My first read this year is Spencer Burke's A Heretic's Guide to Eternity. I agree with some (maybe most) of where he's going so far, but more than anything, I appreciate that Spencer is willing to push the envelope in order to get the discussion going (he seems to be the type to say something controversial in order to then step back and watch the chaos ensue).
He writes about Matthew 13:24-30,
Determining who is in and who is out is the primary way that the church as institution tries to control grace.
Jesus told a story about this in the gospel of Matthew. It concerned a wheat farmer who had spent a hard day planting. While he was sleeping, his enemy crept onto his land and sowed weeds among the wheat. When the wheat began to sprout, the laborers noticed the weeds growing, so they went to the landowner and asked him if they should pull up the weeds. "No," he answered, because while you are pulling up the weeds, you may root up the wheat with them. Let both grow together until the harvest. At that time I will tell the harvesters: First collect the weeds and time them in bundles to be burned; then gather the wheat and bring it into my barn.'"
This story reflects the tendency humans have to want to do God's business. Institutional religion usually aspires to do the landowner's job- God's job. They want to determine who is wheat and who is weed.
Churches assume their role is about eternity when in fact eternity is God's business. The landowner in Jesus' story is very clear that his workers cannot separate the wheat from the weeds, for they might pull up perfectly good wheat in their zeal to remove the wayward weeks. When explaining this story to his followers, Jesus makes it clear that the task of determining who is in our out is not the responsibility of humans, no matter how qualified they believe they are. I would likewise argue that the church should not be so focused on eternity. The church's task is to help people follow Jesus here on earth.
Seems to play into a pretty solid Kingdom of God theology. Thoughts?
