Though only mentioned in the Bible three times (twice in Colossians and once in Philemon), St. Epaphras was a good friend to an imprisoned Paul and great help in spreading the Gospel to the early Christian Churches of Colossae, Laodicea, and Hierapolis ... three ancient communities in Asia Minor (present-day Turkey).
You can find the three cities that St. Epaphras ministered to:
Hierapolis, Laodicea, and Colossae
