I want to speak a little on practical unity.
You reap what you sow. If you sow constant conflict about ever-finer distinctions, you reap that. If you sow into the little common ground you have, you reap more common ground — some thirty, some sixty, some a hundred-fold.
I haven’t given up on doctrinal precision. I still talk theology with people, and I still seek to come to one mind with my brothers and sisters as we can — which is our Christian duty (Phil. 2:1-4). But I find that tangibly loving each other while we work together is the context within which those conversations happen productively.
“I’ll work with you if we can come to agreement on doctrine” is an approach that has not profited those who have been occupied with it. Scripture teaches us to notice that. (Hebrews 13:9)
I find it fascinating how often theological conservatives respond to my pro-untiy sentiment by tossing out a scenario like “What if a liberal lesbian Methodist minister who thinks Jesus is just a good moral teacher wants to work with you?”
It’s a good question, and it’s come up every now and again. The answer is that it depends on what we’re doing. Volunteering for the Chamber of Commerce golf tournament? No problem. Lobbying the city to get off our backs and let us feed homeless folks at the park? Sure. Introduce people to Jesus together? Of course not — we’re not talking about the same person. She’s talking about a Ghandi-type figure, and I’m talking about the Lord of the Universe in flesh.
But this isn’t an issue that crops up often, and I find it fascinating how often conservatives will use this supposed “nightmare scenario” (which isn’t that hard to deal with, actually—it’s just an awkward conversation) to avoid driving 4 blocks to establish a relationship with the historically orthodox church right down the street. They won’t take the low-hanging fruit, for fear that if we start picking, there might be a rotten apple in the upper branches. So there might, and we’ll handle that when we get to it.
But in day to day reality, there’s plenty of people who know and love the same Jesus we do — they baptize babies (or not), believe in real presence at the Lord’s Table (or not), expect a pretrib rapture (or not), celebrate Lent (or don’t celebrate Christmas, as the case may be), think too highly of Calvin, whatever. But they are our brothers and sisters, and we know it. We refuse to meet them, learn their names, start tangibly loving them…why?
