The evening Mass on Holy Thursday, April 18 commemorated the institution of the Eucharist and modeled Christian service in the rite of the washing of feet, received by 12 seminarians of St. Charles Borromeo Seminary. Archbishop Charles Chaput washed the feet of two seminarians while Fathers Christopher Cooke and Christopher Moriconi — who also preached the homily for the Mass — washed the feet of the others during the solemn liturgy at the Cathedral Basilica of SS. Peter and Paul, Philadelphia. (Photos by Sarah Webb)
