THE VICENTIAN PRINCIPLE: BEACON OF FAITHFULNESS AND GUARDIANSHIP OF THE ETERNAL FAITH

“In the Catholic Church, we must take the utmost care to hold fast to what has been believed everywhere, always, and by everyone.”

— St. Vincent of Lerins, Commonitorium

St. Vincent of Lerins’ declaration is not just a theological formula; it is a hymn to the stability of the faith amidst the storms of history. This principle not only guides the intellect in doctrinal discernment but also touches the heart of the believer with the certainty that by remaining faithful to what has always been believed, we walk in the light of eternal Truth.

It is not merely a technical rule or a pragmatic tool; it is a manifestation of the very nature of the Christian faith, an echo of God’s love, which does not change and cannot be betrayed. This article delves into the dimensions of this principle, not merely to describe it but to explore its scope, foundation, strength, and beauty.

I. THE VICENTIAN PRINCIPLE: NATURE AND DIMENSION

In his Commonitorium, St. Vincent of Lerins offers us a criterion for distinguishing true doctrine from heresies:

“True faith is that which has been believed everywhere, always, and by everyone.”

This principle has three fundamental dimensions, which are not merely descriptive but express the very nature of revealed Truth.

1. UNIVERSALITY (UBIQUE)

True faith must be accepted throughout the Church, without regional or cultural exceptions. This does not imply superficial uniformity but an essential unity in faith.

St. Thomas Aquinas reinforces this point by teaching that the truth of faith is catholica because it is not limited by space or time but belongs to the fullness of Christ’s Mystical Body:

“The Catholic faith is one because it is meant to unite all men in the same revealed Truth.”

2. ANTIQUITY (SEMPER)

True faith is not a recent invention or a reinterpretation of what has already been received; it is a continuous testimony from the Apostles. Antiquity is not measured merely in chronological terms but in its uninterrupted connection to apostolic Tradition.

St. Augustine expressed this clearly:

“That which is truly Catholic is not new, but what has always been believed from the beginning.”

3. CONSENSUS (AB OMNIBUS)

True faith is that which has been accepted by the entire body of the Church, not by an intellectual elite or an isolated group. This consensus reflects the sensus fidelium, the supernatural instinct of the faithful guided by the Holy Spirit.

St. Leo the Great strongly affirmed:

“What has been believed by God’s people from the beginning cannot be doubted, for in it resounds the voice of Christ who lives in His Church.”

II. THE SCOPE OF THE VICENTIAN PRINCIPLE

The Vicentian principle does not only have doctrinal application but encompasses the entire life of the Church: liturgy, morality, and spirituality.

1. IN DOCTRINE: AN INCORRUPT FAITH

The principle ensures that any legitimate doctrinal development must be consistent with what has been received. Blessed John Henry Newman stated:

“Authentic development does not alter the substance of the faith but unfolds and clarifies it. Any contradiction with the ancient is a sign of corruption.”

2. IN LITURGY: A FAITH THAT PRAYS

Liturgy is the visible expression of the faith. The Vicentian principle ensures that any liturgical reform must be in continuity with Tradition. St. Pius V declared when promulgating the Tridentine Mass:

“Nothing should be added to what has been transmitted to us, for what has been consecrated by Tradition needs no correction.”

3. IN MORALITY: AN ETERNAL LAW

Christian morality is not a flexible ethical system but an expression of Divine Law. St. Francis de Sales remarked:

“The love of God does not change, nor does His law. What was holy yesterday remains holy today and will be for all eternity.”

III. THE VICENTIAN PRINCIPLE AS A RESPONSE TO HERESIES

Throughout history, the Vicentian principle has been an essential criterion for refuting heresies and preserving the faith.

1. THE ARIAN CRISIS

St. Athanasius defended the consubstantiality of the Son with the Father by appealing to the Church’s consensus:

“We do not preach something new, but what the Church has always believed: that the Son is of the same essence as the Father.”

2. PELAGIANISM

St. Augustine refuted Pelagius by demonstrating that the doctrine of grace is part of the deposit of faith:

“Grace is not an addition but the foundation of our faith, received from Christ Himself.”

3. THE DIVINE MOTHERHOOD

At the Council of Ephesus, St. Cyril of Alexandria defended Mary as Theotokos, showing that this truth is rooted in Tradition:

“What we say of Mary, we say of Christ, for she is the Mother of the Incarnate Word.”

IV. THE VICENTIAN PRINCIPLE IN THE RELATIONSHIP BETWEEN LEX ORANDI AND LEX CREDENDI

The Catholic faith is not only professed in words but lived and expressed through liturgical prayer. This inseparable link between lex orandi (the law of prayer) and lex credendi (the law of faith) is a direct manifestation of the Vicentian principle: what has always been believed has always been prayed. The liturgy is a living testimony to the continuity of faith.

1. LITURGY AS AN EXPRESSION OF TRUTH

St. Vincent of Lerins does not only refer to doctrine in its conceptual form but also to its expression in the Church’s life. Liturgy, as the highest public act of worship to God, reflects and guards the deposit of faith.

2. LEX ORANDI, LEX CREDENDI: A VITAL RELATIONSHIP

The principle lex orandi, lex credendi affirms that how we pray reflects and forms our faith. If the Church’s prayer deviates from Tradition, the faith itself can be endangered.

3. LITURGY AS A TESTIMONY OF TRADITION

Continuity in liturgy ensures that the faith remains rooted in its apostolic source. Radical changes in liturgical expressions can obscure essential truths. Dom Prosper Guéranger noted:

“The liturgy is living Tradition because it radiates what the Church has always believed.”

V. CONCLUSION: A CALL TO SUPREME FAITHFULNESS

The Vicentian principle is not just a theological norm; it is a hymn to eternal Truth, a tribute to the fidelity of Christ, who promised that the gates of hell would not prevail against His Church.

St. Vincent expressed it masterfully:

“True faith does not need novelty, for in it shines the light of eternity.”

This principle challenges us to be guardians of Truth with clear minds and burning hearts, trusting that by remaining faithful to what has always been believed, we walk toward the God who never changes.
