The Church Fathers on this verse

8 Church Fathers comment on this verse

Augustine of Hippo

5th centuryChurch Father

You have listened to the psalm, dear friends, while it was being sung: it is concise and somewhat elusive: as if I had offered you a promise that you need not fear exhaustion. The title of this psalm is ‘A Psalm of Confession.’ While the verses are few, they touch upon profound themes; may the seeds of these words take root in your hearts, and may the storehouse be ready for the harvest from the Lord. Therefore, rejoice in the Lord, all the earth, as stated in Psalm 99:1. This psalm encourages us to delight in the Lord. It does not merely call upon one specific part of the earth or a single gathering of people; instead, it recognizes that it brings forth good things universally, instilling joy across the globe. Does the entire earth hear my voice at this moment? Yet indeed, the whole earth has heard this message. The entire world is already rejoicing in the Lord, and those yet to find joy will also do so. For the blessings that spread throughout the world began when the Church moved from Jerusalem to all nations, as in Luke 24:47; everywhere it overcomes wickedness, nurturing righteousness in every land. Each country is awash with the discontented murmurs of the unrighteous and the jubilant praises of the godly. What, then, is the cause for our joy? The title of this Psalm invites us to heed this message, for it is labeled ‘A Psalm of Confession.’ What does it mean to rejoice in acknowledgment? This sentiment is echoed in another psalm: Blessed are the people who know how to rejoice. Surely, that which understanding brings joy to is something profound. Therefore, let us seek from the Lord our God, who imparts blessings to humanity, to enlighten our speech and your understanding of His words: Blessed is the people that understands rejoicing. Let us come to this blessing and truly grasp the essence of celebrating, not simply voicing joy without comprehension. What value is there in shouting ‘Rejoice in the Lord, all the earth,’ if we fail to grasp the meaning of our exultation, rendering it mere sound without heartfelt conviction? For understanding is the voice of the heart.

I will express a truth that you already know. One who rejoices does not articulate merely spoken words, but rather expresses a certain joyful sound beyond words; it is the heart's outpouring in delight, conveying affection as best as possible without being bound by sensory experience. A person rejoicing in their own elation, may momentarily launch into expressions that defy verbal understanding, bursting forth with inexpressible joy, so it may seem they are merely celebrating the sound of their own voice, but rather they are overwhelmed with joy that transcends mere words. Those who are most inclined to rejoice are often laborers in the fields—those harvesting grain, gathering grapes, or collecting the fruits of the earth. They revel in the bountiful harvest and the richness of the soil, letting their songs burst forth, mingling heartfelt shouts of joy amidst their words.

When do we truly rejoice? When we offer praise that transcends articulation. For we observe the entirety of creation, the earth and the sea, and all that dwells within them: we see each has their own source, lifecycle, and end—all running their course in succession, with stars appearing to travel across the sky, completing their yearly journey; we see months and hours measured out; and within these observations, there lies some unseen element, a principle of unity, often identified as spirit or soul, present in all living beings, driving them toward pleasure, away from pain, and ensuring their own safety. Humanity shares a connection with the angels of God—not merely with animals, but with that aspect of our being capable of understanding God, which is uniquely tied to our reasoning, enabling us to discern righteousness from wrongdoing, just as our eyesight distinguishes colors. In contemplating creation, let us ask ourselves: Who is the Creator of all that exists? Who gave rise to all things? Who among them created Himself? I have examined creation to the best of my ability, discerning both the physical creation of heaven and earth and the spiritual aspect within myself, which articulates, animates my body, expresses through my voice, and perceives sensations. When can I truly grasp myself? If I find it difficult to understand myself, how can I comprehend that which surpasses my understanding? Yet humanity is promised the vision of God, and Scripture provides guidance for the purification of our hearts. Strive to see what you love before you can attain the vision. For who wouldn’t be pleased to hear of God and His name, save for the wicked among us who are distanced from Him?

