Absolutely.
In my voluntary capacity, I refer some of our service users to food banks, usually Trussell Trust ones. I can categorically state that there is no evangelising whatsoever, nor anything expected from their beneficiaries in return.
I'm atheist and would be the first to complain if there was.
Yes, many TT food banks are attached to churches, but that's because churches general have halls that are available, usually at no cost, and they want to help. Good luck finding any other community places that are happy to accommodate a food bank several times a week.
When I'm looking for food banks and there isn't a TT one near our service user, the alternatives are also often at churches. And it's because church congregations feel a commitment to help others. Whether or not you respect their faith, it's a fact that most charitable organisations have their foundation in religious groups, as ours does. We're not a religious group at all, but our founders a couple of decades ago were a bishop and a local vicar, and our original volunteers found mainly from local churches. If you look back at the origin of many well known charitable organisations you'll find the same, even though they're secular now.
Though I'm atheist, I have great respect for the Trussells in building such a massive and vital organisation. Their religion is of no importance to me, but their service is.
