Having read Peter Westmore's article "Check out religion apps for smartphones!" and his promise to write another article on the wretched things, I ask respectfully. Please don't!
My vision of Mass, church, brothers and sisters sharing Eucharist with me, is not a vision of looking around and seeing hundreds of people gazing at their phones (even if discreetly) instead of being deep in contemplation and participation of the mysteries taking place.
If we begin gradually to use smartphones for Mass responses what's next?
Remember the slippery slope always begins with some small change for what seems to be a good reason.
