I'm taking a class on the Old Testament and the last two weeks have been spent reading Exodus and Leviticus. I'm struck by the idea that many of the instructions revolve around being kind to one's neighbor (according to my study Bible, one of Jesus' main teachings as well) economically.
Sounds like radical hospitality to me. See, one an interpret the Bible in all kinds of different ways ;)
And yes, I should put chapter and verse references in but I have to run and bathe two small children and work for an hour before I take the kids to their Waldorf program this afternoon. So maybe I'll put them in later.
