So, let me put it this way, when others tell us not to participate in politics, they are expressing a fear of what kind of politic the church could be; when they say we should construct a wall of separation, they are expressing a fear of what would happen if the church took its politic seriously.
The single-most powerful political action Christians “do” is baptism and Eucharist, for in those actions we enter into an alien politics.
I would have to agree, somewhat, with McKnight. I think. Now, do you get what he is saying?
If I understand him correctly, our baptism and our participation in the Eucharist is a politic act. We are swearing off allegiance to our ‘native’ country and instead placing our citizenship in heaven. Further, in the Eucharist, we are participating (some any things in the Eucharist) in a final act of Rebellion – first against Egypt, then against the Jewish religious authorities of the day, and finally against the Roman secular authorities. These are our politics, to be sure.
Personally, I think that this is why my political change occurred. I studied the bible more closely.
