If so, it is because they have not the right idea of faith, nor the will to submit to the teaching authority of Christ. When Christ, the very Son of God, reveals the truth, that truth must not be accommodated to our mental variations; our own mental outlook must be adjusted to that truth. We cannot take what suits us, and reject what does not. Thus St. Paul wrote, "The knowledge of God brings into captivity every understanding unto the obedience of Christ." II Cor. X., 5. God has the right to demand the obedience of the intelligence as well as of the will; and that obedience is manifested by the acceptance of dogmatic truth revealed by Him.
Ontological and Divine Truth as identified with the Being of God is infinite and incomprehensible. But not all logical and derived truth is infinite and incomprehensible. There is a difference between truth of being and truth of thought concerning that being. The created mind can attain and comprehend truth derived from the consideration of created things. It can attain a genuine though inadequate knowledge of uncreated truth insofar as God deigns to reveal that information and insofar as human thought can express it.
He is certainly capable of comprehending that a thing is true and its opposite false, even though he cannot comprehend the full inner nature of the thing he knows to be true. For example, I know from historical evidence that Christ lived. I know that He established the Catholic Church. I know that He promised to be with that Church all days till the end of the world. I know that He wrought certain works which proved His claim to be God, and no ordinary man. All that is human knowledge on my own human level. I take His word for it that He has left Himself really present in the Eucharist. I do not fully comprehend the inner nature of His presence there. But I do understand by my human faculties the truth or falsity of facts. It is true to say that He is there; it is false to say that He is not there. I assert the truth with dogmatic certainty--a certainty based on the knowledge that the Infinite and All-perfect God must know the truth, and could not tell a lie.
Not if it be a question of merely human opinions derived by our own processes of thinking from more or less probable premises. But one who is quite conscious that he is preserved by God from error in declaring a truth revealed by God Himself is certainly justified in speaking with dogmatic certainty. And under certain conditions, well known and defined, the Catholic Church has this promised assistance of God where His revelation is concerned, so that her official dogmatic definitions are infallibly correct.
That is not universally true even where merely natural knowledge is concerned. A scientifically demonstrated natural truth is human knowledge, and it is not fallible knowledge. For example, it is infallibly true that the earth is a globe. If all human knowledge is fallible then you could not even know for certain that you had sent these questions to me and that I am answering them. Where knowledge of the supernatural is concerned I grant that absolute certainty cannot be had without an infallible teaching authority guaranteed by God.
