That is interesting, Father. I can only speak to what is my own pastoral practice and, beyond that, the practices I have encountered, had related to me, or otherwise experienced. I am thus unfamiliar with placing a parish’s funeral register upon the altar for remembrance of those inscribed in it.
I, speaking personally, would not be comfortable removing the funeral registers from their safekeeping under lock and key in order to place them on the altar for the duration of the Masses of the month of the Holy Souls because of the danger, however remote, that something could happen to the registers.
Those who have the cura animarum would, I trust, have the habitual intention to pray for the souls of their own parishioners who have been called from this life and would have, therefore, a particular intention for them in the Masses offered during the month of November alongside and together with those whose names have been submitted for remembrance…whatever the fashion by which those names are consigned and memorialized. That at least is how I was formed.
