I am often encountered with the claim that the Christian God is terrible because He (will) send many humans to Hell. “How could He design a universe where only (good) Catholics go Heaven? What about the rest (majority of the population) which happened not to be born catholic?” Etc.
I find hard to find an answer to this which “satisfies me”. Can you point me out to some key arguments, and if possible, to some books or theologians or Doctor of the Church or the like, where I can read about this?
Thanks. God bless.
