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.
