if the leaders are spiritually mature, godly men the result is blessing. If they are not mature and godly men and ignore plain teaching of the Bible (ex. biblical sexual morality), you have a disaster whether there is one or two churches. Right, Polycarp? I don't know. Depends on ones definition of "spiritually mature, godly men" I guess.
You would probably consider Calvin and other reformers to be spiritually mature, godly men. I would consider them to be ungodly men (at best.)
How spiritually mature and godly are the leaders of the RC church in your area? What impact has it had on the church?
