A guy I know has started a project of getting specific priests to say Masses for specific priests, both of them living.
He’s had me say three Masses for another priest who, in turn, is offering three Masses for yours truly at the request of the same guy.
In other words, you’ll have to do the groundwork for this, going to two different parishes. Perhaps you can start by doing this with two priests you know, say, your pastor and the pastor of a neighboring parish.
This is something the Mother of all priests, Jesus’ good Mom, would appreciate very much.
Of course, when I die and I’m in purgatory until the end of the world, I would be very happy to have Masses said for me, even if I could not anymore offer Masses for those saying Mass for me.
