By St. Basil the Great
Hexaemeron (Homily 1, 3-4)
The dogmas of the end, and of the renewing of the world, are announced beforehand in these short words put at the head of the inspired history: "In the beginning God made." That which was begun in time is condemned to come to an end in time. If there has been a beginning do not doubt of the end. Of what use then are geometry — the calculations of arithmetic — the study of solids and far-famed astronomy, this laborious vanity, if those who pursue them imagine that this visible world is co-eternal with the Creator of all things, with God Himself; if they attribute to this limited world, which has a material body, the same glory as to the incomprehensible and invisible nature; if they cannot conceive that a whole, of which the parts are subject to corruption and change, must of necessity end by itself submitting to the fate of its parts? But they have become "vain in their imaginations and their foolish heart was darkened. Professing themselves to be wise, they became fools" (Rom. 1:21-22). Some have affirmed that heaven co-exists with God from all eternity; others that it is God Himself without beginning or end, and the cause of the particular arrangement of all things.
One day, doubtless, their terrible condemnation will be the greater for all this worldly wisdom, since, seeing so clearly into vain sciences, they have willfully shut their eyes to the knowledge of the truth. These men who measure the distances of the stars and describe them, both those of the North, always shining brilliantly in our view, and those of the southern pole visible to the inhabitants of the South, but unknown to us; who divide the Northern zone and the circle of the Zodiac into an infinity of parts, who observe with exactitude the course of the stars, their fixed places, their declensions, their return and the time that each takes to make its revolution; these men, I say, have discovered all except one thing: the fact that God is the Creator of the universe, and the just Judge who rewards all the actions of life according to their merit. They have not known how to raise themselves to the idea of the consummation of all things, the consequence of the doctrine of judgment, and to see that the world must change if souls pass from this life to a new life. In reality, as the nature of the present life presents an affinity to this world, so in the future life our souls will enjoy a lot conformable to their new condition. But they are so far from applying these truths, that they do but laugh when we announce to them the end of all things and the regeneration of the age. Since the beginning naturally precedes that which is derived from it, the writer, of necessity, when speaking to us of things which had their origin in time, puts at the head of his narrative these words — "In the beginning God created."
