Let me step back 1000 feet. God's idea is to focus on the things he clearly told us and emphasized in the New Testament. Most of that is not hidden in obscure Greek or church history. And we aren't doing well enough at that. Isn't that the more important problem?
I think it's man's idea to argue endlessly about whose religious practice is the right one, and we can get so lost in this that we do not have time and energy to build communities of love, serve other people, examine our own lives before God, etc. As though some religious practice or theological doctrine or some other footnote is the thing that shows that my religion or my group is the true one. Jesus tells us they will know we are Christians by our love. Love is hard. We need to really work at loving God, each other, and our neighbor. If we get that right, by God's grace, it will be a witness in a way that none of these theological disputes can ever match.
This reminds me of something Stephen Covey wrote:
Are we spending too much time and effort writing detailed policy and procedure manuals for the wrong jungle? Is this kind of foolish disputation God's idea?You can quickly grasp the important difference between the two if you envision a group of producers cutting their way through the jungle with machetes. They’re the producers, the problem solvers. They’re cutting through the undergrowth, clearing it out.
The managers are behind them, sharpening their machetes, writing policy and procedure manuals, holding muscle development programs, bringing in improved technologies and setting up working schedules and compensation programs for machete wielders.
The leader is the one who climbs the tallest tree, surveys the entire situation, and yells, “Wrong jungle!”