Therefore, strive to emulate Him in holiness, and be diligent in your reflections; His invisible attributes are evident to all, being perceived through creation, as Romans 1:20 expresses. Observe His creations, admire them, and seek the Creator. If you are not aligned with Him, you will regress; if you are, you will rejoice. As you grow closer to Him, you will feel God’s presence within you, and as love—since God is love—grows in you, you will grasp something you have long sought to articulate but cannot fully express. Before experiencing God, you believed you could describe Him; but once you feel Him, you understand that what you perceive is beyond words. Will you remain silent when you realize that such profound feelings cannot be articulated? Will you refrain from praising God and offering thanks to Him who wished to make Himself known to you? You sang His praises in seeking Him; will you go silent upon finding Him? Certainly not; you will not be ungrateful. He deserves honor, He is worthy of reverence, He is deserving of great adulation. Reflect upon your own state; see who you are: mere dust and ashes; ponder who truly merits admiration; consider the wonder of man—seeing God! I recognize not merely the worth of this man, but the mercy of God. Therefore, praise Him who is merciful.

Serve the Lord with gladness. All servitude is filled with bitterness; those bound in considerable servitude are slaves and discontented. Do not fear the servitude of the Lord of Hosts; there exists no groaning, no resentment, no bitterness there; for no one wishes to be transferred to another master, for this servitude is a sweet grace, as we all have been redeemed. It is a great joy, my dear friends, to be a servant in that great household, even while in chains. Fear not, bound servant; rejoice before the Lord: attribute your chains to your own shortcomings; acknowledge your bonds, if you wish them to become your adornments. You are at once a servant and yet free—the servant by creation, free because you are cherished by the God who created you; indeed, you are truly free if love for Him consumes you. Do not serve with discontent; for your grumbling will not free you, but make you a wicked servant. You are the Lord’s servant, yet His freeman; seek not to escape His household, for He is the One who sets you free.

Now, he might say, I will live separately with a select few virtuous individuals; why should I stay among the masses? But from what crowd have these few selected individuals emerged? If all among them are virtuous, it is indeed commendable for someone to seek tranquility with those choosing a quieter existence, away from the tumultuous throngs, akin to being in a harbor. But is that the joy that has been promised? Not yet; rather, anxiety and the groans of temptation are present. For even a harbor has its entrance; otherwise, no vessel could dock there; thus it must have some opening, from which the wind may rush in; and where there are no rocks to protect a vessel, collisions inevitably occur. So where then is the safety if a harbor too is not secure? Nonetheless, it must be acknowledged that those in the harbor are indeed in a better position compared to those adrift in the open sea. Let them love each other like ships anchored in the harbor, let them find happiness together, striving for harmony and maintaining steadfast love; yet when the winds come from the open side, they must be vigilant in their navigation. What will someone say to me who presides over such places, serving in the so-called monastic life? I will take care; I will prevent any wrongdoing. But how can you assure there will be no evil? Those about to enter do not even know themselves; how much less can you truly comprehend them? Many have promised themselves that they will strive for that holy existence, where all things are shared, and no one claims any possession as his own, with hearts united in God, as Acts 4:32 illustrates, only to falter when they face trials. How, then, can you know another who is a mystery even to themselves? Where then is safety? In this life, indeed nowhere—only in the hope placed in God’s promises. Yet once we arrive at that promised land, security will be complete, once the gates of Jerusalem are locked; there we will find perfect joy. Do not presume to praise any life; judge no one blessed before their completed journey.

