This is a bit of an over-simplification of a long and complicated story going back at least to the 12th century, but here goes! Because church buildings have always needed maintenance and repair no less than any other sort and repairs inevitably cost money, during the middle ages in some parts of Europe the custom became established that the parishioners paid for the maintenance and repair of the nave of the church and the parish priest - or in certain cases cases the monastic order which provided the priest - paid for repairs to the chancel - a sort of division of responsibility.
I'm speculating now, but All Saints, Marple, although it isn't mediaeval, was built in the late 16th century as a "chapelry" or local daughter church so that local people didn't have to travel into Stockport to worship. It may well be that the right to certain tithes (a sort of church tax paid in kind) and a land grant to enable the priest to either farm himself or rent out his land (the priest's "glebe") was provided for the sustenance of the priest-in-charge in exactly the same way as had long been the custom and practice for the priests in charge of the major parish churches. And the same traditional responsibiities would have been applied: the parishioners had the responsibility for the nave and the priest had to maintain the chancel.
And the fly in the ointment in cases like this is that if you buy a house built on land that was once part of the land provided to sustain the priest, you may well inherit his obligation to repair and maintain the chancel. Hopefully, lots of houses will have been built on what was originally the priest's glebe, so you won't be bearing the entire cost of any repairs on your own. But the fact is that parishes rarely go to all the hassle of chasing up this responsibility unless they've become totally desperate because they're confronted with absolutely enormous repair bills - galloping dry rot, roof collapsing, &c. So even if a lot of people share the responsibility, the contribution required can be fairly eye-watering.
So you need to hope that your solicitor's well clued up on the pre-purchase search process. And insurance is probably a good idea!
