Deuteronomy 15:9Meaning & Commentary from the Church Fathers

God, who brought us into existence, bestowed upon us the gift of language so we might unveil the affections of our hearts to each other, enabling each person, due to our social nature, to share thoughts with our neighbors, as if we are drawing treasures from the depths of our hearts. In a state where our souls were unobscured, we could instantaneously grasp each other’s intentions through our thoughts. However, since our thoughts arise from a soul shrouded in a veil of flesh, we must rely on words to express what lies hidden within us. Thus, when our thoughts are accompanied by sounds that represent them, they traverse the medium of words, like a vessel on water, moving through the air from speaker to listener. If the listener is enveloped in silence, then the words find a safe harbor in their ears, much like a vessel in a tranquil dock. Conversely, if turbulence brews among hearers, resembling a violent tempest, the words risk being cast adrift, lost in chaos. Therefore, cultivate silence for these words. There may be wisdom in their cargo. The message of truth is often subtle and can easily elude the inattentive. The Spirit envelops truth in brevity and precision, making it rich in meaning, yet compact enough for recollection. The essence of a word lies in its ability to convey meaning without obscurity, avoiding unnecessary verbosity. This is illustrated in the reading from the books of Moses that I trust you laborers have retained, unless its brevity has caused it to escape your understanding. This message is thus: Guard against a secret word of wickedness in your heart. Humanity tends towards sin through thoughts; therefore, our Creator, who knows the heart (Psalm 32:15), recognizing that most sins originate from the will’s desires, first demanded purity in the realm of our souls. That which is most prone to sin merits the greatest protection. Just as the most skillful physicians safeguard weak bodies through preventive measures, so the great Shepherd of souls has provided strong defenses for our most vulnerable areas. Bodily actions are subject to time, opportunity, the assistance of others, and other external factors; however, thoughts are not limited by time, can arise effortlessly, and are always readily available. Sometimes, an esteemed individual, outwardly displaying virtue and receiving acclaim for their holiness, might be swept away in secret sinful desires within their hearts. They may visualize the objects of their lust, engage in inappropriate mental dialogue, and in the hidden recesses of their hearts, they may indulge in a sin that goes unnoticed by all until the One who uncovers hidden things (1 Cor. 4:5) reveals the intentions of the heart. Thus, be vigilant, lest there be secret iniquity residing in your heart. For whoever looks upon a woman with lustful intent has already committed adultery in his heart (Matt. 5:28); indeed, while bodily actions are encumbered by many hurdles, sinning from the will occurs with alarming swiftness in thought. Thus, where there is rapid decay, there is equally swift means for preservation. For it is declared, ‘Let not a word of wickedness abide in your heart.’ Let us progress to a more profound understanding of this command. It states: Examine yourself. Every creature made by God is endowed with instincts to maintain its existence. Through careful observation, one can observe that many beings without speech inherently evade harm and instinctively pursue what is beneficial. For this reason, our instructing God has entrusted us with this significant commandment, that through reason we may identify what others inherently possess; and that we might pursue what the mute understand instinctively, with deliberate thought and persistent effort, acting as faithful stewards of the motives bestowed upon us by God, fleeing from sin as the mute instinctively shy away from poison, and seeking after truth as they naturally find nourishment in the grass. Therefore, examine yourself to discern between what is harmful and what brings salvation. Since you have the capacity to listen in two ways: either by using your bodily eyes to perceive visible objects, or by employing the mental acuity of your soul to delve into the contemplation of incorporeal realities, if we confine this command to the actions of the eyes, we would readily recognize its impossibility. For how can a person behold themselves with their eyes? The eye cannot perceive its own image; it cannot observe its head, back, or face, nor discern the arrangement of the body’s organs. Yet, it is unjust to claim that the commands of the Spirit are unattainable. Therefore, we must comprehend that this command pertains to mental action. Thus, examine yourself, which entails scrutinizing every aspect of your being; guard your soul’s eye with vigilant attentiveness. Amidst the snares (Sir. 9:18) set by the enemy, there are hidden pitfalls. Therefore, scrutinize all things that you may be rescued like a gazelle from snares, or a bird from traps (Proverbs 6:5). A gazelle escapes the hunters through its keen sight, having been named for its sharp vision. The bird, alert to its surroundings, evades capture by leveraging its swift wings. Thus, be mindful not to be less vigilant than the mute in safeguarding yourself, lest you fall into the devil’s traps, becoming ensnared by his will (2 Tim. 2:26). Therefore, heed yourself; this means focusing not on external matters or what pertains to others, but solely on your own being. The other things reflect who we are; we are soul and mind, created in the image of the Creator; the body and its senses belong to us; our surroundings include possessions, arts, and the comforts of life. Thus, what is the essence of this command? Do not prioritize the flesh, nor chase after corporeal goods such as health, beauty, pleasure, or longevity; do not idolize wealth, fame, or power; do not hold as significant those things that sustain only a fleeting existence. In your pursuit of these things, do not neglect your spiritual well-being. Instead, attend to your soul; nurture it, so that through your diligence, you may ward off any impurities introduced by vice, purify it from sinful disgrace, and enhance it with the beauty of virtue. Examine who you are; recognize that your body is temporary, while your soul is immortal. Our existence is dual in nature: one aspect, belonging to the flesh, is fleeting, while the other, akin to the soul, is everlasting. Therefore, self-examine; do not regard the ephemeral as eternal, nor belittle the eternal as that which fades. Care not for the flesh, which is destined to pass; focus instead on the soul, which will