Liturgically dance like nobody's watching.
Pray like nobody's got the dinner on at home.
Write letters to the newspaper about traditional language in the liturgy like nobody cares.
Advertise "Back to Church Sunday" like most people these days have just drifted away.
Confuse the Persons of the Trinity like Athanasius isn't looking down on you from heaven right now.
Preach like nobody's listening.*
Hold Church Meetings like everybody's going to live forever.
Arrange flowers like that one at the back isn't really a triffid.
Rip out pews like the Chancellor of Gloucester Diocese doesn't know how to produce very large Acrobat documents.
Pontificate on sexual morality like nobody's paying any attention.
* They're not. Don't worry.
