The message of the Apocalypse was encouragement to resist against the pressure from the cults of the Roman Gods on the Christians. By writing the Apocalypse Saint John wanted to magnify the Christian martyrs and reinforce the Christian faith. To teach this Apocalypse he choose seven churches in Western Turkey and by doing this he gave to these communities a mysterious and Significant imprint. Pergamum, Thyatira, Smyrna, Sardes, Philadelphia, Laodicea and Ephesus are the communities of the Apocalypse.The Emperor Constantine the Great declared the Christian religion over to a state religion and Constantinople was made the capitol of the Roman Empire. Therefore the Byzantine or the Eastern Roman Empire succeeded on to the Roman Empire. Many themes which are considered today as the principles of Christians religion were discussed in seven councils. These were internal discussions in the church and lasted many centuries. Four of these councils took place in Istanbul, two in Nicea, and one in Ephesus.
