is a professor of Sacramental Theology and Philosophy of Religion at the Pontifical Athenaeum of St. Anselm in Rome (Sant’Anselmo) and of Liturgy in Padua at the Abbey of Santa Giustina. With the promulgation of Pope Francis’s motu proprio of July 16th, 2021, Traditionis Custodes, he has become a more important figure in Catholic thought. Many indications point to Professor Grillo as an author or at least inspirer of the document, serving as the Pontiff’s “house” liturgist and theologian, as he is often called in Rome. He joins many others from Sant’Anselmo who have exercised a disproportionate progressive influence.
The Foundations of the Motu Proprio
For years now, Professor Grillo has espoused avant la lettre the tenets of Traditionis Custodes, maintaining that the Mass of Paul VI represents the exclusive rite of the Roman Church and that the Traditional Latin Mass should be legislated in such a way that its disappearance is assured.
