The cathedral of the Bishop of Rome has survived the fall of empires, the displacement of the papal court and seventeen centuries of rebuilding. Its dedication recalls the emergence of public Christian worship under Constantine and the supernatural purpose of every consecrated sanctuary. The ancient Roman Mass, drawing upon Jacob’s vision, the heavenly Jerusalem and Christ’s visit to Zacchaeus, explains why the Church has always regarded the places set apart for divine worship with such particular reverence.
On 9 November the traditional Roman liturgy celebrates the dedication of the Archbasilica of the Most Holy Saviour at the Lateran, better known as St John Lateran. According to the traditional chronology, its original consecration took place in 324 under Pope St Sylvester I, following the construction of a great Christian basilica through the patronage of the Emperor Constantine. The precise date and circumstances of that first dedication are not established with the certainty sometimes suggested by anniversary celebrations, although the Constantinian foundation itself is beyond serious dispute. Seventeen centuries later, the building remains the cathedral of the Bishop of Rome, bearing the title Omnium Urbis et Orbis Ecclesiarum Mater et Caput, Mother and Head of all the churches of the City and of the World.¹
The distinction between the Lateran and St Peter’s Basilica is sometimes overlooked. St Peter’s possesses the tomb of the Prince of the Apostles and has become, through centuries of papal ceremonies, the most recognisable church in Christendom. Yet the Lateran remains the Pope’s cathedral, containing his episcopal cathedra, the visible seat of his authority as Bishop of Rome. The primacy of the Roman Pontiff derives from his succession to St Peter, whose office as visible head of the Church was established by Christ. The Lateran’s particular dignity consequently arises from its association with that apostolic office. The annual celebration of its dedication throughout the Roman Rite expresses the relationship of the particular churches to the Roman See and the visible unity which Christ established within His Church.
The Lateran’s history reaches considerably further back than Constantine. Its name derives from the Laterani, a prominent Roman family whose property passed into imperial possession during the reign of Nero. The area subsequently contained buildings associated with the imperial household and the barracks of the equites singulares Augusti, the emperor’s mounted guards. Archaeological remains beneath the present basilica testify to this earlier occupation, placing the beginnings of the Christian sanctuary firmly within the political and architectural history of ancient Rome.
Following Constantine’s victory over Maxentius at the Milvian Bridge in October 312, and the agreement concerning religious toleration reached with Licinius in 313, the Christian community enjoyed a measure of public freedom which previous generations had frequently been denied. Constantine’s patronage enabled the construction of monumental churches upon a scale previously impossible. On the Lateran estate he caused a great basilica to be erected, dedicated to Christ the Saviour. The familiar association with St John the Baptist and St John the Evangelist developed subsequently, with documentary evidence for the secondary dedications appearing centuries later.²
The original dedication to the Most Holy Saviour deserves attention. The cathedral of the Roman Pontiff was consecrated explicitly to Christ, from whom all apostolic authority proceeds and to whom every act of Christian worship is ultimately directed. The Baptist’s proclamation of repentance and the Evangelist’s testimony to the Incarnate Word subsequently enriched the basilica’s patronage, but neither displaced its fundamental identity. Whatever dignity the Roman See possesses, its authority remains ministerial, exercised under Christ, who alone is the supreme and invisible Head of the Church.
The establishment of the basilica marked a remarkable transformation in the public circumstances of Christianity. The Church had survived nearly three centuries without the protection of the Roman state, enduring periods of persecution and repeated attempts to suppress her worship. Constantine’s patronage permitted the existing Christian community to occupy a prominent place within the architectural life of the capital. The choice of the Roman basilica, familiar as a public hall, provided a structure suitable for the assembly of the faithful around the altar. Its great nave, aisles and apse offered the physical setting for a monumental expression of the liturgy which the Church had already celebrated long before imperial favour made such buildings possible.
The adjoining Lateran Baptistery, substantially developed during the fourth and fifth centuries, completed the sacred complex. Its ancient octagonal form recalls the regeneration of man through Baptism, by which he is incorporated into the Mystical Body of Christ and made a participant in the life of grace. The relationship between baptistery and cathedral is therefore fundamental. The font admits the Christian into the supernatural society established by Our Lord, while the altar nourishes him through the Holy Eucharist and makes present the sacrifice through which his redemption was accomplished.
