Catholics, in fact, are the only people in the world who do, can, or dare reason in matters of religion. Indeed, they are the only people who have a reasonable faith, and who believe only what they have adequate reasons for believing. They are also the only people who recognize no human authority, not even one's own, in matters of Christian faith and conscience. Sectarians and rationalists claim to be free, and to reason freely, because, as they pretend, they are bound by no human authority, and recognize no authority in faith but their own reason. Yet why should my reason be for me or any one else better authority for believing than yours? My authority is as human as yours, and if yours is not a sufficient reason for my faith, how can my own suffice, which is no better, perhaps not so good? As a fact, no man is less free than he who has for his faith no authority but his own reason; for he is, if he thinks at all, necessarily always in doubt as to what he ought or ought not to believe; and no man who is in doubt, who is unable to determine what he is or is not required to believe in order to believe the truth, is or can be mentally free. From this doubt only the Catholic is free; for he only has the authority of God, who can neither deceive nor be deceived, for his faith. It is a great mistake to suppose that the Catholic believes what the church believes and teaches on any human authority. To assume it begs the whole question. The act of faith the Catholic makes is, "O my God! I believe all the sacred truths the Holy Catholic Church believes and teaches, _because_ thou hast revealed them, who canst neither deceive nor be deceived." The church can declare to be of faith only what God has revealed, and her authority in faith is the authority not of the law-maker, but of the witness and interpreter of the law. In faith we believe the word of God, we believe God on his word; in the last analysis, that God is true, _Deus est verax_. Better authority than the word of God there is not and cannot be, and nothing is or can be more reasonable than to believe that God is true, or to believe God on his word, without a voucher.
