Tragic Shooting in a church in Knoxville...and a question.

It appears the shooter had no connection to the Church. Neighbors are giving the standard "nice guy", "paid the rent on time", "didn't seem like the type to shoot in a church"....

One of the local TV stations filed this report this morning. http://www.wbir.com/

Multiple people have suffered gunshot wounds in what witnesses describe as a mass shooting inside a church in West Knoxville Sunday morning.
The shootings happened at the Tennessee Valley Unitarian Universalist Church on Kingston Pike.
A witness who spoke to 10 News said police had arrived and one person was being detained at the scene.
A children's production of "Annie" was taking place as part of the normal Sunday service (emphasis mine) at the time of the shooting, the witness, who is a member of the church, said. The gunman walked into a packed sanctuary and opened fire.

Please pray for these folks as they deal with this tragedy. It will be interesting to hear the coverage in the coming days to hear a possible motive.

But my question - "Annie" as a part of the normal Sunday service?
Is this where worship goes in a denomination like the Unitarians - that have no doctrine?
Is "The sun will come out tomorrow" or "Its a hard knock life" a part of their teaching?
I am sure the kids were cute and worked hard on the production - but is this Sunday Morning Worship? I don't get it.....
