Psalms 78:3

Instructed by the holy Scriptures and especially by the gospel, Pachomius endured many temptations from the demons. The holy Scriptures did not mention in detail the saints' struggle, since they used concise language in showing us the way to eternal life. Thus, for example, the law given to our ancestor Abraham was summarized in one saying, "Be well-pleasing before me and be blameless." But since we are like infants, when our parents break the bread for us, we need to be given as well the true water, as it is written. Therefore, "what we have heard and known and our ancestors have told us should not be hidden from the next generation." For, as we have been taught, we know that these words of the psalm are about the signs and portents accomplished by God for Moses and those after him. And after the model of the benefit given by them, we have also recognized in the parents of our time their children and imitators, so that to us and "to the rising generation," until the end of the world, it might be made known that "Jesus Christ is the same yesterday, today and forever."

"How great the things we have heard and known." These little verses, from "Attend, my people, to my law" up to this verse, "I will utter propositions from the beginning," are spoken from the person of Christ; the Savior himself speaks. Now the remaining verses, up to the end of the psalm, we must take as from the person of the apostles. When, then, the Lord says, "Incline your ear to the words of my mouth" — O apostles, what you have heard in secret, he says, proclaim upon the rooftops — what do the apostles say? "How great the things we have heard and known, and our fathers have told us." These things, O Lord, which you speak to us, our fathers the patriarchs and the prophets have also spoken to us. "And our fathers have told us." "They were not hidden from their children unto another generation." Therefore they spoke, so that we, their children, might know. "And he established a law in Israel. How great the things he commanded our fathers." He spoke these things carnally, but we understand them spiritually. "That they might make them known to their sons": this is, to us. Therefore he spoke to them, so that they might pass them on to us.

"How great things we have heard, and have known them, and our fathers have told them to us." The Lord was speaking higher up. For of what other person could these words be thought to be, "Hearken ye, O My people, to My law"? Why is it then that now on a sudden a man is speaking, for here we have the words of a man, "our fathers have told them to us." Without doubt God, now about to speak by a man's ministry, as the Apostle saith, "Will ye to receive proof of Him that is speaking in me, Christ?" in His own person at first willed the words to be uttered, lest a man speaking His words should be despised as a man. For it is thus with the sayings of God which make their way to us through our bodily sense. The Creator moveth the subject creature by an invisible working; not so that the substance is changed into anything corporal and temporal, when by means of corporal and temporal signs, whether belonging to the eyes or to the ears, as far as men are able to receive it, He would make His will to be known. For if an angel is able to use air, mist, cloud, fire, and any other natural substance or corporal species; and man to use face, tongue, hand, pen, letters, or any other significants, for the purpose of intimating the secret things of his own mind: in a word, if, though he is a man, he sendeth human messengers, and he saith to one, "Go, and he goeth; and to another, Come, and he cometh; and to his servant, Do this, and he doeth it;" with how much greater and more effectual power doth God, to whom as Lord all things together are subject, use both the same angel and man, in order that He may declare whatsoever pleaseth Him? ...For those things were heard in the Old Testament which are known in the New: heard when they were being prophesied, known when they were being fulfilled. Where a promise is performed, hearing is not deceived. "And our fathers," Moses and the Prophets, "have told unto us."
