While he did not document every detail, he sought to investigate all aspects, recognizing, as John notes, that if one were to chronicle all of Jesus' deeds, "the world itself could not contain the books that would be written" (John 21:25). Thus, Luke purposefully excludes what others have recorded, allowing the various gifts of grace to be illuminated in the Gospel, and ensuring that each account is marked by its own miracles, mysteries, and unique acts.
This Gospel was composed for Theophilus, a name signifying "beloved of God." If you hold love for God within you, then it is intended for you; accept this gift from the evangelist. Guard the bond of friendship closely in the depths of your heart and maintain the good deposit entrusted to you by the Holy Spirit (2 Tim. 1:14). Reflect upon it often and meditate on it continually. Such a commitment first demands faithfulness and then diligence, ensuring that what has been entrusted to you withstands corrosion, as the Lord admonishes against laying up treasures on earth where "moth and rust destroy" (Matthew 6:19-20). The Gospel is a precious deposit; thus, take care not to let corrosion tarnish it within your soul.
When we speak of "moth," it signifies a lack of firm faith in the truths you have read for your own benefit. A moth represents heresy, manifesting in figures like Photinus and Arius. The garment of faith is frayed by those who separate the Word from God. The fabric is torn by Photinus, who misreads, "In the beginning was the Word, and the Word was with God, and the Word was God!" The integrity of the garment remains intact when one acknowledges, "and the Word was God" (John 1:1). The garment is ripped apart by those who proclaim, "This is eternal life: that they may know Thee, the only true God" (Jn. 17:3) without recognizing Christ. Eternal life encompasses not just the knowledge of the Father as the true God but also embracing Christ, the true God of true God. The moth symbolizes a knowledge of Christ devoid of faith in His divine nature and the mystery of His body.
Arius embodies this moth, as does Sabellius. Such heresies assail the spirit of the unbeliever who fails to affirm the unity of the Father and the Son in their divine essence. To fracture the unity expressed in "I and the Father are one" (John 10:30) leads to a grievous division. The spirit that does not recognize that Jesus Christ came in the flesh suffers from this same moth, for it aligns with what the apostle identifies as antichrist (see 1 John 4:3). However, those who are of God (cf. Jn. 1:13) maintain their faith and therefore do not fall victim to the moth that rends the garment, as division, like the kingdom of Satan, cannot endure (Mk. 3:24).
Additionally, the spiritual corrosion may arise when pious intentions become tainted by worldly desires, or the purity of faith is clouded by apostasy. The rust of the soul manifests in the pursuit of wealth, an indifference to spiritual things, and a longing for honors that dominate earthly life. Therefore, as we turn our focus to heavenly matters, we must diligently sharpen our minds and exercise our senses, ensuring the sword that the Lord instructs us to acquire—"buying it by selling our clothes" (Luke 22:36)—is ever with us, bright and ready, sheathed within our souls. Soldiers of Christ must always wield spiritual weapons, empowered by God for the tearing down of strongholds (2 Cor. 10:4), so that the coming Commander of the heavenly host (Nav. 5:14) is not disheartened by neglect of our armament and does not separate us from His army.
