I have a Rosary that's a third-class relic of St. Jude. I got it blessed by a priest today and I swear I can feel a change in it when I touch it. Like I can feel some capacity, some power, in the Rosary now that it's been blessed that wasn't there before, but that I can't notice in my non-relic Rosaries. It's as if the Rosary's status as a relic has been "activated" by the priestly blessing. Somehow.
