Tests that we would rather explain away, a Reflection on Mark 10:17-31

Three years ago, three long-divided denominations, Methodists, Catholics, and Lutherans, made a public commitment to unity. Their agreement "on justification by faith, or how individuals are forgiven and brought into a right relationship with God, began with a colorful opening procession in which robed leaders of the three historic Christian traditions walked side by side."

I'm going to have to say that this doctrine is important and has been divisive. But, I wonder what joint statement they could issue on their understanding of selling all (17-22). Or, what joint statement could the possibly issue about Christianity requiring someone to desert work, home and family (29-31)?

Yes, I know that Mark's community thought the end of the world was near and that they wouldn't have to live long without assets. But, still. What is the source of our happiness? How closely are we willing to live to Jesus' test of who would get eternal life?
