Hey, Kent:

That's an interesting point... although I wonder what scriptural text the church of God bases their practice on. There are certainly many references in the bible of making music on instruments, even being as specific as mentioning particular instruments. My gospel quartet has sung in all kinds of places... including a Jewish Memorial service.
We've sung in Houses of prayer with New Orleans style trombone bands, community churches that are non denominational, and I have friends who are members of the C.O.G.I.C, who love gospel. I don't know if the COGIC church is the same as the Church of God, or even for sure, whether they use instruments in the COGIC church. I'm not questioning what you're stating... just wondering what scriptural basis the Church of God is referring to, and whether the Church of God is the same as the COGIC church.

Friendly question.

Jerry
