But the Arian heresy makes answer, and says. What says it to me? "Mark what thou hast said"? What have I said? "That the Son of a man may be compared to the Son of God." Certainly he may be compared; but not as you suppose, in strictness of expression; ¹ but for a similitude. But tell me now what you would make of this. "Do you not see," says he, "that the father who begets is greater ² in age, and the son who is begotten less? How then say ye? tell me; how then say ye, that the Father and the Son, God and Christ, are equal; when ye see that when a man begets a son, the son is less, and the father greater?" Thou wise one, in eternity thou art looking for times; where there are no times, thou art looking for differences of age! When the father is greater in age, and the son less, both are in time; the one groweth, for that the other groweth old. For by nature, the man, the father, did not beget one less, by nature, as I said, but by age. Wouldest thou know, how that by nature he did not beget one less? Wait, let him grow, and he will be equal to his father. For a little boy even by growing attains to his father's full size. Whereas you assert that the Son of God is in such wise born less, as never to grow, and by growing even to attain to His Father's size. Now then a man's son born of a man, is born in a better condition than the Son of God. How? Because the former grows, and attains to his father's size. But Christ, if it is as ye say, is in such wise born less, as that He must ever remain less, and no growth of years at least is to be looked for here. Thus then you say that there is a diversity in nature. But why say you so, but because you will not believe the Son to be of the Same Substance which the Father is? Finally, first acknowledge that He is of the Same Substance, and so call Him less. Consider the case of a man, he is a man. What is his substance? He is a man. What is he whom he begets? He is less, but he is a man. The age is unequal, the nature equal. Do you then say too, "What the Father is, That is the Son, but the Son is less"? Say so, make a step forward, say, "of the Same Substance, only less;" and you will get to His being equal. For it is not a little step you take, it is not a little approach you make to the truth, of acknowledging Him equal, if you shall acknowledge Him to be of the Same Substance, though less. "But He is not of the Same Substance," this you say. So then in that you say this, here is gold and silver; what you say is as if a man were to beget a horse. For a man is of one substance, a horse of another. If then the Son is of another substance than the Father, the Father hath begotten a monster. For when a creature, that is a woman, gives birth to anything that is not a man, it is called a monster. But that it be not a monster, he that is born is that which he is that begat him, that is, a man and a man, a horse and a horse, a dove and a dove, a sparrow and a sparrow.
