When may a diocesan bishop delegate confirmation to other clergy? The introduction tells us it may be done by another bishop, by presbyters when the cause is serious, or even by presbyters when the number of those to be confirmed is large:
8. The diocesan bishop is to administer confirmation himself or to ensure that it is administered by another bishop. But if necessity requires, he may grant to one or several, determinate priests the faculty to administer this sacrament. For a serious reason, as sometimes is present because of the large number of those to be confirmed, the bishop and also a priest who, in virtue of the law or a particular concession by competent authority, has the faculty to confirm, may in individual cases associate priests with himself so that they may administer the sacrament. It is preferable that the priests who are so invited:
a. Either have a particular function or office in the diocese, being, namely, either vicars general, episcopal vicars, or district or regional vicars;
b. Or be the pastors of the places where confirmation is conferred, pastors of the places where the candidates belong, or priests who have had a special part in the catechetical preparation of the candidates.
Any clergy reading who have confirmed outside of the Easter Vigil? Any readers confirmed by a parish priest?
