Joel at Unsettled Christianity made a great post about the political implications of our Baptism and the Eucharist:

Now, I of course wouldn't
limit Baptism the Eucharist to what he states there (nor do I think he would, either). However, as he's getting at, I think too often there's been this tendency in Christianity
today to think, "God's up there in heaven doing his thing and preparing a place for me while I'm down trying to get as many people to come with me as possible."
