God's Existence Known By Reason
1. Please give me evidence that God exists. I have never had any such evidence for I do not accept the Bible.
What do you mean by evidence? Some people think that evidence must be seen and touched, as an animal sees a patch of grass and eats it. But men are not mere animals. They have reason, and can appreciate intellectual evidence. For example, the evidence of beauty in music or in painting is perceived by man's mind, not by his senses. An animal could hear the same sounds, or see the same colors, without being impressed by their harmony and proportion. Apart from the Bible altogether, reason can detect sufficient evidence to guarantee the existence of God.
2. What is this evidence for God's existence, apart from the Bible?
There are many indications, the chief of which I shall give you very briefly: The first is from causality. The universe, limited in all its details, could not be its own cause. It could no more come together with all its regulating laws than the San Francisco Harbor Bridge could just happen, or a clock could assemble itself and keep perfect time without a clock-maker. On the same principle, if there were no God, there would be no you to dispute His existence. A second indication is drawn from the universal reasoning, or if you wish, intuition of men. The universal judgment of mankind can no more be wrong on this vital point than the intuition of an infant that food must be conveyed to the mouth. The stamp of God's handiwork is so clearly impressed upon creation, and, above all, upon man, that all nations instinctively believe that there is a God. The truth is in possession. Men do not have to persuade themselves that there is a God. They have to try to persuade themselves that there is no God. And no one yet, who has attained to such a temporary persuasion, has been able to find a valid reason for it. Men do not grow into the idea of a God; they endeavor to grow out of it.
The sense of moral obligation confirms these reasons. In every man there is a sense of right and wrong. A man knows interiorly when he is doing wrong. Something rebukes his conduct. He knows that he is going against an inward voice. It is the voice of conscience, dictating to us a law we did not make, and which no man could have made, for this voice protests whether other men know our conduct or not. This voice is often quite against what we wish to do, warning us beforehand, condemning us after its violation. The law dictated by this voice of conscience supposes a lawgiver who has written his law in our hearts. And as God alone could do this, it is certain that He exists.
Finally, justice demands that there be a God. The very sense of justice among men, resulting in law-courts, supposes a just God. We did not give ourselves our sense of justice. It comes from whoever made us, and no one can give what he does not possess himself. Yet justice cannot always be done by men in this world. Here the good often suffer, and the wicked prosper. And, even though human justice does not always succeed in balancing the scales, they will be balanced some day by a just God, who most certainly must exist.
3. You, as a Priest, argue to a clock-maker. I, as a rationalist, ask, "Who created your uncreated clock-maker?"
That is not a rational question. I say that the universe is obviously created, and that what is created supposes a Creator who is uncreated, or the problem goes on forever, the whole endless chain of dependent beings as unable to explain itself as each of its links. It is rational to argue to an uncreated clock-maker. It is not rational to ask, "Who created this uncreated clock-maker?" God was not created. If He were, He would be a creature and would have a creator. His creator would then be God, and not He Himself. God always existed. He never began, and will never cease to be. He is eternal.
4. You talk of universal persuasion. Men used to believe that the world was flat!
A sufficient reason for that error is evident, viz., lack of data, and the fact that men followed their senses, which seemed to say that the earth was flat. That was not a judgment of the pure reason. The senses supplied no immediate manifestations that there might be a God as they indicated that the world might be flat. The cases are not parallel, and the transition from a judgment based upon the senses to one based upon pure reason is not valid. In any case, the scientific and metaphysical proofs justify belief in God quite independently of this psychological reason. They would be valid supposing that only one man in a million believed in God's existence. This latter supposition, however, will never be verified, for the common rational judgment of the vast majority will always intuitively perceive this truth.
5. There is no need to talk of future balancing of the scales. Virtue is its own reward in this life, even as the wicked endure remorse.
That will not do. Consciousness of virtue is not much good to a man about to be wrongfully hanged and who cannot live to enjoy it. Nor does vice always bring proportionate remorse. Many are too hardened to experience deep remorse. There will be a levelling-up some day, after this life, and by God.
6. Joseph McCabe believed in God, but he renounced bigotry and became an Agnostic.
There are many men such as Joseph McCabe who have given up their profession of a belief in God. But, they do not give up that belief because Agnosticism offers them a higher and holier life. They find Agnosticism less irksome, whether it be by emancipation from moral laws, or from the restraints of truth and logic. Nor should you talk of bigotry. Many Agnostics have a far worse bias than that which they attribute to believers, garbling facts and distorting evidence without any of the scruples which one who really believes in God would certainly experience.
7. If I sincerely believe that there is no God, and there be a God, would not invincible ignorance save me?
Such ignorance is not invincible. You can overcome it. You violated your reason in suppressing its spontaneous concept of God, and by persuading yourself that religion is false. If you took the pressure off your reason and let it swing back to the Supreme Cause of its very being, it would do so as the needle to the pole. Pascal rightly says that there are two types of men, those who are afraid to lose God, and those who are afraid that they might find Him.