Thus individuals are led astray, either shunning a better life or recklessly pursuing it; and those inclined to criticize often do so from a perspective filled with envy and malice, overlooking the good and emphasizing only perceived evils. Thus, when a vocation is maligned, that is, received carelessly despite its reputation, those entering may encounter what they did not expect; and one offended by unrighteousness may turn away from the righteous. Dear friends, apply this teaching to your own lives, and heed it so you may truly live. The Church of God stands elevated; Christians alone are labeled as great, the Catholic Church is exalted; love for one another prevails; each performs acts of kindness for one another, dedicating themselves to prayer, fasting, and worship; in peaceful harmony across the earth, God is praised. Perhaps someone listens who fails to recognize that these praises do not include the wicked intermingled among them; and being drawn by such commendations, they arrive only to discover unrighteous individuals within, whom they were not warned of prior to their arrival. They become offended by false Christians and withdraw from true believers. Conversely, those who harbor animosity and slander quickly rise to accuse: What kind of people are Christians? What sort of individuals are Christians? Selfish, greedy. Are not those who fill the churches on feast days the same who flock to theaters and arenas for entertainment? They may indeed be gluttons, drunkards, envious, backbiters. And while that is true, they are not the only ones. But the one who slanders, in blindness, speaks of none of the good, while the careless critic overlooks the bad.

Theodoret of Cyrus

5th centuryChurch Father

Is it not right to exalt Him who has demonstrated boundless compassion and who accomplishes the fulfillment of His promises? What He assured our forebears, He has brought to fruition in our time, and has truly bestowed the salvation that was pledged.

Euthymios Zigabenos

11th centuryCommentator

Worship, he declares, the name of Christ; for He is both good and full of compassion. His mercy is everlasting, unlike that of humanity, which is fleeting; and the truth of Christ's words endures, extending not only to the ancient Jewish people but also to the new Christian community. Eusebius writes: Acknowledge Him as a healer, unveiling the wounds of the soul through the confession of sins. Approach this with courage, as those who have embraced the undeniable teaching that He is good and His mercy is infinite. Isychias states: Because He is good, meaning compassionate and merciful, He has bestowed grace in our current age, so that if we stumble through carelessness, we might return to Him through His human nature. The truth of God, which began in this generation, will also be manifested in the generations to come, when He will reward each individual according to their actions. This remains an undeniable and unchanging truth.

Hesychius of Jerusalem

5th centuryChurch Father

His truth, which has manifested in this generation, will also be revealed in times to come, when He will give to each individual based on their actions. This undeniable and irrefutable truth is that Christ is ‘the Lord, for evermore His mercy’; because as Christ—embodying compassion and grace—He offers His mercy in this life, allowing us to turn back to Him in our humanity if we happen to stray due to negligence.

Ignatij (Briantchaninow)

19th centuryChurch Father

How wondrous is the Lord, for His mercy endures forever, and His truth remains through all generations. Through understanding and acknowledging God's righteousness, and the justification of His decrees (Psalm 18:10), the devotee of prayer gains insight into the boundless goodness of God, which is inseparable from His righteousness. In this union of divine goodness and justice lies His holy truth: mercy and truth are intertwined, as are truth and peace (Psalm 84:11). From the prayer of one who prays with purity, a spiritual sweetness emerges from the recognition of God's goodness, which immerses the human spirit in profound humility, simultaneously elevating it from the earth to the heavens. Such a person of prayer embodies solitude and silence.

This silent soul dwells continually in the presence of God through His work within him, detached from the world and free from concerns over temporal matters. The heart, awakened by its love for God and all that pertains to Him, becomes dead to the world and to all that opposes or deviates from God. In this death, there is life; in this death, there is salvation. Amen.

Irenaeus (Klementjewsky)

18th centuryCommentator

This conclusion parallels the opening lines of the psalm, though it emphasizes the ceremonial law by stating that the faithful ought to express gratitude to God for His blessings solely through a solemn declaration of piety and faith. When referring to the gates and entrances of the temple, it indicates that God desires to be revered by His people in accordance with the directives of the law. To remind us of our ongoing obligation to honor and exalt God, it is declared that His mercy is everlasting and His truth remains steadfast throughout all generations. Given that God consistently shows this disposition toward us, it would be shameful and disgraceful not to express our thankfulness by fulfilling our duty of praise and exaltation.

