Reading again through Saint Augustine’s “Confessions”: Day 18 (On Jesus Christ as the Immortal and Eternal Word and Truth of God)
“It is in this way, then, that you mean us to understand your Word, who is God with you, God with God, your Word uttered eternally in whom all things are uttered eternally. For your Word is not speech in which each part comes to an end when it has been spoken, giving place to the next, so that finally the whole may be uttered. In your Word all is uttered at one and the same time, yet eternally. If were not so, your Word would be subject to time and change, and therefore would be neither truly eternal nor truly immortal.
This I know, my God, and I thank you for the knowledge. I know it, O Lord my God. I confess it to you. And whoever is not ungrateful for the certainty of your truth knows it and praises you for it as I do. For we know, O Lord, that the extent to which something once was, but no longer is, is the measure of its death; and the extent to which something once was not, but now is, is the measure of its beginning. Your Word, then, in no degree either gives place to anything or takes place of anything, because it is truly immortal and eternal. Therefore it is by a Word co-eternal with yourself that you say all that you say; you say all at once and the same time, yet you say all eternally; and it is by this Word that all things are made which you say are to be made. You create them by your Word alone and in no other way. Yet the things which you create by your Word do not all come into being at one and the same time, nor are they eternal.
Why is this so, O Lord God? In some degree I see what it is, but I do not know how to put it in words except by saying that whatever begins to be, or ceases to be, does so at the moment when the eternal reason knows that it should begin to be or cease to be, although in the eternal reason there is no beginning and no ending. The eternal reason is your Word, who is also the Beginning, because he also speaks to us. So he tells us in the Gospel by word of mouth. Your Word, the Beginning, made himself audible to the bodily ears of men, so that they should believe in him and, by looking for him within themselves, should find him in the eternal Truth, where the one good Master teaches all who listen to him. It is there that I hear your voice, O Lord, telling me that only a master who really teaches us really speaks to us: if he does not teach us, even though he may be speaking, it is not to us that he speaks.
But who is our teacher except the Truth which never changes? Even when we learn from created things, which are subject to change, we are les to the Truth which does not change. And there truly learn, as we stand by and listen to him and rejoice at hearing the bridegroom’s voice, restoring ourselves to him who gave us our being. He is therefore the Beginning, the abiding Principle, for unless he remained when we wandered in error, there would be none to whom we could return and restore ourselves. But when we return from error, we return by knowing the Truth; and in order that we may know the Truth, he teaches us, because he is the Beginning and he also speaks to us.”
