The small city of Colossae was about 100 miles up into the mountains from the coastal city of Ephesus - a large metropolitan port city off the Aegean Sea in Phyrgia in Asia Minor. Within the mountains there was a flat area called the Lycus Valley where two rivers met that flowed into a larger river (Meander River) that winded around, flowing down from the mountains and into the Aegean Sea. Three cities dwelt in the Lycus Valley along these two rivers - Hieropolis, Laodecea and Colossea. Because Colossae was further away from the river, it declined over the years and today is nothing but a large hill today with a few ruins laying in heaps. Laodecea also declined and is no longer inhabitated. Hieropolis, however, is known for its miracle pools and a beautiful site to see, as I visited that area a few years ago.
Background of the Church in Colossae
A young man named Epaphras from Colossae was in Ephesus during the three-year ministry of the Apostle Paul (Acts 19). Upon his conversion to Christ, Epaphras traveled back home up in the mountains of the Lycus Valley to his home in Colossae to start a church of his own as an effort to share the Gospel with his friends and family. The Bible is unclear as to whether Epaphras became the pastor of that church. Either way, he was highly influential in Christianity entering into Colossae.
