JPX2011, here are some links and a quote I’ve collected on a few saints who saw hell. While I really don’t know that much about Fr. Barron, the copy posted on this thread regarding his thoughts on hell differ greatly from the following saints’ documentations:
St. John Bosco’s dream of hell: http://catholicism.org/bosco-dream.html
St. Faustina’s vision of hell: “I, Sister Faustina Kowalska, by the order of God, have visited the Abysses of Hell so that I might tell souls about it and testify to its existence...the devils were full of hatred for me, but they had to obey me at the command of God, What I have written is but a pale shadow of the things I saw. But I noticed one thing: That most of the souls there are those who disbelieved that there is a hell.” (Diary 741)” http://www.divinemercysunday.com/vision.htm
St. Teresa of Avila on hell: http://catholicharboroffaithandmorals.com/St.%20Teresa%20of%20Avila%20combat%20with%20Satan.html
And for a priest who would probably not agree with Fr. Barron’s encouragement regarding hope from hell for all, this from Fr. Carota: http://www.traditionalcatholicpriest.com/2014/12/20/many-people-will-saved-hell/
Excellent resources.
Also St. Therese said she saw souls falling into hell like snowflakes.
