...One day in May 1212
800 years is a long way to go back to make a point. Christians have a lot blood in their history, that's not debatable. But we all live in the present. Christianity, by and large, cleaned itself up. We're waiting for Islam to do the same.
The Reformation is what cleaned us up. We need a Muslim Martin Luther willing to stand up and nail 95 theses to the wall of the Grand Mosque and create a "protestant" version of Islam. Before the Reformation we were pretty creepy. Since 2004 in the Christian calendar is the year 1425 in the Muslim calendar, they are ripe for reform, as Martin Luther nailed his theses to the door of Wittenberg cathedral in 1517. I just hope we don't have to wait 92 more years.
