The Christianity of Paul: Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ. Galatians 1:7
The region of Galatia was, in the time of the Roman Empire, a province in what is now Turkey. Paul probably visited this region during his first and second missionary journeys, and he addressed an important letter to the churches of this famously warlike people.
And in this Letter, the first words are aimed at explaining the main problem of the early Church during Paul's missionary work, the unity in the faith. But the problems in those times were multiple, not just one, hence the urgent need for the apostolic letters, including those of Paul. Although the disciples were inspired, enlightened, and guided by the Holy Spirit, the truth is that each teacher had his own little book, and that is why there were so many stories about Jesus. The confusion in the early Church was at the door. The Gospels as they are known today were written after the first century AD, while Paul's spiritual letters were written between 20 and 70 AD.
It is very likely, and this can be deduced from the expressions in most of his letters, that what most concerned Paul was the conflict with the Judaizing Christians who demanded that to enter the Church, every believer in Jesus had to first pass through the law of Moses; in other words, to enter the Church, circumcision was necessary. For the apostle Paul, this was a spiritual inconsistency with the very doctrine of the Kingdom of God, the promise of the gift of eternal life requires a change of life through the sacrament of baptism, not the fulfillment of prohibitions and commands.
This is why at the beginning of his Letter to the Galatians, the apostle Paul wisely wrote these words to warn of the dangers of heresies to the believers of the churches of Galatia: "I am astonished that you are so quickly deserting the one who called you to live in the grace of Christ and are turning to a different gospel—which is really no gospel at all. Evidently some people are throwing you into confusion and are trying to pervert the gospel of Christ" Galatians 1:6-7.
The apostle Paul emphasized his authority in most of his epistles, such as the Letter to the Galatians, and this eventually bore fruit; so much so that Christianity as it is known today is the work of Paul.
