Galatians

The letter to the Galatians was written by Paul around 48 AD. It is the first letter he wrote, soon after returning from the areas mentioned in Acts 13 and 14. The central theme is salvation by faith alone, nothing added nor removed. He writes also in defense of his authority to combat the legalists.
