The Laodicean Church was only one of two Churches that did not receive any affirmation.
A city of Asia Minor situated in the Lycos valley in the province of Phrygia. It was founded by Antiochus II (261-246 BC) of Syria, who named it for his wife Laodike, and who populated it with Syrians and with Jews who were transplanted from Babylonia to the cities of Phrygia and Lydia. Laodicea was on the great highway at the junction of several important routes and was an important place after the Roman province of Asia was formed in 190 BC. It suddenly became a great and wealthy center of industry, famous especially for the fine black wool of its sheep, for the Phrygian powder for the eyes, which was manufactured there and for its banking system. In the area were the temple of Men Karou and a renowned school of medicine.
In the year 60 AD, the city was almost entirely destroyed by an earthquake, but so wealthy were its citizens that they rejected the proffered aid of Rome, and quickly rebuilt it at their own expense. It was a city of great wealth, with extensive banking operations. Little is known of the early history of Christianity there; Timothy, Mark and Epaphras seem to have been the first to introduce it. However, Laodicea was early the chief bishopric of Phrygia, and about 166 AD Sagaris, its bishop, was martyred.
