In the first three chapters of the New Testament book of Revelation the author addresses seven churches in the Roman Province of Asia (=modern western Turkey). In doing this he often makes allusions to cultural items that were especially meaningful to his first century hearers.
For example, in the name of Jesus he writes to the Church at Philadelphia:
I am coming soon … the one who overcomes I will make a pillar in the temple of my God … I will write on him the name of my God and the name of the city of my God, the new Jerusalem, which is coming down out of heaven from my God; and I will also write on him my new name. Rev 3:11–13 (NIV)
