And the winners are...

Sr. Mary for the most creative guess (at least from a 14 year old's point of view)
Tim Ferguson for the snarkiest guess (you'd fit in nicely with my family)
Mark and Tim for guessing the closest (yes, unfortunately it is one of the Stations of the Cross)
Fr. Dennis - thank God it is NOT a prayer labyrinth! (those things are creepy)

Good guesses all around, but unfortunately none were correct. The answer is....The 13th Station - Jesus is taken down from the cross. Don't feel bad though, even the people at our church can't identify them...Really, they hand out guide books each Friday when we pray the Stations.
Don't you just love abstract church "art"?
