One of the things that struck me in my recent visits to church is the oddness of the our pulpit. The bishop controls the height with a switch near his seat (at least in large American churches). I think this would be very strange to a visiting non-member.
I like how the pulpit in our church is not reserved for just the bishop, but is in fact open to anyone (once a month at least) in the congregation. The fact that it is adjustable means that we are not just accepting this, but actively encouraging full participation. This is one of the many democratic features of our church that I like (and I'm not just saying this to stave off Nate's criticism of whining in the bloggernacle).
However (you knew this was coming), I don't really think that primary children should be encouraged to bear their testimonies during fast & testimony meeting. Sure, it's cute, and they seem to enjoy it, but what's the point? Do they really have testimonies? Is repeating what your parent whispers in your ear faith-promoting? I find it a bit creepy.
But that's the price you pay when you live in an open society (so to speak). I guess all having free access to the pulpit is worth a few kids drooling on the mike.
