The Rev Thomas Goodwin, 52, is suing Claire Fender after claiming a mix up at a petrol station saw her drive over him.
The pair had been returning to Scotland after making a trip to Manchester in September 2010.
They stopped at a petrol station in Stonehouse, Lanarkshire, to allow Mr Goodwin to swap places with Ms Fender, 41, and for her to take the wheel.
As Mr Goodwin, of Helensburgh, returned to the vehicle after buying coffee from the garage she is alleged to have unexpectedly drove off knocking him to the ground.
It is claimed she motored right over both his feet as he lay on the garage forecourt writhing in agony.
Mr Goodwin later received hospital treatment for injuries to his feet and right shoulder.
Last night it emerged he has launched a legal action at Hamilton Sheriff Court against Ms Fender, of Troon, Ayrshire, seeking substantial damages.
Lawyers for Ms Fender labelled the claim 'excessive' and insisted they have yet to see medical proof of the injuries suffered.
She has been a pastor with the Church of the Nazarene since 2010 and has conducted services across the country.
The Nazarene are an evangelical group founded in America and have churches across the world including 90 in the UK and a global membership of over two million people. Last night she said: "I will not be speaking to anyone about this but thanks for your call."
Mr Goodwin was unavailable for comment.
The case is due to call in court in June.
