The main argument made by Hannity was, “Judge not lest ye be judged” If we were to follow this statement in the way that Hannity is using it then we would never be able to correct anyone. You wouldn’t be able to tell anyone there wrong. Jesus is not saying not to correct people, he is saying not to judge peoples souls. Father Euteneuer did not say that Hannity was going to hell. What he was doing was one of the Spiritual works of mercy, admonish the sinner.
The other argument Sean Hannity made was playing the priest sex abuse scandal card. Here is Father Euteneuer’s response...
Most surprising of all, however, was Hannity’s use of what I call the “argument from pedophilia” namely, the tendency to fall back on the Church sex abuse scandal when you’re losing an argument with a priest and have to grab for something. I have had people do this to me in front of abortion clinics, at Da Vinci Code protests and in private conversations about Catholicism for the past several years. Let’s just say I didn’t expect it from Hannity! Link
Using the priest abuse scandle as an argument against the Church is like saying Jesus' teaching is not true because of Judas. The priest abuse scandal does not stem from the teachings of the Catholic Church. It stems from sinners that are in and always will be in the Church.
