Congratulations on the ONA vote. When I read your post I wondered if it was a UCC congregation. I have a sibling who is a UCC ordained minister and is considering joining a movement to not marry anyone until all can marry. There is a UCC church in Minneapolis, Lyndale UCC, that will perform the religious ceremony for all couples but will not file the paperwork for any heterosexual couples until they are allowed to file the papers for same-sex couples as well (at least this was the case as of a few months ago).
Congrats again !!
