My wife's mother died and we came into possesion her Crucifix set that was used for Last Rights of her time. We discovered upon opening the cross (it normally held holy water and candles)several Eucharists.
We spoke with our priest and he said to bury them in the garden, which we did.
Good thing it feel into your hands and not someone else's. I know that set very well! My grandparents had one on the wall in their bedroom. When my grandmother passed away, her son donated it to the local church -- no hosts included. How do you suppose they got there?
