In keeping with the solemn promises that they have made in the rite of sacred ordination and renewed each year in the Mass of the Chrism, let priests celebrate “devoutly and faithfully the mysteries of Christ for the praise of God and the sanctification of the Christian people, according to the tradition of the Church, especially in the eucharistic sacrifice and in the sacrament of reconciliation.” They ought not to detract from the profound meaning of their own ministry by corrupting the liturgical celebration either through alteration or omission, or through arbitrary additions (
Redemptionis Sacramentum 31).