For approximately a thousand years the Lateran remained the principal papal residence and a centre of ecclesiastical government. Five ecumenical councils assembled there, beginning in 1123 and concluding with the Fifth Lateran Council of 1512–1517. The Fourth Lateran Council, convoked by Innocent III in 1215, occupies an especially distinguished place in the history of Catholic doctrine and discipline. Its first constitution employed the term transubstantiation in teaching the conversion of bread and wine into the Body and Blood of Christ, while its twenty-first constitution prescribed annual confession and Easter Communion for the faithful who had reached the age of discretion. These were matters touching the ordinary spiritual life of Catholics throughout Western Christendom, settled within the very cathedral whose dedication the Church now commemorates.³
The basilica suffered considerably during the succeeding centuries. Earthquakes, fires, military incursions and the prolonged absence of the papal court at Avignon altered its circumstances and damaged its fabric. When Gregory XI returned to Rome in 1377, the Vatican became the preferred papal residence. Nevertheless, the Lateran retained its cathedral dignity, and successive Popes undertook substantial campaigns of restoration. Francesco Borromini’s seventeenth-century reconstruction transformed the interior, preserving the ancient arrangement while clothing it in the architectural language of his own age. Alessandro Galilei’s monumental eighteenth-century façade, crowned by the figure of Christ the Saviour and accompanied by saints, completed another chapter in the history of a building repeatedly renewed without losing its ecclesiastical identity.
The history of the Lateran is consequently an account of continuity through circumstances which have transformed almost everything surrounding it. The Roman Empire which provided the material means for its construction has disappeared. The political order of medieval Christendom, in which the cathedral exercised so prominent a role, has likewise passed away. Even the architectural expression of its sacred purpose has changed repeatedly. Yet the Lateran remains consecrated to the worship of the Most Holy Saviour, and the office of the Bishop of Rome continues through apostolic succession. The liturgy celebrated on its anniversary explains the nature of that continuity more profoundly than any architectural history could accomplish.
The Mass begins with Jacob’s exclamation at Bethel: Terribilis est locus iste: hic domus Dei est, et porta cæli: et vocabitur aula Dei. “How terrible is this place! This is the house of God and the gate of heaven; and it shall be called the court of God.” The patriarch, awakening from his vision of a ladder reaching from earth to heaven, with the angels of God ascending and descending upon it, recognises that he has encountered the presence of the Almighty. His response is reverence, expressed in the setting up and anointing of the stone upon which he had rested his head.⁴
The Latin terribilis conveys the sacred awe appropriate to an encounter with divine majesty. Modern English usage has tended to reduce the word “terrible” to something unpleasant or frightening, whereas the biblical expression describes the fear of God arising from the recognition of His holiness. Jacob understands that he has approached a mystery infinitely exceeding his own nature. He marks the place because God has manifested Himself there, and the memory of that encounter establishes its sacred character.
The Roman liturgy applies his words to the Christian sanctuary, where the divine mysteries are celebrated and the faithful approach the Lord with the reverence which His presence demands. The accompanying verse from Psalm 83, Quam dilecta tabernacula tua, Domine virtutum! — “How lovely are Thy tabernacles, O Lord of hosts!” — joins the awe of Jacob to the longing of the soul for communion with God. Sacred fear and love belong together in the worship of the Almighty. The reverence expressed through bodily posture, silence, ceremonial observance and the fitting adornment of the sanctuary corresponds to the inward disposition of a creature conscious of standing before his Creator.
The ancient rites for the consecration of a church make this understanding visible. The bishop’s procession around the building, the solemn blessings, the tracing of the Greek and Latin alphabets upon the floor, the anointing of the altar and walls with sacred chrism, and the deposition of relics all express the permanent dedication of the place to divine worship. The inscription of the alphabets recalls the universality of the Gospel and the apostolic mission entrusted to the Church. The anointings signify the consecration of the sanctuary, while the relics associate the earthly altar with the martyrs whose fidelity to Christ was manifested through the shedding of their blood.
These ceremonies belong to a religious tradition in which the external forms of worship express objective truths about God and man’s relationship with Him. A consecrated church is permanently assigned to sacred purposes through the solemn action of ecclesiastical authority. Its dignity is founded upon that dedication and the mysteries celebrated within it. The sacred character of the building consequently imposes obligations concerning its use, preservation and treatment. The altar is reserved for the Holy Sacrifice; the sanctuary is ordered towards divine worship; and the faithful are expected to conduct themselves in a manner consonant with the holiness of the place.
