Indeed, human free will is a dogmatic article of faith. It’s just that the Church takes choice seriously, as pro-choicers do not. It says that our choices matter and that they have consequences, including eternal ones. So-called pro-choice people want to pretend that any choice you make is as equally good as any other choice you make. In short, they insist on the dogma that choice doesn’t really matter. The Church, dwelling in reality and not in fantasy, dissent from that childish view.
