Beroia (Βέροια) is the name of a city in Macedonia (modern Veria, Greece), mentioned in Acts 17:10 and 17:13. Paul and Silas fled there from Thessalonica after Jewish opposition arose. The city becomes famous in church history because of the noble character of its inhabitants who received the gospel.
The Bereans have become the model for all serious Bible students. Acts 17:11 describes them as "more noble than those in Thessalonica" because they "received the message with great eagerness and examined the Scriptures every day to see if what Paul said was true." This is the gold standard of Christian discernment: openness to the message combined with grounding in Scripture. The Berean approach — eager to hear, committed to verify — guards against both closed-mindedness and credulity. Every generation of believers is called to be Berean.
