In a letter to the Times, Rt Revd NT Wright said he used the time being driven around to catch up on work.
He was responding to new stats, revealed at the Church of England General Synod last week, which show 11 of the Church's 42 diocesan bishops used chauffeurs. That equates to 1 in 4.
Costing the Church over £200,000, the drivers often ferry clergy to and from meetings and events within their Diocese and often to Westminster where many of them sit in the House of Lords.
In his letter, NT Wright said: "When I was Bishop of Durham, my driver and I regularly covered 30,000 to 40,000 miles a year, travelling around the 250 parishes of the diocese and to meetings in York, Leeds and often further afield.
"I used that time to work; drafting sermons, letters, lectures and even chapters of books on the laptop, or catching up with phone calls, reading, prayer or even occasionally sleep."
