The Christian and Missionary Alliance has churches of all stripes and it is difficult to paint them with one broad swipe of the brush. Even within the Baptist Fellowship, mentioned, of which I served for many, many years, there are a few questionable churches.
I think what is happening with this so-called Emerging church is the end results of the charismatic movement; the feel good, serve all thing which strikes some religions. The C&MA has always had a rather broad statement of faith "allowing" some charismatic direction. It was not advocated by the many, but did attract a few. Remember, the C&MA Church was the home of A.W. Tozer and one of the founders of the Youth For Christ movement.
Cheers,
