The beatification for the late priest commenced on 21 March 1934 and he was later titled as Venerable in 1989. His beatification was celebrated under Pope John Paul II on 27 October 1991 in Saint Peter's Square; his liturgical feast is not affixed to the date of his death as is the norm but rather on 6 December.
