I will tell you that my Pastor/ Teaching Elder & friend, he works a secular job for a living. He does his "Representative of Christ" thing as a calling & that draws no salary. This guy (as well as other Elders) go visit their brethren churches & there they visit, teach & preach the word. Baptisms are held in a river vs a infant baptismal font & they also still wash feet (in all humility). The budget for the year is roughly 10,000 dollars....that keeps heat on in winter, AC in Summer, lighting & toilets flushing. Mostly they made & maintain the building by themselves. They also measure their growth by how much a member grows in the Word (not head count).
to me anymore, thats a very solid & biblical church then what I came from.
