I know I'm a latecomer to this thread, but what I found slightly concerning was the following quote:

"Churches around us here even adopted the idea to have a ballet dance ("interpretative" dance) as an "invocation". What do ye say?"

The word 'invocation' has no Biblical basis though it is well linked with the occult/spiritist practices and paganism (satanism). What/who are these churches trying to invoke?

As a former occultist, I find this trend (along with 'visions'/'contemplative prayer'/so-called 'christian yoga') quite disturbing.

However, we shouldn't be surprised, the Bible does warn us of such things.

Anyway, just an aside!
