If it was true that the universe was a chance happening, and a necessary sequel of divine nature, whence come the imperfections and faults which we remark? For example, corruption which fills the air with bad odor, many disagreeable objects, so many disorders, so much evil, so many crimes and other like occurrences. Nothing is more easy than to refute these objections, for one cannot judge of the perfection of ancient existence only by knowing its essence and nature, and we deceive ourselves in thinking that a thing is more or less perfect, as it pleases or displeases, is useful or useless to human nature; and to close the mouths of those who ask why God has not created all men without exception that they might be guided by the light of reason, it is enough to say that it was because the material was not sufficient to give each being the degree of perfection that was most suitable for him, or to speak more proper, because the laws of nature were so ample and extensive that they could suffice for the production of all things of which an infinite understanding is capable. CHAPTER III. What God Is. I. Until now we have fought the popular idea concerning the Divinity, but we have not yet said what God is, and if we were asked, we should say that the word represents to us an Infinite Being, of whom one of his attributes is to be a substance of extent and consequently eternal and infinite. The extent or the quantity not being finite or divisible, it may be imagined that the matter was everywhere the same, our understanding not distinguishing parts. For example, water, as much as water is imagined, is divisible, and its parts separable from one another, though as much as a corporeal substance it is neither separable nor divisible. [22] Thus neither matter or quantity have anything unworthy of God, for if all is God, and all comes surely from his essence, it follows quite absolutely that He is all that he contains, since it is incomprehensible that Beings quite material should be contained in a Being who is not. That we may not think that this is a new opinion, Tertullian, one of the foremost men among the Christians, has pronounced against Apelles, that, "that which is not matter is nothing," and against Praxias, that "all substance is matter," without having this doctrine condemned in the four first Councils of the Christian Church, oecumenical and general.
