In the Book of the Revelation of Jesus Christ to the Apostle John, the church in Thyatira is the recipient of one of seven letters addressed to churches in Asia Minor. Each of these letters follows a similar format and begins with the Lord’s commandment to John to write to “the angel of the church” followed by an introduction to Christ as the effective author. The Lord then gives an assessment of the church which, for Thyatira, includes both praise and fervent rebuke. The lessons of this letter are critical to understanding the Christian faith and obedience to it.
