There is a rare breed among some Calvinists and that is to hold to the doctrine of Separation which is not common among Reformed, but very common among Arminian. Some examples. http://faithfpc.org/about-us/our-denomination/ Reformed in Doctrine Evangelical in Outreach Sanctified in Behavior Presbyterian in Government Protestant in Conviction Separatist in Practice http://suberroad.org Have any of you ever heard of such places? Fundamentalists will not fellowship with Reformed whom do not hold to separation yet will with those that do. Strange? I did not think that MUSIC was such a big issue and was unaware it was an essential of the faith. Is this a new breed in the Reformed movement? I have been to Reformed churches that believed everything and all the essentials, yet had contemporary praise and worship. Why deny them fellowship based solely on their music?????
