Q. 1. Is it mandatory for the priest to preach a homily on Sundays and/or Holy days?
A. 1. A priest is required to preach a homily on Sundays and Holy Days in accordance with the Catholic Canon Laws that follow:
# 767 §1. "Among the forms of preaching, the homily, which is part of the liturgy itself and is reserved to a priest or deacon, is preeminent; in the homily the mysteries of faith and the norms of Christian life are to be explained from the sacred text during the course of the liturgical year."
# 767 §2. "A homily must be given at all Masses on Sundays and holy days of obligation which are celebrated with a congregation, and it cannot be omitted except for a grave cause."
# 767 §3. "It is strongly recommended that if there is a sufficient congregation, a homily is to be given even at Masses celebrated during the week, especially during the time of Advent and Lent or on the occasion of some feast day or a sorrowful event."
# 767 §4. "It is for the pastor or rector of a church to take care that these prescripts are observed conscientiously."
