Here in the U.S., there's lots of independant evangelical churches that spring up in the oddest places. A local school district decomissioned an old country school and it was purchased by such a denomination. I was there as a volunteer and neighbor to help set it up, but that consisted of a hand carved pulpit and several used pews that had come from an older Lutheran church, which is the dominate denomination here..
First Sunday, the pastor (no priests or vicars here) came in, to the smallish congregation (about 35 or so, including yours truly), opened his well used New King James Bible to II Corinthians, 5:17 and taught an excellent 20 minute sermon on it. That's it. That was about two years ago and I visit often... teaching adult Sunday School when invited. They now have perhaps 150 members, have built a baptismal and an addition with a kitchen for social functions.
No ceremony for 'commisioning' the new church... the pastor just got right to work building the community of believers...
