Galatia was a region, not a city. Paul knew the congregations there well. Galatians is one of the earliest epistles, or letters. It shows something, then, that already in this, one of the earliest epistles, Paul begins with a furious defense of the Gospel. This is how quickly things can go wrong, how prone we are to turn back to the Law for what it can’t give, not because it isn’t good and salutary, but because we aren’t.
