Psalms 90:2

He adds, how He became our refuge, since He began to be that, viz. a refuge, to us which He had not been before, not that He had not existed before He became our refuge: "Before the mountains were brought forth, or ever the earth and the world were made: and from age even unto age You are" [Psalm 90:2]. Thou therefore who art for ever, and before we were, and before the world was, hast become our refuge ever since we turned to You. But the expression, "before the mountains," etc., seems to me to contain a particular meaning; for mountains are the higher parts of the earth, and if God was before even the earth were formed (or, as some books have it, from the same Greek word, "framed" ), since it was by Him that it was formed, what is the need of saying that He was before the mountains, or any certain parts of it, since God was not only before the earth, but before heaven and earth, and even the whole bodily and spiritual creation? But it may certainly be that the whole rational creation is marked by this distinction; that while the loftiness of Angels is signified by the mountains, the lowliness of man is meant by the earth. And for this reason, although all the works of creation are not improperly said to be either made or formed; nevertheless, if there is any propriety in these words, the Angels are "made;" for as they are enumerated among His heavenly works, the enumeration itself is thus concluded: "He spoke the word, and they were made; He commanded, and they were created;" but the earth was "formed," that man might thence be created in the body. […]

The resurrection of the Lord is our hope, the Lord's ascension our glorification. Today, you see, we are celebrating the feast of the ascension. So if we are to celebrate the Lord's ascension in the right way, with faith, with devotion, with reverence as God-fearing people, we must ascend with him and lift up our hearts. In ascending, however, we must not get above ourselves. Yes, we should lift up our hearts, but to the Lord. As you know, not lifting up hearts to the Lord is due to pride; lifting up hearts to the Lord is called "taking refuge." After all, we say to the one who has ascended, "Lord, you have become a refuge for us."He rose again, you see, to give us hope, because what rises again is what first dies. So it [Christ's resurrection] was to save us from despair at dying and from thinking that our whole life ends with death. We were anxious, I mean, about the soul, and he by rising again gave us an assurance even about the flesh. So he ascended—who did? The one who descended. He descended in order to heal you; he ascended in order to lift you up. You will fall if you have lifted yourself up; you remain standing if you have been lifted up by him. So, lift up your hearts, but to the Lord—that is taking refuge. Lifting up your heart, but not to the Lord, that is pride. So let us say to him as he rises again, "Since you, O Lord, are my hope"; and as he ascends, "You have placed your refuge very high." How, I mean, can we possibly be proud, if we lift up our hearts to him, seeing that he humbled himself for our sakes, so that we should not remain proud?

Before the mountains were made, and the earth and the world were formed. At this place a heresy creeps in: If he was made a refuge for us before the mountains were made and the earth and the world were formed, then souls existed before the world came to be. For what does Scripture say? Lord, you have been made a refuge for us: from generation, it says, to generation: from the beginning of the world, before the beginning of the world. This is what they say. And do not think, he says, that I am the one saying it. Before the mountains were made, and the earth and the world were formed, you, he says, have been made a refuge for us. But if you were our refuge before the world was made, then souls existed before the world came to be. You divide the sentence wrongly, O heresy. Why do you slander the Holy Spirit? Speak in the way the Holy Spirit spoke. It should therefore be read thus: Lord, you have been made a refuge for us from generation to generation: and the pause is up to this point. Then another fresh beginning: Before the mountains were made, and the earth and the world were formed, from age to age you are God. You are God before the mountains were made, you are God before the earth and the world were formed, from age to age you are God, you always are, you are eternal.

Therefore, "God is our refuge and strength." To him who is able to say, "I can do all things in him," Christ, "who strengthens me," God is strength. Now, it is the privilege of many to say, "God is our refuge," and "Lord, you have been our refuge." But to say it with the same feelings as the prophet is the privilege of few. For there are few who do not admire human interests but depend wholly on God and breathe him and have all hope and trust in him. And our actions convict us whenever in our afflictions we run to everything else rather than to God. Is a child sick? You look around for an enchanter or one who puts superstitious marks on the necks of the innocent children; or finally, you go to a doctor and to medicines, having neglected him who is able to save. If a dream troubles you, you run to the interpreter of dreams. And, if you fear an enemy, you cunningly secure some man as a patron. In short, in every need you contradict yourself in word, naming God as your refuge; in act, drawing on aid from useless and vain things. God is the true aid for the righteous person. Just as a certain general, equipped with a noble heavy-armed force, is always ready to give help to an oppressed district, so God is our helper and an ally to everyone who is waging war against the wiliness of the devil, and he sends out ministering spirits for the safety of those who are in need.

From generation to generation. In this place the serpent hisses. For those who say that souls were made before the world and before they were put into bodies, say this: Lord, you have become a refuge for us from generation to generation, before the mountains were made or the world was formed — that is, before this world was created, you were our refuge — punctuating badly, understanding badly. For we ought to say it thus: Lord, you have become a refuge for us from generation to generation. And the pause of the sentence goes this far.
