Galatians is among the 4 greatest epistles of Paul. We know that the Letter to the Galatians played a key role in the history of the church and the contemporary church. Paul writes this letter quite contrary. For it was directed to the Christians of the Galatian church who were wandering because of the false doctrines presented by the Judaizing teachers. And we see Paul fighting against the Judaizing heresies that pervades all this Letter to the Galatians. The subject of the Epistle to the Galatians is essentially what we see in the Letter to the Romans: Salvation is justified by faith alone.
Some scholars argue that the Letter to the Galatians is the heart of the gospels, since its main point is the defense of Christian freedom, as opposed to Judaizing teachings. Galatians is the Magna Carta of Christian freedom, and together with the letter to the Romans, are letters that free us from any other attempts at theological justification that human effort is necessary for salvation. The epistle of Galatians frees us from the Mosiac Law, through a new relationship with Christ through the Holy Spirit. Along with Romans was one of the main catalysts of the Protestant Reformation. What we have to understand is that the people of Israel understood no other position unless they were under the judgment of the Law.
Do you want to be under the law or grace? What Paul calls the attention of the Galatians is not to submit to the judgment of slavery that was the Mosaic law. Our flesh has already been crucified with Christ, and now our Spirit is free to produce the fruits of eternal life. One current argues that it was shortly after the first missionary trip, and another corroborates that it was on his third trip, shortly after having written the Letter to the Romans, which bears a great resemblance to Galatians, and some still argue that Galatians was a epistle to the Romans. During his first trip Paul evangelized the southern galatia, which is formed by the Antioch of Psydia, Iconium, Lystra and Derbe.
