minds a profession which they cannot understand. But it is not the necessary result of unity of profession, nor is it the fact, that the Church imposes dogmatic statements on the interior assent of those who cannot apprehend them. The difficulty is removed by the dogma of the Church’s infallibility, and of the consequent duty of “implicit faith” in her word. The “One Holy Catholic and Apostolic Church” is an article of the Creed, and an article, which, inclusive of her infallibility, all men, high and low, can easily master and accept with a real and operative assent. It stands in the place of all abstruse propositions in a Catholic’s mind, for to believe in her word is virtually to believe in them all. Even what he cannot understand, at least he can believe to be true; and he believes it to be true because he believes in the Church. The _rationale_ of this provision for unlearned devotion is as follows:—It stands to reason that all of us, learned and unlearned, are bound to believe the whole revealed doctrine in all its parts and in all that it implies, according as portion after portion is brought home to our consciousness as belonging to it; and it also stands to reason, that a doctrine, so deep and so various, as the revealed _depositum_ of faith, cannot be brought home to us and made our own all at once. No mind, however large, however penetrating, can directly and fully by one act understand any one truth, however simple. What can be more intelligible than that “Alexander conquered Asia,” or that “Veracity is a duty”? but what a multitude of propositions is included under either of these theses! still, if we profess either, we profess all that it includes. Thus, as regards the Catholic Creed, if we really believe that our Lord is God, we believe all that is meant by such a belief; or, else, we are not in earnest, when we profess to believe the proposition. In the act of believing it at all, we forthwith commit ourselves by anticipation to believe truths which at present we do not believe, because they have never come before us;—we limit henceforth the range of our private judgment in prospect by the conditions, whatever they are, of that dogma. Thus the Arians said that they believed in our Lord’s divinity, but when they were pressed to confess His eternity, they denied it: thereby showing in fact that they never had believed in His divinity at all. In other words, a man who really believes in our Lord’s proper divinity, believes _implicitè_ in His eternity.
