Question
What are the seven churches of Revelation? (the messages of Revelation 2–3)
Analysis
Seven real congregations
These were actual first-century churches on a mail route through the province of Asia (Revelation 1:11), each addressed for its own situation, from poverty and prison (Smyrna) to comfortable complacency (Laodicea). The vision behind the letters pictures Christ walking among seven golden lampstands, which are the seven churches, holding seven stars, their messengers (Revelation 1:20).
The shared shape
Most letters run: 'I know your works', then praise, then a specific fault, then a command, then a promise. Two churches, Smyrna and Philadelphia, get no rebuke; one, Laodicea, gets no praise. Christ's tone is love, not indifference: 'Those I love I rebuke and discipline' (BSB, Revelation 3:19). The famous image of Christ standing at the door and knocking is His appeal to lukewarm Laodicea (Revelation 3:20).
How the seven have been read
Beyond their plain first-century meaning, readers have taken the seven in additional ways, as representative of all kinds of churches in every age, or (in some traditions) as a prophetic sketch of successive church-history eras. The letters' own wording, real cities, real problems, real messengers, grounds them firmly as historical letters first; any wider application builds on that base.
