In my experience it’s a safe bet that most Protestants are not enthused about the veneration of relics— i.e. bits of a saint’s bone or bits of things they once used, such as pieces of their clothing (these are called “secondary relics”). That would apply even to Protestant “saints”: if I came to a Lutheran carrying a fragment of Martin Luther’s shinbone in a fancy reliquary box and asked him if he would like to venerate it, he would probably take a pass and reply, “Thanks anyway.” If I came to a Calvinist with a similar fragment of Calvin’s shinbone in a reliquary and made the same offer, he would probably knock the box from my hand with a stern Genevan rebuke.
