Christmas always makes me think of Paul on Mars Hill. You may find that odd, but it goes back to my Dad. Dad was (and is) a preacher for a fairly traditional Church of Christ. Many of these churches frown on celebrating the birth of Christ on Dec. 25 b/c it probably wasn't the actual date (if you don't understand this "logic", just thank God and move on). Dad would always preach on the birth of Christ anyway, and when questioned about it would explain it by saying he was following the pattern of Paul on Mars Hill. Paul used a pagan idol and pagan poets and philosophers to teach the Greeks about the true God, or stated differently he used what they knew to tell them about what they didn't know. Dad would always talk about how silly it would be at a time when almost everyone turned their attention to Jesus for us to talk about something else. I thought it was brilliant then and I still do today.
Recently, I've been reading a book by Leslie Newbigin called "Foolishness to the Greeks". The title alone really got me thinking. The majority of scripture is written by people with a hebrew mindset to people with a hebrew mindset. However, the vast majority of western culture operates under a decidedly greek mindset, and there is a major difference/disconnect. Perhaps "Mars Hill" operates as a living metaphor for the Gospel in western culture. Perhaps Christians should be doing the hard work of studying and understanding culture(instead of hiding and sheltering ourselves from it, or "knocking it off" and making our own cheap imitations of it) as Paul apparantly did in order to redeem it for the sake of the Gospel. Maybe we need to recognize that all creation is saturated with God...that all truth is God's truth and therefore we can claim it wherever we find it and use it for the sake of the Gospel and the Kingdom of God.
