if you wish to create an entry about "non-institutional" Churches of Christ and the philosophies of their beliefs/differences with mainstream Churches of Christ, by all means do so. Idiosyncratic dogmas of a small pocket of people do not belong in an article about the whole religious fellowship. The reality is that non-institutional Churches of Christ should have a seperate entry where the material you wish to include should be placed, as this movement has in reality formed a different body/philosopy.
