“We know the existence of the infinite without knowing its nature, because it too has extension but unlike us no limits.But we do not know either the existence or the nature of God, because he has neither extension nor limits.”

“But of that day and hour no one knows neither the angels in heaven nor the Son but only the Father.’ We are not to think that the Son of God as he is God did not know the day or hour but only that his human nature did not know it because his divine nature had not chosen to reveal it to his human nature.”

“We know that there is an infinite, and we know not its nature. As we know it to be false that numbers are finite, it is therefore true that there is a numerical infinity. But we know not of what kind; it is untrue that it is even, untrue that it is odd; for the addition of a unit does not change its nature; yet it is a number, and every number is odd or even (this certainly holds of every finite number). Thus we may quite well know that there is a God without knowing what He is.”

“You see, we find comfort in telling ourselves that the world could not exist without us, that it exists only inasmuch as we ourselves exist, inasmuch as we can represent it to ourselves. Death, infinite space, galaxies, all this is frightening, exactly because it transcends the limits of our perception.”

“Human existence is girt round with mystery: the narrow region of our experience is a small island in the midst of a boundless sea. To add to the mystery, the domain of our earthly existence is not only an island in infinite space, but also in infinite time. The past and the future are alike shrouded from us: we neither know the origin of anything which is, nor its final destination.”

“Miracles do not go against the laws of nature; we only think that because we do not know nature's laws.”
