From time to time, Labour put down amendments, for example, on what happens when a church which does allow same sex marriage operates in premises on loan from another church which doesn't, or to make it easier for the Church in Wales to opt into same sex marriage, if it chooses to.
The ecclesiastical loophole was that the Church allowed modest "compensation" over and above the amount due on a loan for the hazards and delays of repayment or any legitimate reason providing it was not intrinsic to the contract.
They buy some food at discounted prices through their church, but are proud they have remained current on their mortgage, home-equity loan, insurance and property taxes.
