I'm pleased to announce that, whenever I finished summarizing all there is to summarize about The First Urban Christians, I'll be moving on to embrace...The Meaning of the Qur'an. I can't summarize the Qur'an, it seems, because no one has ever translated it. You can't. In Islamic circles, part of the Qur'an is the Arabic language. The most you can do is translate the meaning.
So there. Now you've learned something.
