Well, to begin with we have to understand new patches and old wineskins. First, it is common knowledge among the garment industry that if you sew a new piece of denim that hasn't been preshrunk onto an old, worn pair of jeans, the first time you wash them the new patch will shrink and the jeans will be a mess. Likewise, in ancient days, before wine bottles were invented, wine was stored in wineskins made of animal hide or gut. So, when we compare the parable to the stories about the Pharisees that precede and follow it we can see that what Jesus means is that new ideas aren't compatible with old practices. A case in point.
Most churches honor the long-time traditions of worship.
However, when some pastor or group of people try to update worship so that it can be understood or appreciated by younger folks, or by those outside the church, most of the time an inner war breaks out within the congregation. Recently, I've seen two commercials that speak to this. The reality is change is neither bad nor good. Change is inevitable. But sometimes it's easier to start over than it is to effect a change.
