Twenty UUA member congregations gave (I refuse to say paid until covenant rhetoric is swapped for service provision rhetoric) nothing to the UUA Annual Fund last year. The list is here. This post probably plays up this fact more than anything said publically by the Administration, so I won't say the congregations are being shamed. And since these churches won't have delegates seated at General Assembly, it needs to be a matter of public record.
That said, why not give at least a token amount? I'd like to know if the churches have reasons, or if the money just ran out by the time that line item came up. A few things leap to the eye. The number of small town Universalist heritage churches. Is it a protest for being underserved? The three Canadian congregations; what's the story there? Is it a protest for being eased out of the UUA against their will, or something along the lines of "no taxation without representation"? A few are federated; never a good omen for denominational loyalty, particularly if the other denomination (like the health-insurance-providing UCC) is offering better services. Some of the smallest UUA member congregations or "federated fragments" are on this list, but All Souls Unitarian Universalist Church (Colorado Springs) is "medium sized." What's the story there?
