An average Amish church has one bishop, two ministers, and a deacon.
When a new church starts, or a district becomes large enough that it is time to have it divided it means it is also time to ordain new ministers.
Ordinations occur on the day of communion, which makes a long day even longer. Communion is usually over around 4 PM and then it's time for the ordination proceedings to begin. Visiting bishops, ministers, deacons, and of course any of the home districts ministry go to a room away from where services had been held and one by one the members will take turns going to the door of that room and whispering the name of the man they think would make a good minister.
After the votes have been counted the ministry will file back into the room carrying a stack of songbooks each held shut with a rubber band and place them on a little table at the front of the room. They will then call the names of all the men that had received three or more votes. They come forward and take a book and sit on a bench that has been cleared for them.
The bishop will open the books one by one looking for a little piece of paper they had tucked into one of the song books. When the paper is found it indicates that God has chosen that man to be a minister. Lots of crying follows, as the bishop places his hands on the new ministers head and ordains him to now be a messenger of God.
In order to ordain a new bishop all ministers in that district have to have been a minister for two years. Until that happens a bishop from another district will care for that church too. Bishops are chosen much the same way, but instead of voting for any man only ministers are eligible to become a bishop.
Being ordained is often not the choice of the person being ordained, and it is a lifetime commitment. Now on top of all their usual responsibilities they also need to lead a church, unpaid.
