Doesn't it seem like God is up to something new these days?  And if we are to keep up with Him, we may have to think about things we once held dear a little different.  Jesus' parable about the new wine and old wine skins is about people who are willing to receive what God is doing NOW. We don’t necessarily need to scrap the patterns created in the past, although we might be interested in reforming them to some degree.  There is definitely some good in old traditions.  But much more important is whether, as people of God, we treat the traditions we have come to know and love with flexibility, grace, and compassion for others so we can stay in tune with the new thing God might be doing now.
