Psalms 103:1

In like manner, "these fatty parts of the ram that are around the kidneys and these that cover the interior parts" are commanded to be placed on the altar. So you who hear these things should know you ought to offer on the fire of the altar everything that is more sinful within you and hides your "inner being" so that all your "inner being" may be cleansed and you also may say, as David said, "Bless the Lord, my soul, and all that is within me, bless his holy name." For unless that sinfulness that touches your "inner being" should be removed, your inner being cannot lay hold of the subtle and spiritual sense and cannot receive the understanding of wisdom; therefore, it cannot praise the Lord.

However, rightly so, a man has not many, but two feet; for four feet belong to wild animals and beasts, and two to birds. Therefore, a man is like a bird, who seeks lofty things with his sight and flies with a certain stroke of the senses' keenness. And therefore it is said about him: Your youth will be renewed like the eagle's; because he is closer to heavenly things and higher than eagles, who can say: But our conversation is in heaven.

And that the writer was speaking of baptism is evident from the very words in which it is stated that it is impossible to renew to repentance those who were fallen, inasmuch as we are renewed by means of the laver of baptism, whereby we are born again, as Paul says: “For we are buried with him through baptism into death, that, as Christ rose from the dead through the glory of the Father, so we, too, should walk in newness of life.” And in another place: “Be renewed in the spirit of your mind, and put on the new person that is created after God.” And elsewhere again: “Your youth shall be renewed like the eagle,” because the phoenix after death is born again from its ashes, as we being dead in sin are through the sacrament of baptism born again to God and created anew. So, then, here as elsewhere, he teaches one baptism. “One faith,” he says, “one baptism.”

But let us speak of death as common to all people. Why should we be afraid of it, when it generally does not harm the soul? For it is written, “Do not be afraid of those who kill the body but cannot kill the soul.” Now through death the soul is freed, while it separates itself from the dwelling place of the body and divests itself of the wrappings of disquiet. And so let us too, while we are in the body, following the way of death, raise up our bodies from this fleshly couch and arise from the tomb, as it were. Let us withdraw from the bond of the body and leave all things whatsoever that are of earth, so that when the adversary comes he may find nothing of his in us. Let us strive for the eternal and fly up to the divine on the wings of love and the oars of charity. Let us rise up from here, that is, from the things of the age and those of the world. For the Lord has said, “Arise, let us go from here,” teaching that each one should arise from the earth, raise up his soul that lies on the ground, lift it to the things that are above and call forth his eagle, the eagle of whom it is said, “Your youth will be renewed like the eagle’s.”

[Daniel 10:16] "O my lord, at the sight of thee my joints are loosed..." Theodotion interprets it this way, in accordance with what we read in the One Hundred and Second Psalm: "Bless the Lord, O my soul, and all that is within me, bless His holy name." (Psalm 103:1) For our inward nature must direct its gaze without, before we deserve to behold a vision of God; and when we actually have beheld a vision of God, then our inward nature is converted within us and we become wholly of the number of those concerning whom it is written in another Psalm: "All the glory of the daughter of kings is within, in golden borders" (Psalm 45:13).

..."Bless the Lord, O my soul! And all that is within me, His holy Name" [Psalm 103:1]. I suppose that he speaks not of what is within the body; I do not suppose him to mean this, that our lungs and liver, and so forth, are to burst forth into the voice of blessing of the Lord. There are lungs in our breast indeed, like a kind of bellows, which send forth successive breathings, which breathing forth of the air inhaled is pressed out into voice and sound, when the words are articulated; nor can any utterance sound forth from our mouth, but what the pressed lungs have given vent to; but this is not the meaning here; all this relates to the ears of men. God has ears: the heart also has a voice. A man speaks to the things within him, that they may bless God, and says unto them, "all that is within me bless His holy Name!" Do you ask the meaning of what is within you? Your soul itself. In saying then, "all that is within me, bless His holy Name," it only repeats the above, "Bless the Lord, O my soul:" for the word "Bless," is understood. Cry out with your voice, if there be a man to hear; hush your voice, when there is no man to hear you; there is never wanting one to hear all that is within you. Blessing therefore has already been uttered from our mouth, when we were chanting these very words. We sung as much as sufficed for the time, and were then silent: ought our hearts within us to be silent to the blessing of the Lord? Let the sound of our voices bless Him at intervals, alternately, let the voice of our hearts be perpetual. When you come to church to recite a hymn, your voice sounds forth the praises of God: you have sung as far as you could; you have left the church; let your soul sound the praises of God. You are engaged in your daily work: let your soul praise God. You are taking food; see what the Apostle says: "Whether you eat or drink, do all to the glory of God." [1 Corinthians 10:31] I venture to say; when you sleep, let your soul praise the Lord. Let not thoughts of crime arouse you, let not the contrivances of thieving arouse you, let not arranged plans of corrupt dealing arouse you. Your innocence even when you are sleeping is the voice of your soul.

