When men and women get their hands on religion one of the first things they often do is turn it into an instrument for controlling others, to put or keep them in their place. It is a long and glorious tradition.
Saul of Tarsus was doing his best to add yet another chapter to this dreary history when he was converted by Jesus to something radically and entirely different - a free life in God. Through Jesus, Paul learned that God was not an impersonal force to be used to make people behave in certain prescribed ways, but a personal Savior who set us free to live a free life. God did not coerce us from without, but set us free from within.
It was a glorious experience and Paul set off telling others, introducing and inviting everyone he met into this free life. In his early travels he founded a series of churches in the Roman province of Galatia. A few years later Paul learned that religious leaders of the old school had come into those churches, called his views and authority into question and were reintroducing the old ways, herding all these freedom-loving Christians back into the corral of religious rules and regulations.
Paul was, of course, furious. He was furious with the old guard for coming in with their strong-arm religious tactics and intimidating the Christians into giving up their free life in Jesus. But he was also furious with the Christians for caving in to the intimidation.
His letter to the Galatian churches helps them, and us, recover the original freedom. It also gives direction in the nature of God's gift of freedom - most necessary guidance, for freedom is a delicate and subtle gift, easily perverted and often squandered.
