The final commendation is introduced in OCF 145-147. The rubrics and texts are located in the sections numbered 170 through 175. The rubrics of OCF 170 mention something you might find surprising. Here they are in full:
170. Following the prayer after communion, the priest goes to a place near the coffin. The assisting ministers carry the censer and holy water, if these are to be used.
A member or a friend of the family may speak in remembrance of the deceased before the final commendation begins.
Many bishops have attracted news coverage over the years for “banning” eulogies. As chief liturgists of their dioceses, they certainly have that power. Pastors can also make a call here, as those responsible for the orderly celebration of the rites. Ideally, you’re in a situation in which the pastor or a trusted pastoral minister works with a family to finesse how this remembrance will be handled. As long as the rubric remains in print, a eulogy is on the table as a possibility at every funeral. You or I may view that as unfortunate or ill-advised. But the Church would not take an absolute view on the matter. Comments?
