It's easy to trot off the tongue that we believe in a doctrine called "the priesthood of all believers".
It's harder to explain what we mean by that, and what we don't mean.
It's harder still to articulate the cash-value: What impact does this doctrine make to the lives of Christians and churches on a daily basis?
Well, my friend of many years, Jules Beauchamp, has just put up a website to develop some of these things further. There are already some very helpful posts there coming at this from various angles, but I get the impression that there's more to come.
