Relics? If you have a picture of Aunt Jessie, and you really loved her, wouldn't you keep a photo of her on your dresser or nightstand? Or, what about the bones of Elisha, who was so holy that when he died, and just his bones were left, some dead guy was thrown in, and that guy came back to life (2Kings 13:21) And it came to pass, as they were burying a man, that, behold, they spied a band of men; and they cast the man into the sepulchre of Elisha: and when the man was let down, and touched the bones of Elisha, he revived, and stood up on his feet.
And then there are the cloths that people would touch to Peter and the Apostles, and take them home, or bring them to a sick person, and the cloth would HEAL them. Or for that matter, how about Peter's shadow?
