“For them the gloom of utter darkness has been reserved.” —2 Peter 2:17 (ESV)
Dante’s Inferno sets forth nine circles of hell, with the innermost being the most hellish. Working our way in those circles are Limbo (where virtuous pagans reside), Lust, Gluttony, Greed, Wrath, Heresy, Violence, Fraud, and Treachery. Though The Divine Comedy is imaginative it is fitting that we find Socrates in Limbo and Judas near the center just shy of Satan.
While Dante’s work is fanciful, here we learn who the “gloom of utter darkness” is reserved for—false teachers. Not false teachers as in pagan philosophers, like Plato, nor those false teachers of false religions who never learned of Christ such as Gautama Buddha. They are in hell, but not the hell of hell. Peter is speaking of false teachers who have risen within the church. Inside the church, one finds the door to the darkest pit of hell. There is no safer place for the saints than the church, and, there is no more dangerous place for hypocrites than the church.
False teachers are overcome with a particular and tragic kind of slavery. Having come within inches of freedom, they reject that freedom for slavery. It is one thing to walk in the darkness, another to refuse the way of righteousness. When an Ammonite king burned his child as an offering to Molech it was a horrid evil, but it was far more evil when Manasseh did likewise, for he, knowing the way of righteousness, turned from the holy commandment of God. False teachers exchange a slavery of ignorance for a slavery that rejects the true knowledge of Jesus Christ.
It is worse to sin in the light than in the dark. It is a sin worthy of an eternal hell to sin against the light of the finite Sun, that is, the light of natural revelation as it declares the glory of God. It is a sin worthy of the hell of hell to sin against the more radiant light of the eternal Son, the light of special revelation, the light of the glorious gospel of Christ.
The way to deepest darkness is found in the light. Be warned not just of false teachers, nor only of heeding them, but of becoming one. Before any are false teachers, they are false believers. As you sit under the preaching of the gospel, that gospel will be either your great salvation or your great damnation.
