Tantum Ergo Sacramentum

I. Prologue – The Identity and Spirituality of Our Household

Foremost we, the brothers of Tantum Ergo Sacramentum, recognize that Almighty God, out of His superabundant love for us, became Incarnate in the person of Jesus Christ. He is our Sacrificial Lamb of Salvation, who desiring to remain with His Church until the end of time, gave His Body, Blood, Soul, and Divinity to His Church in the Sacrament of the Most Holy Eucharist. While with His disciples, our Lord said to them, “I am the living bread which came down from heaven; if any one eats of this bread, he will live forever; and the bread which I shall give is my flesh for the life of the world” (John 6:51).

It is in His Immaculate Mother Mary, Our Lady of the Eucharist: the Ark of the New Covenant, that our Lord first dwelt bodily. She gave flesh to the Word in the Incarnation, and is always pregnant with that same Word. With love we fly to Her school and to Her patronage, recognizing in Her the most Venerable Mother who delights in teaching and loving Her children.

Inspired by the Holy Spirit, St. Thomas Aquinas eloquently spoke and wrote much about this mystery. The writings of the Angelic Doctor guided the Church in Her Eucharistic devotion, and inspire our love for the Holy Eucharist. St. Thomas Aquinas loved the Holy Eucharist, and knew that it was a mystery that is beyond the senses, and can only be known by faith. In the spirit of St. Thomas Aquinas, we long to contemplate on the truth of this great mystery, and to share the fruits of that contemplation with others.

II. The Purpose and Mission of Our Household

Tantum Ergo Sacramentum, the words of St. Thomas Aquinas meaning “So great therefore is the sacrament,” reflects our love and devotion for the Most Holy Eucharist. We, in obedience to the words of our Lord and the tenants of our faith, commit ourselves wholeheartedly and unreservedly to devotion and service to our Lord in the Most Holy Eucharist, under the motherly guidance of the Ark of the New Covenant. We honor Her and St. Thomas Aquinas as patrons of this household. Flowing from the nature of the household, we also commit ourselves to the liturgy, in which the Incarnate Word mystically re-presents Himself to us. We commit ourselves to constantly labor for true love, reverence, and service to the sacred liturgy, while becoming aware of its many rites in the Church, and to joyfully and worthily partake of these mysteries whenever circumstances allow.

III. The Practical Approach of Our Household

We commit ourselves to pursue holiness by obedience to Christ through true Eucharistic devotion. To this end, we pledge ourselves to fulfill the command we heard from the beginning (cf. 1 John 3:11), that we love one another. Since “we love the brethren” (1 John 3:14), we pledge to edify one another by our words and deeds, to pray together, to foster devotion to the Eucharist and our Blessed Mother among one another, and when prompted by the Holy Spirit, will invite each other to greater holiness in fraternal correction. Tantum Ergo Sacramentum does not exist solely for its individual members, but seeks to serve the broader needs of the campus, its Eucharistic life and devotion, and the liturgical life of the university, while not neglecting our primary vocation as students.

IV. The Fruits of Our Household

As a result of our love for the Holy Eucharist, and our participation in this household, we pray that the Holy Spirit will increase within us the gift of charity, recognizing that “charity is the fulfillment of the law” (Romans 13:10). By our Eucharistic devotion, we hope and pray that we may daily grow in the love of God and of each other, and that our household may be known by the constant acts of love streaming forth from it.

Recalling that our Lord Jesus said of Himself, “I am meek and humble of heart” (Matthew 11:29), we also wish to follow in His way of humility. Through our devotions and common life, we pray that the Holy Spirit will give us ever greater humility as we take up Christ’s yoke.

The psalmist writes, “Be still and know that I am God” (Psalm 46:10). We seek to hear the voice of the Lord in silent contemplation. Entering into this contemplation, we strive to listen to the voice of the Lord in the quiet of our hearts, while being attentive to His call, and heeding His will.

V. Epilogue

We, the brothers of Tantum Ergo Sacramentum, commit ourselves totally and without reserve, both individually and as a household, to complete and total obedience to Holy Mother Church, and to the Supreme Pontiff. We pledge to uphold the Church’s teachings on the Eucharist and the liturgy, and to promote the liturgy as it is offered to us by the Church, especially through the teachings of the Magisterium. May God in His infinite mercy grant us always, through the intercession of Mary, Ark of the New Covenant, and St. Thomas Aquinas, the Angelic Doctor, the grace to keep the faith of the Church, and to live out the promises of this covenant.
