The most important Biblical discovery since the Dead Sea Scrolls?

Archaeologists have discovered a 2,000 year old, wirebound codex which may impact biblical studies more profoundly than any such discovery since that of the Dead Sea Scrolls.

The codex contains a map of ancient Jerusalem, bearing a cross at what is believed to have been the location of Jesus's tomb.

Some of the speculation concerning this book (including the notion that it is, or contains, the "sealed book" referred to in Revelation) seems to be  a bit overheated. But it will be fascinating to see what light, if any, it sheds on the history of the passion of Christ and on early Christian beliefs and practices.
