I am looking forward to unlimited opportunity to talk about one of my great enthusiasms

Rev Chris Sterry

Under the rules of the challenge, Rev Sterry can take a 15 minute break every eight hours but cannot pause for more than 10 seconds while speaking.

He is not allowed to repeat himself, must not talk nonsense, and two referees working four-hour shifts will ensure the rules are observed.

Refreshment is being provided by the local pub, and the vicar is counting on his local community to give him moral support.

'In the beginning...'

Rev Sterry said his sermon, on the Old Testament, would start at the beginning of Genesis.

He said: "This will be a proper sermon. I hope that those who come to listen to it will get something out of it.

"As a former lecturer on the Old Testament I am looking forward to unlimited opportunity to talk about one of my great enthusiasms."

Although quietly confident, he said his two greatest fears were that he might fall asleep or dry up while speaking.

"I hope that lots of people will come along to support me, especially in the middle of the night," said Rev Sterry.
