You know how it is with most religious denominations. They want to affirm lay ministry. They want to have lay ministers. But they don't want to confuse them with real ministers - you know, minister ministers. They have to minister in a lay kind of way - that's how you tell the difference. And ministry can be very wide - including all sorts of church offices you never dreamed of - no, not those offices. Not the small, dusty rooms containing a banda machine and the church secretary. So here's a quick guide to those laity who exercise ministry. But not in a minister kind of a way. More of a lay way.
Church Steward (Methodist) - Person in smart clothes who runs things.
Door Steward (Methodist) - Person in smart clothes whose job, even for one day, is better than the life of a sinner, who has to stay away.
Circuit Steward (Methodist) - Person in smart clothes responsible for the electrical safety of the church.
Treasurer (All denominations) - Person who resigns in a huff a lot. Especially once they discover that huffs can have the tax reclaimed on them.
Organist - Ruler of all (s)he surveys. Increasingly replaced by CD players, MP3 players or, in very modern Anglican churches, barrel organs. Another person who resigns a lot, normally in a dudgeon. A dudgeon is like an underground huff.
Pastoral Assistant (Church of England)- Person who takes minutes.
Elder - Smelly green wooden object. Sorry, that's the elder tree, isn't it?
Local Preacher (Methodist) - Theological Lone Ranger.
Worship Leader (All) - Somebody who requires no training. Or, sometimes, musical ability.
("Lay") Reader (Church of England) - Person suffering from extreme frustration, who gets to preach on the Sundays after Christmas and Easter when the vicar has a holiday. Constantly hoping for a (minor) accident to the vicar so they can step into the breech and preach.
Church Warden (Church of England) - Constantly fearful of a (minor) accident to the vicar, in case they have to step into the breech and preach. Responsible for the fabric of the church. No, not voile and lace. The "other" fabric.
Executive Assistant Archdruid: - Person who will never get the top job. Ever.
Deacon - In some nonconformist bodies, person awaiting the call from God to wield the (metaphorical) knife on the minister. God's Will will always call time on the minister in the end...
Sidesman/woman/person (Church of England) - No, not a clue.
Cleaners, welcomers, people who volunteer to paint, tea makers - Christ in disguise.