endure forever. With utmost care, nurture yourself to meet both needs: providing sustenance and shelter for the body, while engaging the soul with the principles of piety, honorable conduct, virtue, and the moderation of passions, avoiding an overemphasis on bodily excesses. Yet, since the flesh competes against the spirit, and the spirit against the flesh (Galatians 5:17), ensure you do not give greater authority to the lesser. Just as in weighing scales, if one side is burdened, the opposite side must be lightened; so too occurs with body and soul: excess in one necessitates deficiency in the other. If the body is indulged and becomes weighted down, the mind becomes feeble and unable to carry out its tasks. Conversely, when the soul is nourished and elevated through reflection on what is good, the consequence may be the weakening of physical strength. This commandment is beneficial to both the afflicted and the healthy. When unwell, a doctor advises the sick to be attentive to their condition and to any treatments prescribed. Similarly, the Word, as the physician of our souls, offers healing to the sin-sick soul through this humble guidance. Therefore, listen to yourself, that you may receive healing in accordance with your transgressions. Is your sin great and burdensome? You require extensive confession, heartfelt tears, diligent vigilance, and persistent fasting. Is your sin light and bearable? Let your repentance match its measure. Just be attentive to your soul’s state so you can discern between health and sickness. For many, through neglect, find themselves ensnared in grievous and incurable spiritual ailments, unaware of their condition. This commandment provides substantial benefit to those who are zealous in their endeavors, for it simultaneously heals the ill and perfects the healthy. Each of us, upon receiving this instruction, becomes a servant of the work, as outlined by the Gospel. In this great house, the Church, there exists a variety of vessels, not only of gold and silver, but also of wood and clay (2 Tim. 2:20), along with numerous pursuits. God’s household, which is the Church of the living God (1 Tim. 3:15), includes fishers, travelers, builders, farmers, shepherds, ascetics, and warriors. This simple exhortation fits everyone, instilling diligence in their respective labors and fervor in their purpose. You, a fisherman, sent by the Lord who proclaimed, “Behold, I will send many fishers, and they shall catch them on every mountain” (Jeremiah 16:16), take heed that your catch does not elude you, and that you might bring those ensnared in sin to Christ through the truth. You, a traveler, like the one who prays, “Guide my footsteps” (Psalm 118:133), listen to yourself; do not err from the path, nor deviate to the right or to the left; tread the way of the King. Builder, lay down the foundation of faith, which is Jesus Christ. Ensure, as you build (1 Cor. 3:10), that you do not use wood, hay, or stubble but rather gold, silver, and precious stones (1 Cor. 3:12). Shepherd, heed accurately the duties before you; restore the lost, bind the broken, and tend the sick. Farmer, nurture any barren fig tree to produce fruitfulness. Warrior, engage in the good fight (1 Tim. 1:18) against the spirits of evil, against the desires of the flesh; take up the armor of God (Eph. 6:13), and do not allow yourself to be entangled by worldly distractions, which may please a worldly ruler (2 Tim. 2:4). Ascetic, remain vigilant to not violate the rules of your discipline; for no one receives a crown unless they fight lawfully (2 Tim. 2:5). Emulate Paul, who practiced steadfastness and perseverance. As a good soldier, maintain an undistracted focus; protect yourself from lethal strikes, shielding yourself as necessary. In your race, stretch forth toward the goal (Philippians 3:13) to gain the prize (1 Cor. 9:24). In combat, confront the invisible enemies. The Word requires that you embody this in life, remaining diligent and awake, standing firm for yourself. I could not enumerate the tasks of those who promote the Gospel of Christ, nor the power inherent in this command, which is applicable for all. Listen to yourself: remain sober, be wise, guard the present moment, and consider the future. Do not lose sight of your current blessings through negligence; do not presume to possess what you do not yet have or may never acquire. Is it not folly for youth to lightly presume ownership of what they hope to achieve? Alone or in the stillness of night, they conjure aspirations devoid of substance, allowing errant thoughts to race unchecked, promising themselves fame, ideal unions, prosperity, and long life, full of honors. Unable to ground their hopes, they gravitate toward what society deems most significant. They procure magnificent homes filled with treasures, acquire vast tracts of land as prideful distinctions, and funnel the yield into their coffers of vanity; they amass livestock, numerous servants, civil authority, dominion over nations, command of armies, trophies, and even royal legitimacy. After indulging in ephemeral dreams, they mistakenly believe that their aspirations lie within reach. An idle soul is afflicted by this ailment—being awake to physical reality while entangled in fanciful dreams.

Moses, the esteemed Lawgiver, along with the Holy Spirit, illustrates the purity, clarity, comprehensiveness, and profound creativity of the virtue of sobriety. They instruct us on how to initiate and embody this virtue, stating: “Hearken unto thyself, lest there be a secret word of iniquity in thine heart” (Deuteronomy 15:9). This "secret word" refers to a mental image of a sinful nature that is detestable to God; it is described by the holy Fathers as a justification introduced into the heart by the adversary. Once this thought emerges in our minds, our reflections often become fixated on it, leading to fervent and misguided responses.

On the topic of self-examination, as found in Deuteronomy 15:9, take careful heed to yourselves, trusting and believing that our Lord Jesus Christ, who is divine and possesses immeasurable glory and majesty, set an example for us to follow in His footsteps, as noted in 1 Peter 2:21. He willingly humbled Himself for our benefit, embodying supreme humility as a servant. For our sake, He endured deep humiliation, became impoverished, and faced numerous shameful offenses, fulfilling the prophecy that like a lamb led to slaughter, He remained silent (Isaiah 53:7, 8). Ultimately, He faced a death of profound disgrace for us, so that we, in accordance with His teachings and in recognition of our own transgressions, might willingly endure if we are wrongfully or rightly reproached or slandered.
