With only a radio, mobile, waterproofs and toothbrush, he will be reliant on passers-by for food and water.
He aims to raise £100,000 towards a new roof so the church can continue to be a shelter for the area's homeless.
Father Hunter says "In Camden Town, a lot of people are marginalised and have no roof over their heads so I'm going to be homeless too.
"We have to do something desperate to raise this sort of money in such a short time."
Overall, the Grade-II listed church needs to raise £1m for restoration work.
However if they can reach a £100,000 target by Christmas, the Heritage Lottery Fund has promised them £350,000 towards costs.
Get up there and give em some cash if you can!!
