Another sign of the times

Driving to the office this morning I passed by a good-sized mainline church (that shall remain nameless) with a temporary sign announcing that this coming Sunday, Oct. 16, would be "Laity Sunday" at all three services. Now I have now idea what they mean by that, and there was no explanation on the church website. But it is an interesting thought to play with. Does this mean that 51 Sunday's a year it's "Clergy Sunday"? Another great example of a sign that means nothing -- probably less -- to the thousands of drivers passing by...
