It's also a day when, in many dioceses around the world -- including the diocese of Rome -- the sacramental oils of catechumens, of the infirm, and holy chrism are blessed for use throughout the coming year. The blessing takes place at the Chrism Mass, which Pope Francis will lead in St. Peter's Basilica. S+L will air this mass at 9:00 am ET/6:00 am PT, repeating at 1:00 pm ET/10:00 am PT. The Mass of Lord's Supper, however, will be a simpler, private liturgy. Pope Francis, continuing a tradition from when he served as Archbishop of Buenos Aires, is celebrating this liturgy with young inmates at the Casal del Marmo detention centre. (In the above photo from 2008, then-Cardinal Jorge Mario Bergoglio washes and kisses the feet of a resident of a shelter for drug users.) To ensure the privacy of the inmates, the Vatican will not provide a live video signal for broadcasters. Instead, S+L will bring you Mass of the Lord's Supper live from St. Joseph's Oratory in Montreal, Quebec. This bilingual liturgy will be celebrated by the rectory of the Oratory, Fr. Claude Grou, CSC. The mass airs at 7:30 pm ET/4:30 pm PT, repeating at 12:00 am ET/9:00 pm PT.
