This is the perfect verse for this discussion.
In our service on Sunday morning we use cards in the pew backs for folks to use to make requests for prayer. It is nothing more than a tool.
Imagine, though, that someone began to think that the card itself was sanctified. Imagine cards with gold edging, and people with decks of cards, and little pouches on belts for holding the cards, and rules about how to lay the cards out.....
And then they begin to teach the cards, and the doctrine of cards...
I think we have to watch for signs (like a great victory in battle or a healing that was asked for on one of the cards) to prove the value of the cards before we build up too much card doctrine.
You could put a bunch of the sacred prayer cards on a chain and then chant the sacred prayer card Prayer over and over again as you work your way through the chain.
Now if we could just come up with a good chant for the sacred card chain, we could start a new sacred tradition.
How's this:
Sacred Card Chain Edged with Gold Lamination is with thee Bessed are thou among paper goods And blessed is the fruit Of thy paper tree, Aspen
