Ancient City of Greece
Paul's third journey
Thyateira (also Thyatira) was the name of an ancient Greek city in Asia Minor, now the modern Turkish city of Akhisar ("white castle"). The name comes from Koine Greek "Θυάτειρα" (Thuateira). It lies in the far west of Turkey, south of Istanbul and almost due east of Athens. It is about 50 miles (80 km) from the Aegean Sea.
It was an ancient Greek city called "Pelopia" (Greek language: Πελοπία), and during the Hellenistic era, in 290 BC, it was named Thyateira (Θυάτειρα) by king Seleucus I Nicator. He was at war with Lysimachus when he learned that his wife had given birth to a daughter. According to Stephanus of Byzantium, he called this city "thuateira" from Greek θυγατήρ, θυγατέρα (thugatēr, thugatera), meaning "daughter", although it is likely that it is an older, Lydian name. In classical times, Thyatira stood on the border between Lydia and Mysia. During the Roman era, (1st c. AD), it was famous for its dyeing facilities and was a center of the purple cloth trade. Among the ancient ruins of the city, inscriptions have been found relating to the guild of dyers in the city. Indeed, more guilds are known in Thyatira than any other contemporary city in the Roman province of Asia (inscriptions mention the following: wool-workers, linen-workers, makers of outer garments, dyers, leather-workers, tanners, potters, bakers, slave-dealers, and bronze-smiths).
In early Christian times, Thyateira was home to a significant Christian church, mentioned as one of the seven Churches of the Book of Revelation in the Book of Revelation. According to Revelation, a woman named Jezebel (who called herself a prophetess) taught and seduced the Christians of Thyateira to commit sexual immorality and to eat things sacrificed to idols.
The Apostle Paul and Silas might have visited Thyateira during Paul's second or third journey, although the evidence is entirely circumstantial. They visited several small unnamed towns in the general vicinity during the second journey. While in Philippi, Paul and Silas stayed with a woman named Lydia from Thyateira, who continued to help them even after they were jailed and released.
In 1922, the Patriarch of Constantinople appointed an Exarch for Western and Central Europe with the title Archbishop of Thyateira. The current Archbishop of Thyateira (since 1988) is Gregorios Theocharous. The Archbishop of Thyateira resides in London and has pastoral responsibility for the Greek Orthodox Church in the United Kingdom.
