Lutheranism: Too clannish, cliquish and negative?

An excellent post by Pr. McCain. In it, he asks if we are too clannish, and especially if we are too quick to point out the deficiencies of others, instead of our own treasures. Our treasures are legion, some of them are:

• A sacramental theology, which allows us to have something objective to cling to
• A church-centered economy of salvation, were we live out our faith in a community of like minded believers
  
• The cross, which gives us insight into the suffering in the world, though God is a God of love
• Undiluted, no nonsense forgiveness of sins for Christ's sake
• Salvation for babies, too
• Great music, which also teaches
  
• Pot luck!

These are just off the top of my head. I do believe Pr. McCain is correct though, we should share what God has given us, and we need not be ashamed of our heritage. Feel free to add your own.
