When did Paul write the book of Galatians?
Paul wrote the book of Galatians around 58 or 59 AD, approximately twenty years after his conversion. His conversion occurred around 37 AD on the road to Damascus. This places Galatians about eighteen years after he began his ministry around 40 AD.
Les explains that when Paul writes Galatians, it is about 20 years after his conversion. He places the writing specifically in about 58 or 59 AD. Les notes that Saul of Tarsus was probably saved on the road to Damascus around 37 AD, and after three years of desert training, it was 40 AD before he went out into the Gentile world. The Jerusalem council in Acts 15 and Galatians 2 was in AD 52, about twelve years after he began his ministry. According to Les’s time table, the first letters Paul wrote were the Thessalonian letters, written some 12–14 years after he began his ministry. So Galatians fits into a spread of 20–30 years, not all mashed together.
