While Pentecostal and Charismatic churches have grown in number, I don't think there are nearly as many Pentecostal or Charismatic church buildings in the US as there are Presbyterian. And outside of Cleveland and certain other parts, if you want to go to a COG brand denominational church, chances are you are going to have to drive a while to get to it-- that 20 or 30 mile radius, or whatever, if it is a part of the country that has them. Could it be that some of these congregations might either have a little more say-so in who the pastor is, or a lot less say-so? Preaching is less important to most Roman Catholics than communion. The priest is believed to have power to bless the communion that no one else has. if they don't like his preaching, he is still considered to have that power. I think they can go to any of their churches but are considered a part of the local parish. Presbyterians may have a bit more input into who they have as pastor than Presbyterians.And most COG people these days wouldn't consider a member an outright sinner if he started going to a PH or A/G church instead, would they? Roman Catholics think their church is the church
