You've Got Mail - To The Church at Pergamum

The seven churches described in Revelation 2-3 are seven literal churches at the time that John the apostle was writing Revelation. Though they were literal churches in that time, there is also spiritual significance for churches and believers today. The first purpose of the letters was to communicate with the literal churches and meet their needs at that time. The second purpose is to reveal seven different types of individuals/churches throughout history and instruct them in God's truth.
