When did 'worship service' become 'congregational meeting'?  I ask simply because I've seen a lot of references to 'congregational meetings' recently that sound remarkably like 'worship services'. 

Isn't a congregational meeting that thing where you hear the finance report, debate the colour of the new crockery or, if you are really fortunate, talk about mission and vision and stuff?  Whilst I would, and do, assert that the 'congregational meeting' is in and of itself part of the worship life of the church, it is not the same as the thing we do for an hour (or however long) every week.
