The history of the next hundred and fifty years amply justifies the anxiety and severity of St. Paul. The germs of Gnostic error, which were in the air when Christianity was first preached, fructified with amazing rapidity. It would be hard to find a parallel in the history of philosophy to the speed with which Gnostic views spread in and around Christendom between A.D. 70 and 220. Eusebius tells us that, as soon as the Apostles and those who had listened "with their own ears to their inspired wisdom had passed away, then the conspiracy of godless error took its rise through the deceit of false teachers, who (now that none of the Apostles was any longer left) henceforth endeavoured with brazen face to preach their _knowledge falsely so called_ in opposition to the preaching of the truth."[14] Throughout the Christian world, and especially in intellectual centres such as Ephesus, Alexandria and Rome, there was perhaps not a single educated congregation which did not contain persons who were infected with some form of Gnosticism. Jerome's famous hyperbole respecting Arianism might be transferred to this earlier form of error, perhaps the most perilous that the Church has ever known: "The whole world groaned and was amazed to find itself _Gnostic_."
However severely we may condemn these speculations, we cannot but sympathize with the perplexities which produced them. The origin of the universe, and still more the origin of evil, still remain unsolved problems. No one in this life is ever likely to reach a complete solution of either. What is the origin of the material universe? To assume that it is not a creature, but that matter is eternal, is to make two first principles, one spiritual and one material; and this is perilously near making two Gods. But the belief that God made the world is by no means free from difficulty. What was His motive in making the world? Was His perfection increased by it? Then God was once not fully perfect. Was His perfection diminished by the act of creation? Then God is now not fully perfect; and how can we suppose that He would voluntarily surrender anything of His absolute perfection? Was God neither the better nor the worse for the creation of the universe? Then the original question returns with its full force: What induced Him to create it? We cannot suppose that creation was an act of caprice. No complete answer to this enigma is possible for us. One thing we know;--that _God is light_ and that _God is love_. And we may be sure that in exercising His creative power He was manifesting His perfect wisdom and His exhaustless affection.
But will the knowledge that _God is light_ and that _God is love_ help us to even a partial solution of that problem which has wrung the souls of countless saints and thinkers with anguish--the problem of the origin of evil? How could a God who is perfectly wise and perfectly good, make it possible for evil to arise, and allow it to continue after it had arisen? Once more the suggestion that there are two First Principles presents itself, but in a more terrible form. Before, it was the thought that there are two co-eternal Existences, God and Matter. Now, it is the suggestion that there are two co-eternal, and perhaps co-equal Powers, Good and Evil. This hypothesis, impossible for a Christian and rejected by John Stuart Mill,[15] creates more difficulties than it solves. But, if this is the wrong answer, what is the right one? Cardinal Newman, in one of the most striking passages even in his works, has told us how the problem presents itself to him. "Starting then with the being of God (which, as I have said, is as certain to me as the certainty of my own existence, though when I try to put the grounds of that certainty into logical shape, I find difficulty in doing so in mood and figure to my satisfaction), I look out of myself into the world of men, and there I see a sight which fills me with unspeakable distress. The world seems simply to give the lie to that great truth, of which my whole being is so full; and the effect upon me is, in consequence, as a matter of necessity, as confusing as if it denied that I am in existence myself. _If I looked into a mirror, and did not see my face, I should have the sort of feeling which actually comes upon me, when I look into this living busy world and see no reflection of its Creator._ This is, to me, one of the great difficulties of this absolute primary truth, to which I referred just now. Were it not for this voice, speaking so clearly in my conscience and my heart, I should be an atheist, or a pantheist, or a polytheist, when I looked into the world. I am speaking for myself only; and I am far from denying the real force of the arguments in proof of a God, drawn from the general facts of human society, but these do not warm me or enlighten me; they do not take away the winter of my desolation, or make the buds unfold and the leaves grow within me, and my moral being rejoice. The sight of the world is nothing else than the prophet's scroll full of 'lamentations, and mourning, and woe.' ... What shall be said to this heart-piercing, reason-bewildering fact? I can only answer, that either there is no Creator, or this living society of men is in a true sense discarded from His presence. Did I see a boy of good make and mind, with the tokens on him of a refined nature, cast upon the world without provision, unable to say whence he came, his birthplace or his family connexions, I should conclude that there was some mystery connected with his history, and that he was one, of whom, from one cause or other, his parents were ashamed. Thus only should I be able to account for the contrast between the promise and condition of his being. And so I argue about the world;--_if_ there be a God, _since_ there is a God, the human race is implicated in some terrible aboriginal calamity. It is out of joint with the purposes of its Creator. This is a fact, a fact as true as the fact of its existence; and thus the doctrine of what is theologically called original sin becomes to me almost as certain as that the world exists, and as the existence of God."[16]
