Emergent Religion

Consider a world where Christianity had died out shortly after the canonical Bible was ratified in the 3rd century. If someone were to find the Bible in 2011 and consider it sacred scripture, what would a faith based on that book be like? Would the values, priorities and worship practices be familiar to us?  Is Christianity defined by the Bible or is the Bible defined by Christianity? Or is it both. If so then is one more dominant than the other?
