I have a first-class relic of Blessed Francis Seelos.
I have also bought on ebay, 3 authentic AGNUS DEI wax disks.
The reason I bought them was, not to engage in simony, but to venerate them and to keep them from being sold for even higher and higher prices to people who are merely buying them as valuables and curiosities. I hope I didn’t do the wrong thing, I meant to obtain them to honor God.
