"Just as false prophets arose among the people, so too there will be false teachers among you, who will secretly introduce destructive heresies..." 2 Peter 2:1.

Heresies are teachings that contradict the core doctrines of the Holy Bible. They differ from mere theological error; they are more serious. Heresies have existed since the apostolic age, yet some have taken on a more modern form. Here are a few examples:

Prosperity Theology: claims that only those who are very wealthy and in perfect health are true Christians. It overlooks various biblical figures—such as Jeremiah, Ezekiel, Paul, and Christ Himself—who were faithful to God yet not wealthy. It also ignores the fact that true biblical prosperity involves a relationship with God and the cultivation of good attitudes. Regarding health, even the prophet Elisha fell ill and eventually died from his illness, thereby refuting the notion that a man of God does not get sick. It is worth noting that God does not favor destitution (Proverbs 10:3), but rather advocates for a realistic and balanced view of money and all other matters.

Holistic Mission Theology (Integral Mission): the problem with this theology is that it focuses solely on social issues. Social concerns are indeed present in Jesus' teachings; He preached the gospel to the poor, walked with the poor, and healed the poor. However, He prioritized the spiritual over the social. The salvation of the soul comes first; social action serves as a complement to the preaching of the gospel.

Liberal Theology: a theology that deconstructs the miracles and supernatural elements of the Bible. Everything is reduced to mere symbolism. Even the resurrection of Christ is dismissed. While the church and faith are viewed positively, proponents of this theology believe that God either does not exist or exists without intervening in the world. An examination of philosophical arguments—formulated as far back as the time of Aristotle—suggests that the existence of God is the more probable conclusion. The Bible affirms that the resurrection of Christ is literal (1 Cor. 15:14).

These heresies are more serious theological errors because they affect the salvation of the soul, which is a matter of priority in the Christian religion. Furthermore, they are modern, having emerged recently in the history of theology—specifically in the 19th and 20th centuries.
