Lutheran?

I wrote the following to a friend who wonders if he is still Lutheran:

From a man who has been Methodist, Baptist, Church of God (Anderson, In), Mennonite, Pentecostal, Brethren, Non-denominational, emergent, and has dabbled in about everything else, I must say that the key is: "Where is the gospel being preached? Where is Christ?" Rare is the church that preaches grace alone through faith alone by Christ alone. And rare is the church that offers God's grace for you through the sacraments.
Every organization is messed up. We are sinners and we have to live with sinners. Pick your poison. But if you think the grass on the LCMS' lawn is withering, brother, the grass does not get much greener in any other church body, congregation, or loosely affiliated alliance.
What does it mean to be "Lutheran"? It is not a denomination. It's about the Gospel.
How bout this? Just sit down and have a chat with Benedict, change his mind about the justification thing, then we have nothing to worry about. We'll just go back home to Rome.
