Sojourners (George Soros) has made the infiltration of churches a priority. I won't discuss why--you should be able to figure that much out for yourself along with the danger.
Currently, this is being done very carefully and quietly. It is being done in small groups and with a complete misinterpretation of scripture in service.
I recently had the displeasure of witnessing what a conquered church looks like. This was a "normal" enough looking church. The people are nice. Many are older and thus have the benefit of a proper education. But as I walked around I found the "Soul Journers" room--small groups have their own rooms.
Soul Journers -> Sojouners?!? Just a coincidence...