The Collect of the feast expresses the meaning of the annual dedication with considerable precision: Deus, qui nobis per singulos annos hujus sancti templi tui consecrationis reparas diem. God renews for His people each year the anniversary of the consecration of His holy temple and preserves them to participate in the sacred mysteries. The prayer asks that those entering the building to seek His benefits may rejoice in obtaining the favours for which they petition.⁵
There is an important theological distinction underlying this language. Almighty God is everywhere present by His immensity, sustaining the whole creation in existence. His presence cannot be confined within walls or restricted to a particular locality. Nevertheless, He has appointed definite means through which men encounter His sanctifying action. The Incarnation supplies the supreme example, for the eternal Word assumed a true human nature through which He accomplished the redemption of mankind. The sacraments communicate grace through sensible signs instituted by Christ, and the Church consecrates particular places for their worthy celebration. The holiness of the sanctuary belongs to this sacramental order, in which created things are employed for supernatural ends.
The Lesson from the Apocalypse (21:2–5) directs the attention of the faithful towards the heavenly Jerusalem. St John beholds the holy city descending from heaven, prepared as a bride adorned for her husband, and hears the proclamation that the tabernacle of God is with men. God Himself will dwell among His redeemed, wiping away every tear, while death, mourning and sorrow will pass away. The imagery belongs to the consummation of salvation, when the communion between God and His saints will reach its perfection in the Beatific Vision.
The direction of the Apostle’s vision deserves consideration. The heavenly Jerusalem descends from God. Its perfection proceeds from the divine initiative and exceeds everything which human effort could accomplish. The Church’s earthly mission is ordered towards that supernatural destiny, and her worship already anticipates the eternal adoration of the heavenly court. The magnificence of a cathedral may express the faith and devotion of those who built it, but the heavenly reality which it represents is God’s own gift.
The liturgy consequently places before the faithful the essential purpose of the Church. Her visible constitution, apostolic ministry, sacraments and discipline exist for the sanctification and salvation of souls. The duties of Christian charity towards one’s neighbour, including the pursuit of justice and the relief of suffering, proceed from the supernatural life of grace and must remain ordered towards man’s ultimate good. The second commandment of the Summary of the Law cannot be understood independently of the first. To love one’s neighbour as oneself is to desire for him the supreme good for which man was created: eternal communion with God. The Church’s works of mercy have always embraced both the corporal and the spiritual precisely because the human person possesses an immortal soul.
This understanding has particular relevance when sacred buildings are increasingly assessed according to their capacity to serve cultural, social or recreational purposes. Churches have certainly contributed to the education, welfare and communal life of successive generations. Their artistic treasures form a substantial part of Europe’s cultural inheritance. Yet such benefits arise from a religious civilisation whose primary concern was the worship of God and the salvation of souls. Once those purposes are displaced, the building may retain considerable historical or aesthetic interest while the reason for its consecration becomes obscured.
The Gradual, Locus iste a Deo factus est, inæstimabile sacramentum, irreprehensibilis est, continues the contemplation of sacred place: “This place was made by God, an inestimable mystery; it is without reproach.” The word sacramentum here belongs to the wider patristic and liturgical vocabulary of sacred mystery. The consecrated building represents the divine work accomplished within the Church, whose members are themselves being formed into a spiritual dwelling for the Almighty.
St Augustine developed this relationship in a sermon preached for the dedication of a church. The material building, assembled from stones and beams, furnished him with an image of the faithful whom God gathers into His spiritual household. Through faith, instruction and Baptism they are prepared for incorporation into the Church, while charity binds them together in the unity of Christ. The construction of the sanctuary therefore becomes an image of the divine work by which souls are fitted for eternal communion with God. Augustine’s interpretation preserves the dignity of the material church while directing the faithful towards the supernatural reality which it represents.⁶
St Peter had already described Christians as living stones built upon Christ, the chief cornerstone (1 Peter 2:4–6). St Paul similarly teaches that the household of God is founded upon the Apostles and Prophets, Jesus Christ Himself being the chief cornerstone (Ephesians 2:19–22). The imagery carries an ecclesiological meaning which ought not to be overlooked. The Church possesses a visible constitution established by her divine Founder. Her members are incorporated into an existing supernatural society through Baptism, and the apostolic ministry exercises the authority entrusted to it by Christ.
