Rev. Buchanan
I agree with much of what you have said. I am not seeking unity without any doctrinal firmness, but at the same time, we ought to be working to seek out unity in our differences.
My pastor, Peter Wallace, who is on the OPC board for ecumenicism, has proposed (not his orignial idea mind you) that there be a General Assembly that has denom's like the ARP, CRC, PCA, OPC, RPCNA, URC, etc all in it. They can mantain their doctrinal distinctives but they will be apart of the GA. The Westminister Confession must be adhered to for joining the GA.
IMHO, this is a start to bringing catholicity back to the church...
