I am quite certain that Victoria is our Sovereign, and not her father, the late Duke of Kent, without laying any claim to the gift of infallibility; as I may do a virtuous action, without being impeccable. I may be certain that the Church is infallible, while I am myself a fallible mortal; otherwise, I cannot be certain that the Supreme Being is infallible, until I am infallible myself. It is a strange objection, then, which is sometimes urged against Catholics, that they cannot prove and assent to the Church’s infallibility, unless they first believe in their own. Certitude, as I have said, is directed to one or other definite concrete proposition. I am certain of proposition one, two, three, four, or five, one by one, each by itself. I may be certain of one of them, without being certain of the rest; that I am certain of the first makes it neither likely nor unlikely that I am certain of the second; but were I infallible, then I should be certain, not only of one of them, but of all, and of many more besides, which have never come before me as yet. Therefore we may be certain of the infallibility of the Church, while we admit that in many things we are not, and cannot be, certain at all. It is wonderful that a clear-headed man, like Chillingworth, sees this as little as the run of every-day objectors to the Catholic religion; for in his celebrated “Religion of Protestants” he writes as follows:—“You tell me they cannot be saved, unless they believe in your proposals with an infallible faith. To which end they must believe also your propounder, the Church, to be simply infallible. Now how is it possible for them to give a rational assent to the Church’s infallibility, _unless they have some infallible means to know that she is infallible_? Neither can they infallibly know the infallibility of this means, but by some other; and so on for ever, unless they can dig so deep, as to come at length to the Rock, that is, to settle all upon something evident of itself, which is not so much as pretended.(11)”
