The Bible talks about us being part of the world yet not in the world. The early Christians have done more to transform the Greeco-Roman world than any culture. The modern thoughts on dignity, respect, honor and value for human life has been based on the life the early Church lived.

But you are a chosen race, a royal priesthood, a holy nation, a people for his own possession, that you may proclaim the excellencies of him who called you out of darkness into his marvelous light.1 Peter 2:9  ESV
