There are now bibles online where you can click for different versions, different translations, different interepretations, historical context, etc. The same is true, or will be soon, for other faith's holy books as well.
Will there come a day when people bring their laptops (or smaller devices) to church?
They can claim that they are looking up things in their online bible.
Some will indeed be looking up bible passages.
Some will be balancing their checkbook.
Some will be reading blogs.
Some will be looking at porn.
Will the church need to deal with this?
If it does not distract others (and smaller devices won't) than perhaps not.
But the notion of looking at porn while you are in Church is troublesome.
How does this compare to the laptops-in-classroom debate that we had
Nothing I have said here is particulary to Christianity-- All
faiths will have these problems. I wonder when it will come up
and how they will deal with it.
