Over at Fr Hunwicke's Mutual Enrichment blog, he writes the following concerning relics, which I think a nice bit that could be put to good use. Speaking of the Feast of the Holy Relics, he affirms:

This feast is, in my view, rich in themes for evangelical preaching and teaching, and ripe for wider revival. It teaches the goodness of material things against a false 'spiritualism'; it preaches the ultimately indissoluble link between Body and Soul against the sub-Christian notion that only the soul really matters; it proclaims the transforming eschatological glory which will clothe this perishable with what is imperishable, and this mortal with what is immortal, in a moment, in the twinkling of an eye, at the last trumpet.