The dedication of the Lateran therefore bears directly upon Catholic teaching concerning the Roman primacy. The cathedral’s title, Mother and Head of all churches, expresses its association with the office of the Bishop of Rome, successor of St Peter. The primacy of jurisdiction belongs to that office by divine institution, as taught by the First Vatican Council in Pastor Aeternus and explained by Leo XIII in Satis Cognitum. The Roman See is a visible principle of ecclesiastical unity, and the fidelity owed to the apostolic faith cannot be separated from the constitution through which Christ intended His Church to remain one.⁷
Having considered the holiness of the sanctuary and the divine work accomplished within the living Church, the liturgy turns towards the Gospel with the Alleluia verse from Psalm 137: Adorabo ad templum sanctum tuum: et confitebor nomini tuo — “I will worship towards Thy holy temple, and give thanks to Thy name.” The words make explicit the disposition appropriate to the consecrated place. The faithful enter the sanctuary to render to Almighty God the adoration which is His due, and the Christian fulfilment of that worship is found in the Holy Sacrifice of the Mass. The Psalmist’s thanksgiving also prepares for the Gospel, in which the presence of Christ brings salvation to the household which receives Him.⁸
The Gospel appointed for the Mass introduces a rather different scene. St Luke (19:1–10) recounts the meeting between Our Lord and Zacchaeus, the wealthy chief publican who climbed a sycamore tree in Jericho in order to see Christ passing through the city. Our Lord calls him down and announces His intention of remaining in his house. Zacchaeus receives Him joyfully, and the encounter produces an immediate transformation in his conduct. He promises to give half his possessions to the poor and to restore fourfold whatever he has unjustly taken.
Christ declares: Hodie salus domui huic facta est — “This day is salvation come to this house.” The connection with the dedication of a church is apparent. The presence of the Saviour transforms the household, bringing the grace through which a sinner is reconciled with God. Zacchaeus receives Christ into his home, and his repentance finds expression in restitution and charity.
The selection of this Gospel is particularly instructive because it associates the sanctity of a building with the saving action of Christ. The Christian sanctuary is consecrated for the celebration of those mysteries through which Our Lord continues to communicate the fruits of His redemption. Its altar is the place of sacrifice, its font the place of regeneration, and its confessional the tribunal of mercy. The holiness of the building serves the sanctification of those who enter it, and the faithful are called to receive the divine gifts offered there with the dispositions which those gifts require.
Zacchaeus also reminds the Christian that genuine conversion entails amendment of life. His encounter with Christ does not leave his former conduct undisturbed. He recognises obligations of justice towards those whom he has defrauded and accepts the necessity of reparation. The Gospel therefore brings the solemnity of the dedication into the practical circumstances of Christian morality. Divine grace produces its fruits in the conduct of those who cooperate with it.
The scene has another significance when read alongside the Introit. Jacob encountered the Almighty through an extraordinary vision and recognised the place as the gate of heaven. Zacchaeus encountered the same divine Majesty under the ordinary human appearance of Jesus of Nazareth. The Incarnation has brought God among men in a manner which surpasses the manifestations of the Old Testament. In the Holy Eucharist, the same incarnate Lord makes Himself present beneath the sacramental species, offering His people a participation in the sacrifice by which He redeemed them. The reverence which Jacob displayed at Bethel finds its Christian fulfilment before the altar of the New Covenant.
The Offertory is taken from the First Book of Paralipomenon (29:17–18), where David rejoices over the offerings assembled for the construction of the Temple: Domine Deus, in simplicitate cordis mei lætus obtuli universa. “Lord God, in the simplicity of my heart I have joyfully offered all these things.” David acknowledges the generosity of the people and prays that God will preserve their willingness to give. The Temple is to be constructed through the offerings of Israel, whose gifts are returned to the Lord from whom every blessing proceeds.
The passage has an obvious relationship to the Christian tradition of constructing and maintaining churches through the sacrifices of the faithful. Great cathedrals and modest village sanctuaries alike have been raised through the generosity of generations who understood the provision of a fitting place for divine worship as an obligation of religion. The offering of material resources for the honour of God has a history extending through the whole Christian dispensation, and frequently reveals more about the convictions of the faithful than their written declarations.
