I am convinced that CCM so called is not of God, but of the world. There was a time when as a young convert I used to buy tapes and listen to what may be labeled as CCM. It was not English, but CCM nevertheless. I thought it was "the thing to do", listening to such music, that is. But after some time I began to be more and more disturbed in my spirit as respected that music, and so I eventually ceased listening to it. It had sort of become an addiction to me also. I never regretted putting it away.
As for CCM and churches I believe true churches of Christ will not tolerate CCM in their services. I come to think about how in England William Huntington and certain others were opposed to the increasing emphasis on music in the services, especially instrumental music. He said it was of the devil, and others with him. If I recall aright his congregation did sing hymns and psalms in the services, but they were opposed to the new thing of bringing in manifold instruments into the meeting house. If such an approach was good enough for Huntington, who was an Independent, and for the old Particular Baptists, then it should be good enough for today's Baptists, if they be of Christ, that is.
About the most beautiful congregational singing I have ever heard was by some Primitive Baptist church in USA. It was non-instrumental, male and female voices mixed in powerful hymn-singing. And the lyrics were Biblical and God-exalting. I happened to come across it on the internet. Such beautiful singing I have never encountered in my country, where all sects and denominations professing Christ have instruments in their services, some more some less.
I think that if some old Baptists like Gill, Kiffin, Knollys etc. were given to visit the earth today they would be shocked at the worldly music posing as "Christian music" amidst the churches who profess to be of Christ.
