Warning in the Epistle of Jude: They have taken the way of Cain; they have rushed for profit into Balaam's error. Jude 1:11
The first century after Christ, the century in which the epistle of Jude, brother of James, was written, was a time of difficulties in which Christian theology was not fully developed. The truth is that once Paul's first missionary journey ended, the first serious divisions began within the Church, leading to the first council of the Church. However, the Council of Jerusalem failed to resolve the fundamental theological issues; instead, it postponed the theological conflicts, which would later be resolved at the Council of Nicaea in the fourth century AD.
This is why the theological work of the disciples and apostles through their letters was so important to guide and strengthen the first Christians on the path of faith. And especially the apostle Paul, who was the most prolific author during this first century after Christ. But there is one among the epistolary letters of the New Testament that deserves to be mentioned, and that is the epistle of Jude, brother of James.
The Epistle of Jude is, to some extent, an example of what was happening in Christianity during its early stages. This letter is a warning against false teachers and the ungodly who threaten the correct teaching of the gospel. This is why Jude referred to this spiritual problem in his letter with a misfortune against the ungodly with the following words: "Woe to them! They have taken the way of Cain; they have rushed for profit into Balaam's error; they have been destroyed in Korah's rebellion". Jude 1:11.
For the apostle Jude, the false teachers and antichrists were not only predestined to their own destruction, as he explained in his epistle, but they also led the unwary down that same path, and that was the most serious thing. That is why the apostle recommended to the recipients of his letter to remain firm in the law of God and not fall into heresies in order to attain that life which, once obtained, cannot be lost, and with these words he wrote his request: "Keep yourselves in God's love as you wait for the mercy of our Lord Jesus Christ to bring you to eternal life" Jude 1:21.
The Epistle of Jude clearly shows that spiritual war that developed in the heart of every Christian at the beginning of the faith, because just as the blessings of Christ are valuable, also are dangerous the temptations that attack those who are initiated into the mysteries of Christ.