The purpose of such generosity remains the sacred action celebrated upon the altar. The Eucharistic sacrifice makes sacramentally present the one sacrifice of Calvary, through which Christ accomplished the redemption of mankind. The marble, stone, gold and silver employed in a sanctuary possess their proper dignity through their association with divine worship. Their beauty reflects the desire to offer to Almighty God what is worthy of His majesty, while their religious value derives from the mystery which they serve.
The Secret asks that the prayers and offerings made before God may obtain, through His assistance, the eternal rewards towards which the faithful aspire. The petition again directs the liturgy towards the supernatural destiny of man. The generosity of David and the offerings of Christian worship find their proper place within the divine economy of salvation.
At Communion the text returns explicitly to the identity of the sanctuary: Domus mea domus orationis vocabitur, dicit Dominus — “My house shall be called the house of prayer, saith the Lord.” The antiphon joins Our Lord’s words concerning the Temple with His promises that those who ask shall receive, those who seek shall find, and those who knock shall have the door opened to them.
The reference recalls Christ’s cleansing of the Temple, when He drove out those who had turned His Father’s house into a place of commerce. His indignation arose from the misuse of a sanctuary reserved for divine worship. The Christian understanding of sacred space has inherited this concern, now deepened by the mysteries of the New Covenant and particularly by the Real Presence of Our Lord in the Blessed Sacrament. The reservation of the Eucharist places a Catholic church under an obligation of reverence which cannot be explained by architectural merit, historical importance or the preferences of those who use the building.
The Church’s traditional discipline concerning sacred buildings follows from this understanding. A consecrated sanctuary possesses a permanent religious purpose, and activities conducted within it must be judged according to their compatibility with that purpose. Its designation as the house of prayer carries consequences for the conduct of clergy and faithful alike. The atmosphere of worship, the observance of sacred silence, the preservation of appropriate ceremonial and the dignified treatment of the altar all express recognition of the Lord whose presence sanctifies the place.
The Postcommunion provides a particularly fitting conclusion to the Mass: Deus, qui de vivis et electis lapidibus æternum majestati tuæ præparas habitaculum. “O God, who from living and chosen stones preparest an eternal dwelling for Thy majesty.” The prayer continues by imploring God’s assistance for His suppliant people, that whatever enlargement the Church receives in her material buildings may be accompanied by a corresponding increase in her spiritual life. Here the Augustinian interpretation of the dedication finds its fullest liturgical expression. The building serves the salvation of those whom God is preparing for His eternal habitation.⁹
The Mass therefore presents a coherent theological account of consecrated space, drawing together the sanctuary of the Old Testament, the sacramental worship of the Church and the heavenly Jerusalem towards which the faithful journey. It explains why the Church has devoted such care to the construction and consecration of her churches, and why their sacred character has traditionally governed the manner in which they are used. The dignity of the sanctuary arises from its relationship to divine worship, while the spiritual purpose of that worship is the sanctification of the faithful.
The Lateran possesses its own singular place within this understanding because it is the cathedral of the Roman Pontiff. Its association with the apostolic office of St Peter gives the dedication a universal ecclesiastical significance, although the supernatural mystery celebrated there is the same Holy Sacrifice offered upon every Catholic altar. The smallest consecrated chapel shares in the essential purpose for which Constantine erected his basilica, even when it possesses none of the historical distinction or architectural magnificence of Rome’s ancient cathedral.
There is something instructive in the survival of the Lateran through the successive transformations of European civilisation. The imperial authorities who first patronised its construction have long since disappeared. The medieval Papal States, the political structures of Christendom and the social conditions which sustained them have passed into history. The cathedral has repeatedly been altered according to the architectural preferences of different generations. Yet the reason for its consecration remains intelligible wherever the traditional Roman liturgy is celebrated and the Catholic faith concerning the Eucharistic sacrifice is professed.
The final promise of the Lesson from the Apocalypse, Ecce nova facio omnia — “Behold, I make all things new” — concerns the heavenly Jerusalem, where the redeemed will enjoy that perfect union with God towards which the Church’s earthly worship is directed. The Lateran itself belongs to the passing order of this world. Its ancient stones, however venerable, will one day have fulfilled their purpose. The communion of saints which they presently signify belongs to the eternity for which God created and redeemed mankind.
