Matthew 16:18Meaning & Commentary from the Church Fathers

Each one of us is part of the church, which is the dwelling place of God. If we remain steadfast in our confession of Christ, the gates of hell—symbolizing our sins—will not triumph over us. In reference to this deliverance, David expressed, "He that lifteth me up from the gates of death," Psalm 9:14. From which gates was David lifted? From two in particular: murder and adultery.

The Lord Himself foretells, stating: “Thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it” (Matt. 16:18). In this context, He identifies the gates of hell as those who seek to harm the Church, likening them to devastation and ruin, leading many into the chains of despair. Therefore, adversaries of the Church will ultimately be weakened, faced with destruction and judgment; for it is affirmed that “many are the afflictions of the righteous, but the Lord will deliver me out of them all” (Ps. 33:20). Indeed, it is stated that “all who desire to live godly in Christ will be persecuted” (2 Tim. 3:12), yet Christ neutralizes the intentions of the wicked and renders their efforts ineffective. He bestows upon us the “power to tread upon the serpent, and upon the scorpion, and upon all the power of the enemy” (Luke 10:19). He encourages us further with the promise, “in the world you have tribulation, but take courage; I have overcome the world” (Jn. 16:33).

When Jesus gazed at him, He declared, “You are Simon, son of Jonah; you are called Cephas” (Jn. 1:42). Peter acknowledged, “He who sees hearts and wombs is the Godly One” (Psalm 7:10; Jeremiah 11, etc.). The Lord perceives the level of devotion and the moral excellence the disciple will achieve, for He is “He that knoweth all things before they were” (Dan. 13:42). This emphasizes that Jesus, being the true God, possesses divine knowledge without the need for instruction; without uttering a word or inquiring about Simon’s origins, He identifies him and his destiny. Having claimed him as His own, He renames him Peter, a name signifying ‘rock’ (πέτϱα), intending to establish His Church upon him.

Let us further explore how the Saint elucidates Matthew 16:18: “For Christ is the foundation and steadfast support of all things, governing and sustaining creation, ensuring its firm establishment. Through Him, we are constructed into a spiritual dwelling, united harmoniously by the Holy Spirit within the sacred Church, as He resides in our hearts through faith” (Eph. 2:21, 22; cf. Eph. 4:16). The Apostles and Evangelists, who were witnesses and servants of the Word (Lk. 1:2), were affirmed and grounded in faith, serving as models for us. By adhering to their teachings, we maintain an authentic belief in Christ without distortion. As stated by Christ to the Divine Peter—who boldly confessed, “Thou art the Christ, the Son of the living God”—He affirmed, “Thou art Peter, and upon this rock I will build My Church,” indicating that the rock symbolizes the unwavering fidelity of the disciple.

In summary, St. Cyril of Alexandria interprets ‘rock’ not as Peter himself, but rather as his FAITHFULNESS, equated with confession in the faith.

Blessed Augustine, who is regarded as the architect of Western Christian theology, expounded on this in his teachings. He articulated that the Church is established on the solid foundation from which Peter derives his name, paralleling how the term "Christian" is rooted in "Christ." This foundational stone is Christ Himself, as asserted in the scripture: “For they drank from the spiritual rock that accompanied them, and that rock was Christ” (1 Cor. 10:4), and “For no one can lay any foundation other than that which is laid, which is Jesus Christ” (1 Cor. 3:11). Augustine further explains that the creed of the Apostle Peter functions as this cornerstone, emphasizing that the Church is built by Christ not upon a singular individual but upon this foundational belief.

In his teachings, Augustine highlights the significance of Peter's confession as emblematic of the Church. It represents a collective unity rather than the position of a solitary leader. According to Augustine, while Peter embodies the Church in his acknowledgment of Jesus' divinity, the keys to the Kingdom of Heaven were entrusted not to an individual but to the unity of the Church. This perspective underscores that Augustine does not perceive Peter as merely the head or sole authority of the Church, but acknowledges Peter's prominence within the broader context of the Church's mission and integrity.

