What a fearful lot! And what should especially be remembered is this: the further it goes, the more fearful it appears. First the spiritual branch is cast out. Then it withers. After that its lot becomes worse and worse.
“He is cast out as a branch.” The heavenly Vine-dresser no longer cleanses from faults the one who does not keep faithfulness to Jesus. Such a man is handed over to the will of his passions, and to the pull of his habits and sins.
The slave of passions withdraws from the church and from pious people. He turns away from divine services, from prayer, and from the mysteries. None of this is to his liking. Thus, even if for some reason the fearful voice of ecclesiastical excommunication does not thunder over him, he excludes himself from ecclesiastical communion. By his dispositions he separates himself from union with the Church, and the invisible judgment of God confirms this excommunication.
“And he withers.” A branch thrown out of the garden preserves its greenness for a short time, and only afterward becomes dead. In precisely the same way, one who has separated himself from communion with the body of Christ retains something good in himself for a time. Afterward he loses everything and becomes soulless toward faith.
Piety, eternal salvation, and Christian virtues attract neither his concern nor his gaze. The Spirit of grace departs from him. Thus Judas descended by stages of evil until he became a betrayer. For a betrayer, despair is possible, but not conversion to God (Heb 6:4-6; 2 Pet 2:20; Rom 2:5). He is a son of perdition (Jn 17:12).
“And they gather them.” Until now the judgment was particular and temporal. The Savior transfers the disciples’ gaze from one Judas to his many friends, from judgment over one man to the universal judgment.
“They gather them.” This is the same action of which He spoke in the parable of the tares: “As the tares are gathered and burned with fire, so it will be at the close of the age” (Mt 13:40). “They gather them” means that people with the same dispositions are joined into one company. Those similar in other evil passions are separated into other crowds. All this is not for joy, but for greater grief.
The friends of pride will be tormented both by seeing one another and still more by enduring the punishment corresponding to their sin. “They gather them.” In the parable of the tares it is said that the Son of Man will send His angels, and they will gather those who do iniquity (Mt 13:41).
“And they cast them into the fire.” In the parable of the tares it is also said: “and they will cast them into the furnace of fire.” We are not told what this fire is into which sinners will be cast. Certainly this is because we are unable to understand the realities of that world.
From the Lord’s clear words, only this is evident: the angels, the executors of God’s will, will subject sinners to positive punishments, and to punishments as severe as fire is fearful.
“And he burns,” more precisely, “and they burn.” If they could burn up, this would still be a happiness for condemned sinners. But the fearful calamity is that they burn, burn, and keep burning, never being consumed. Or, as the Savior says, “their worm does not die, and the fire is not quenched” (Mk 9:43).
