When a person faces opposition from erroneous ideology, there is a difference between refutation or winning an argument and correction. It might even be fair to say that many people are up to the task of winning an argument, but it takes a saint to be content with correction. Certainly that can be seen quite well in society these days. Most people would rather win an argument than contribute to the education of another person. This subtle difference is one that Saint Irenaeus knew quite well.
Irenaeus was a student, well trained, no doubt, with great patience in investigating, tremendously protective of apostolic teaching, but prompted more by a desire to win over his opponents than to prove them in error. Irenaeus did major work in responding to the Gnostic heresy. Gnostics claimed access to secret knowledge imparted by Jesus to only a few disciples, and their teaching was attracting and confusing many Christians. After thoroughly investigating the various Gnostic sects and their so-called “secret,” Irenaeus showed to what logical conclusions their tenets led. These he contrasted with the teaching of the apostles and the text of Holy Scripture, giving us, in five books, a system of theology of great importance to subsequent times. Moreover, his work, widely used and translated into Latin and Armenian in his day, gradually ended the influence of the Gnostics.
Saint Irenaeus was concerned with protecting the truth. But more than that, he was zealous about teaching the truth so that people would turn away from harmful errors. All of us are expected to stand up for the truth too, in our own way, among those people God has placed us. The simplest way to do that is to live the truth and to be people of integrity and mercy. Treat others as Christ, forgive as we have been forgiven, teach what we have come to know by the way we live our lives. Our witness goes a long way to teaching the truth and winning people over to the Gospel, which is way more important than simply proving others wrong and making them look foolish. Through the intercession of Saint Irenaeus, may we all gain many souls for the glory of the Kingdom of God.