When referring to the gates of hell, I indicate the vices and sins, or indeed, the erroneous teachings of heretics, which lead the unsuspecting into the abyss. Let no one presume that this speaks solely of death, as if the apostles were exempt from its realities, for their radiant martyrdom is a testament to their triumph.

Ambrose articulates that if Peter is deemed the foundation, then all apostles share this foundational role; if the Church is built upon him, it extends even more so to the others. Peter is united with Christ, echoing the Lord's words to his disciples: “You are in me, and I in you” (John 14:20). Christ stands as the foundational rock for all His apostles, who, in turn, build the faith of many who believe through them.

This perspective finds echoes in the reflections of Priest Anthony of Odai on St. Ambrose's teachings. Ambrose outlines faith as the true foundation of the Church, underscoring that the gates of hell cannot overcome it (non enim de carne Petri, sed de fide dictum est, quia portæ mortis ei non prævalebunt). He identifies Christ as the Rock, inspired by the Apostle Paul's assertion about the spiritual nourishment from Christ (1 Cor. 10:4), urging Christians to cultivate their internal steadfastness—building their spiritual house on the rock of faith, which represents their actions and thoughts.

This allegorical interpretation discourages viewing Peter as the sole foundation, emphasizing Ambrose’s well-known declaration: “Where Peter is, there is the Church” (Ubi Petrus, ibi Ecclesia), which should be understood as a representation of the episcopacy embodied in each bishop, reflecting the fullness of the Petrine gift in building the Church.

Peter confidently professed, “You are the Christ, the Son of the living God” (Matt. 16:16), asserting His eternal existence. The Savior graciously entrusted His titles to His disciples, stating “I am the light of the world” (Jn. 8:12) and reflecting it in, “You are the light of the world” (Matt. 5:14). Additionally, He called Himself the bread of life (Jn. 6:51), while instilling in His disciples a sense of unity in the faith (1 Cor. 10:17). Christ is the true vine (Jn. 15:1), yet assures His followers they are part of that eternal vine (Jer. 2:21). Christ is indeed the Rock, as from Him flows the life-giving spiritual sustenance (1 Cor. 10:4), yet Peter is also deemed a rock because of his steadfast faith that mirrors Christ's strength.

Aspire to be a rock—seek not your foundation externally but within! Your rock lies in your deeds and thoughts. Build your house upon this foundation; it will remain unshaken by the storms of malevolence (cf. Matt. 7:24; 16:18; Lk. 6:48; Eph. 6:11). Your faith serves as the foundation of the Church. If you embody this rock, you are part of the Church, which is built upon the rock, ensuring that the gates of hell cannot conquer you. The gates of hell symbolize death (cf. Matthew 16:18; Psalm 106:18) and cannot be associated with the Church.

The gates of death, or hell, encompass sin. Engaging in adultery leads you to those gates. Violating a promise brings you closer to death’s domain. Committing a mortal sin opens these gates. Yet, God possesses the power to rescue you from death’s grasp, allowing you to proclaim His goodness at the gates of salvation (cf. Psalm 9:15). The entryway of the Church, on the other hand, is through righteousness and purity. The righteous enter, declaring, “Open unto me the gate of righteousness; I will enter and give thanks to the Lord” (Psalm 117:19).

In contrast to the gates of hell, the gates of righteousness represent access to divine grace, for the righteous shall enter through them (Psalm 117:20). Take heed to avoid a life of sin, lest you fall prey to the gates of hell (cf. Matt. 16:18). Should sin establish its reign over you, it will darken your path and lead you to death. Therefore, refrain from quarreling and strife (cf. 2 Cor. 12:20; Gal. 5:20) and the tumult of discord, avoiding the gates of death. For initially, the Lord Jesus preferred to remain silent and not provoke public disputes.

Consequently, the wise Apostle Paul, renowned for his church-building efforts, emphasizes that no other foundation can be laid except that which is established, which is Jesus Christ (1 Cor. 3:11). Both this divine author and Blessed Theodoret recognize Christ as the cornerstone of the Church. While the patrology of Minya does not contain Blessed Theodoret’s original letter, it does include a description of it.