Brothers, let your holiness keep in mind that I recently preached this, namely that a person should be remolded into a younger age through righteousness, and though wearied by the weakness of old age he should be born again into childhood by the character of innocence in such a way that we may see old people become infants again by the mystery that intervenes, for there is a certain renewal in ceasing to be what you were and to take up what you had previously been. I say, there is renewal, which is also why neophytes receive their name, because in some newness they cast off the spots of oldness and have received the grace of innocence, as the apostle says, “Put off the old person with his deeds and put on the new person, who was created in the image of God.” Thus also holy David says, “Your youth will be renewed like that of an eagle.” He understands that the perishable things of our life can be revived through the grace of baptism and that that which had fallen by the oldness of sins can be renewed by a certain youthfulness. But that you may understand that the prophet is speaking about the grace of baptism, he compared the renewal itself to an eagle, a bird which is said to lead a long life by constantly changing its appearance and to grow young with a new set of wings when the old feathers are dying off, in such a way that it clothes itself with a revived newness of clothing as it puts off its old plumage. Thus we understand that it is not the limbs but rather the feathers of the eagle that feel old age. Therefore, it clothes itself anew, and as feathers sprout up anew, the old mother is turned back into a chick. Then she must be compared to chicks, since she with shining feathers must plan inexperienced flights and restrain her once experienced beatings of her wings as if she were a newborn, idle bird in the nest. For although she knows how to fly from her past practice, she nonetheless has little confidence because of the thinness of her feathers. Therefore, the holy psalmist prophesied this concerning the grace of baptism. Our neophytes, recently baptized, have (like eagles) put off the old skin and taken on the new clothing of holiness and are adorned with the revived grace of immortality as with light feathers, while their old blemishes die off, so that in them the dead sins of old age grow old, but life des not grow old, for like an eagle turned back into a chick, they have been called back to infancy. They know about how to live in this age, but they have the carefree state that comes from the healing of righteousness.

Who does not see how impious and how sacrilegious it is if a person, who has been converted to good things through penance for his past evils, believes that there can be no forgiveness for any sin? What else is being done with these words than that the hand of the all-powerful physician is being pushed away by the vice of despair, from effecting human salvation? For the physician himself says, “Those who are healthy do not need a physician, but the sick do.” If our physician is an expert, he can cure all maladies. If God is merciful, he can forgive all sins. A goodness that does not conquer every evil is not a perfect goodness, nor is a medicine perfect for which any disease is incurable. It is written in the sacred writings, “Against wisdom, evil does not prevail”; and the omnipotence of our physician is made known by such words in the psalm: “Bless the Lord, O my soul, and all that is within me, bless his holy name. Bless the Lord, O my soul, and do not forget all his benefits—who forgives all your iniquity, who heals all your diseases, who redeems your life from the pit, who crowns you with steadfast love and mercy, who satisfies you with good as long as you live so that your youth is renewed like the eagle’s.” What, I ask, do we think cannot be forgiven us when the Lord forgives all our iniquities? Or what do we think cannot be healed in us, when the Lord heals all our diseases? Or how is there anything still lacking to the healed and justified person whose desire is satisfied with good things? Or how is he not believed to gain the benefit of complete forgiveness to whom a crown is given together with love and mercy? Therefore, let no one despairing of the physician remain in his infirmity; let no one, downplaying the mercy of God, waste away in iniquities. The apostle calls out that “Christ died for the ungodly.”
