What does O'Neill say about God and religion?

For Tyrone, a troubling problem is his sons' rejection of their Catholic faith, a foundation stone in their "shanty Irish" heritage. His complaints about their rejection of religion occasions Jamie's scoffing observation that Tyrone himself is a truant Catholic, which Tyrone must admit. He insists, though, that he still believes in God, which his sons do not. He is particularly upset with Edmund's godless and pessimistic view of life, claiming that it has been learned from reading depressing, atheistic poetry and philosophy.
