Where do 1 and 2 Thessalonians fit in Les Feldick's study of Paul's church epistles before Ephesians?
First and second Thessalonians are placed as the last segment in the unfolding of Paul's church epistles before Ephesians. They follow the letters to the Romans, Corinthians, and Galatians in the study, and come before the prison epistles—Ephesians, Philippians, and Colossians—which begin with Acts 28 and show deeper doctrine.
Les explains that before actually starting Ephesians, he had one more segment in the unfolding of Paul's church epistles: the first and second Thessalonian letters. He reminds listeners that they came through Paul's original ministry especially in Asia Minor, Greece, and Corinth, then the letters to the Romans, the Corinthians, and the Galatians. Beginning with Acts 28, from prison, Paul writes the prison letters—Ephesians, Philippians, and Colossians—which are a jump up doctrinally in depth and understanding from what came before.
