Do we know the fates of any of the implausible relics Martin Luther described?

The answer to this question will depend on the relic!

**St Michael's Feather**

When I was a young altar server, the standard joke was that if you were good you would be able to find a "feather of St. Michael." We all understood this as a joke because Angels are intellectual in nature. This joke is as old as people have been able to believe in such things. 

We all know that Angels are purely spiritual beings and do not possess a physical body what so ever. The Holy Angels can appear to individuals as seen in Scriptures, but in assumed bodies.

> 1. Angels have no bodies. An intellectual nature (that is, a substantial essence equipped for understanding and willing) does not require a body. In man, because the body is substantially united with the spiritual soul, intellectual activities (understanding and willing) presuppose the body and its senses. But an intellect in itself, or as such, requires nothing bodily for its activity. The angels are pure spirits without a body, and their intellectual operations of understanding and willing depend in no way at all upon material substance.
