The Liberal Catholic assumes as the formal motive of the act of faith, not the infallible authority of God revealing supernatural truth, but his own reason deigning to accept as true what appears rational to him according to the appreciation and measure of his own individual judgment. He subjects God’s authority to the scrutiny of his reason, and not his reason to God’s authority. He accepts Revelation, not on account of the infallible Revealer, but because of the “infallible” receiver. With him the individual judgment is the rule of faith. He believes in the independence of reason. It is true he accepts the Magisterium of the Church, yet he does not accept it as the sole authorized expounder of divine truth. He reserves, as a coefficient factor in the determination of that truth, his own private judgment. The true sense of revealed doctrine to him is not always certain, and human reason therefore has something to say in the matter, as for instance, the limits of the Church’s infallibility may be determined by human science. Within lines thus prescribed, the declarations of the Church to him are infallible, but these limits are not to be determined by the Church herself. Science will do that for her. She is of course infallible, they say, but we will determine when and in what she shall speak infallibly. Such is the absurdity which the Liberal Catholic falls into by placing the formal motive of faith in human reason.
The Liberal Catholic calls himself a Catholic because he firmly believes Catholicity to be the veritable revelation of the Son of God; he calls himself a Liberal Catholic because he believes that no one can impose upon him any belief which his individual judgment does not measure as perfectly rational. What is not rational he rejects; he is intellectually free to accept or reject. What appears good he assents to, but he is intellectually bound to no one. Thus, unwittingly, he falls an easy victim to the snare set by the devil for the intellectually proud. He has substituted the naturalistic principle of free examination for the supernatural principle of faith. As a consequence, he is really not Christian, but pagan. He has no real supernatural faith, but only a simple human conviction. In the acceptance of the principle that the individual reason is thus free to believe or not to believe, Liberal Catholics are deluded into the notion that incredulity is a virtue rather than a vice. They fail to see in it an infirmity of the understanding, a voluntary blindness of the heart, and a consequent weakness of will. On the other hand, they look upon the skeptical attitude as a legitimate condition wherein intellectual freedom is preserved, the skeptic remaining master of himself to believe or deny. They have a horror of any coercive element in matters of faith; any chastisement of error shocks their tender susceptibilities, and they detest any Catholic legislation in the direction of what they are pleased to call intolerance.