This understanding aligns with the teachings of Priest Anthony of Odai in his ‘Holy Theological Interpretation of the Gospel of Matthew 16:18.’ Saint Epiphanius of Cyprus, an ardent opponent of heresy, draws connections between the Apostle Peter and his faith. On one hand, he identifies Peter as the principal Apostle and the solid rock on which the Church of God stands. Conversely, he asserts that "Saint Peter, the chief among the apostles, has become a true firm rock, affirming the Lord's Faith, upon which the Church is built in all respects." Additionally, St. Epiphanius references Matthew 16:18 to elucidate the Lord’s words following Peter’s proclamation: “On this rock of steadfast faith I will build my Church.” He perceives the apex of the apostolic tradition not solely in Peter’s person but within the Creed, which the fathers of the Council of Nicaea proclaimed, affirming that “This faith was entrusted to us by the holy apostles and ratified in the Church in the holy city in a unanimous agreement by all the then-assembled holy bishops, totaling more than three hundred and ten.”

This interpretation draws from Priest Anthony of Odai's work 'The Holy Theological Interpretation of the Gospel of Matthew 16:18.' The Venerable Hilary of Pictavius, known as 'Athanasius of the West' for his vigorous defense of Orthodoxy against Arianism in Gaul, regards the rock upon which the Church is established as a solid affirmation from the mouth of Blessed Simon Bar-Jona. The unshakeable foundation, he notes, is the proclaimed rock of Peter’s blessed faith.

Thus, despite the Empire’s collapse, the relocation of its capital to Constantinople, and barbarian invasions, the core of eternal Christian unity was expected to remain steadfast as a ‘stone,’ represented in the universal pastoral authority of the successor of St. Peter in Rome: ‘Through the holy pulpit of the blessed Peter, you (Rome) by the worship of God have attained a more extensive power than through earthly authority.’ The trials faced by the eternal city throughout history only furthered the unfolding of God’s plan, affirming Rome's role as the unyielding voice of the Vicar of St. Peter: ‘What Truth itself has commanded abides, and therefore the blessed Peter, retaining the power of the rock which he has received, does not abandon the government of the Church entrusted to him.’ This substantial divergence in understanding and applying the Gospel text, particularly the term 'stone,' stands out as uncommon and misaligned with the broader tradition of holy theological interpretation. Thus, St. Leo the Great’s perspective may be seen as a personal theological viewpoint.

A second testimony can be sourced from the book of Revelation, authored by St. John the Theologian, which prophetically outlines the future of the Church of Christ until the end of days (Rev. 6:7, 11, 12, 19-21). Notably, even amidst the darkest trials the Church may face, the vision reveals her as miraculously safeguarded from harm. For instance, the serpent pursuing the woman fails to capture or defeat her, as ‘two wings of a great eagle were given to the woman,’ and ‘the earth helped the woman’ (Rev. 12:13-16). Divine Providence orchestrates circumstances such that even secular powers contribute to the peace and security of the Church; the wings of the ‘great eagle’ graciously lift her above the malice and cunning of her foes, ‘into the wilderness to her own place’ (Rev. 12:14). This ‘own place’ is not merely a physical desert but represents a deeper spiritual ‘wilderness’—a realm removed from worldly distractions and drawn ever closer to God; for the Church’s true ‘own place’ lies in her intimacy with God and communion with Him.

A third testament to this enduring truth is found in the epistles of the holy Apostle Paul. Addressing the longevity of spiritual leaders within the Church ‘for the perfecting of the saints, for the work of the ministry, for the building up of the body of Christ,’ he responds that this will continue ‘until we all come into the unity of faith and of the knowledge of the Son of God, into perfect manhood, into the measure of the full stature of Christ’ (Eph. 4:11-13). Therefore, as long as there are still those on earth who have yet to reach unity in faith, have not attained spiritual maturity, or are in need of the knowledge of the Son of God, there will remain in the Church shepherds and instructors dedicated to the perfecting of the saints.

This assertion gains particular significance as, despite Eusebius's doctrinal ambiguities and some rigidity at the First Ecumenical Council, he clearly affirms the belief in Jesus Christ and His divine nature as the Church's foundation, thereby reflecting a widely accepted perspective within the early Church.
