Celebrate the Difference?

Monday is Reformation Day, yes I know it's also Halloween.
Interesting that for most people the second is familiar and the former a ?
Reformation Day remembers the protestant Reformation's beginning. A renewal movement that's given us more types of churches than some realize and few can justify. I have to do a lot of reading each year on the topic and as I get older I just wonder and get depressed. What's the argument about? Am I still protesting and should I be? And it seems no matter how much we try, the same old tendency to argue keeps reappearing. I spotted this little slogan and thought it expressed my feelings pretty well.
Just for the record, I want to celebrate our differences. And I really do want to hear what others have to say.