In this passage, the Prophet outlines three key attributes of God, presenting them as critical reasons for glorifying Him: His goodness, mercy, and truth. These traits are intricately connected, each stemming from the others. Since God is good, He is also merciful; and because He is merciful, He is true, meaning He is faithful to His promises. However, reconciling these gentle attributes with the awe-inspiring majesty of God, who resides in unapproachable light and is feared above all deities, creates a seeming contradiction. The Apostle highlights this when stating, ‘It is a fearful thing to fall into the hands of the living God’ (Hebrews 10:31).

This apparent paradox can be understood as follows: God is benevolent to those with upright hearts who revere Him, yet He is fearsome to those with corrupt hearts who scorn Him. David acknowledges in Psalm 72:1 that the God of Israel is kind to the righteous, while to the morally corrupt, what appears smooth feels harsh and opposing. Those who are wicked and deceitful in heart resist the righteousness of God's will and include those who blaspheme and disregard Him.

Thus, it is stated about the righteous: just as a father shows compassion to his children, so the Lord shows mercy to those who revere Him (Ps. 102:13); and: the mercy of the Lord is from everlasting to everlasting for those who fear Him (Ps. 102:17). In contrast, it is believed that anger and distress will come upon every soul that practices evil (Rom. 2:8, 9). Therefore, if anyone, following the path of the righteous, begins to align their heart with God's will and fears nothing more than to provoke His anger, they will quickly experience the goodness of the Lord, discovering that His mercy endures forever and His truth persists through all generations.

Ireneus (Orda)

19th centuryCommentator

The Psalmist invites Israel to express profound gratitude to the Lord, who, in His boundless compassion, has selected Israel from all other nations and consistently guides them with kindness. Such a divine being is worthy of exaltation in His sanctuary. In our expressions of confession and thankfulness, we engage in acts of worship through sacrifices and hymns of praise. The phrase "that which He made us" pertains not to our creation but to our divine selection; He has transformed us into His chosen people, the stewards of His promised land.

Psalter with Commentaries (Cave Monastery in Kiew)

19th centuryCommentator

Psalm, influenced by the Holy Spirit through David, serves as a profound expression of God's glory. Just as the confession of sins must stem from a sincere heart, so too must the acknowledgment of God's magnificence arise from the heart, soul, and mind in totality. Urging all toward this acknowledgment, the prophet fervently proclaims the brilliance of God's splendor, particularly His abundant mercy manifested in Christ the Lord, who is revealed to all humanity: so that every tongue may profess that Jesus Christ is the glory of God the Father (Philippians 2:11). The term "earth" is symbolically used to refer to mankind. This appellation was conferred upon Adam by God: you are dust (Genesis 3:19).

The entirety of creation—the whole human race—should express gratitude to Christ God, the Savior of the world. In Christ, a new creation is born of water and the Spirit, and one who has not been reborn through baptism cannot enter the Kingdom of Heaven, where the veins, akin to angels, will dwell. To serve God with cheerfulness fulfills His commandments well; one should enter the Lord's church with joy, for therein lies the feast of salvation for the faithful. The service of the Lord is imbued with joy and gladness, for His reign is tender and compassionate. Through Christ, the faithful are embraced as children of the Father, crying out, "Our Father, who art in heaven." And where the Father resides, there also dwell the children, for the homeland of the children is in heaven, where the Heavenly Father dwells. God is the Creator of humankind, while parents act merely as contributing factors to birth; both Job and David, though born of earthly parents, declare: "Your hands made me and formed me" (Psalm 118:73; Job 12:9). To Jeremiah, God states, "Before I formed you in the womb, I knew you" (Jeremiah 1:5). No rational being possesses inherent authority; rather, all serve their Creator God in humble submission. We are His people under His Kingship and His sheep under His Shepherd. The true God, Jesus Christ, is present in the Most Pure Mysteries. He is the Creator and Sustainer of all, the Shepherd to the faithful, and the Body and Blood of Christ. The claims of the Pharisees and the purveyors of contemporary theories that mankind evolved from primates and that the universe is millions of years old are falsehoods.
