St. Paul traveled through Thessaloniki and Berea in modern day Greece (Macedonia). The account is recorded in Acts 17:1-15. Many Protestants consider the Bereans as proto-Protestants holding to a “bible alone” theology. But they are sadly mistaken.
Here is my article “Why the Bereans Rejected Sola Scriptura” which was published in THIS ROCK Magazine a while ago.
When you read this article you will discover that the Bereans were actually Catholic in their view of Scripture, tradition and authority.
