Way back in the 1980s, as the sex wars in the Episcopal Church really began to heat up, I heard a conservative priest tell a joke that gently mocked many of his Anglo-Catholic colleagues on the doctrinal right.

The whole point of the joke is that it is really hard to cut the ties that bind, when people have invested decades of their lives in religious institutions and traditions. And then there are the all-too human, practical details that come into play. In the end, it may be easier to edit the Apostles Creed and modernize the prayer book than it is to split the clergy pension play or divide a denomination’s trust funds.

Which brings us back to that joke that I have shared once or twice in the past. I have left the time-element in the first line intact. Like I said, it’s an old joke.

The year is 2012 … and two Anglo-Catholic priests in the back of National Cathedral are watching the Episcopal presiding bishop and her incense-bearing lover process down the aisle behind a statue of the Buddha, while the faithful sing a hymn to Mother Earth.

"You know," one traditionalist whispers, "ONE more thing and I'm out the door."

Right now, in the multi-decade United Methodist Church civil war, things may be close to reaching that point for LGBTQ clergy and their supporters on the denomination’s doctrinal left. What will it take for these believers — who are sincerely convinced that 2,000 years of Christian doctrines on marriage and sex should be changed — to decide that enough is enough?

That’s the key question that I asked during this week’s “Crossroads” podcast. (Click here to tune that in, or head over the iTunes.) What would this old “ONE more thing” joke look like today, if you turned it around — doctrinally speaking — and looked at it from the point of view of United Methodists on the left?

Maybe you would have two United Methodist pastors from the Iliff School of Theology in Denver — long a safe haven for the left — standing at the back of a global General Conference that is being held in a United Methodist stronghold in Africa. They are watching an African bishop walk down the aisle with his wife with his hands in the air singing an evangelical praise song. The service ends with the Rev. Franklin Graham giving an altar call.

One more thing and I’m out the door?

Then what? That was the other half of the equation in this podcast. Follow me through a few “ifs” here.
