The specifics of “hell” are not ours to ponder.... regardless how it may pain some....
We are invited to ponder what Scripture reveals, as St. Thomas Aquinas did in his various ponderings on Hell. Scripture quotes Christ stating that many enter the broad road that leads to destruction, that the angels will throw the weeds into the fire, that the goats will depart to His left into eternal punishment, that Judas is the son of perdition, etc. Barron chooses to ignore this, the rest of Scripture, the Church Fathers, St. Augustine, St. Thomas Aquinas, and the entire Tradition and the Catechism (see 1033ff for example) in preference for the speculations of Karl Barth and Hans Urs von Balthasar. My reply is what St. Padre Pio said to the man who came to confession and said he didn't believe in Hell: "You will when you get there."
