what are the seven churches mentioned in the book of revelation
In an early part of the Revelation, on the Greek island of Patmos, Jesus Christ instructs his servant John of Patmos, through an angelic intermediary, to: "Write on a scroll what you see and send it to the seven churches: to Ephesus, and to Smyrna, and to Pergamum, and to Thyatira, and to Sardis, and to Philadelphia, and to Laodicea."
