The Christian Conversation

This treatise emphasizes that the true and enduring Catholic faith is rooted in the antiquity, universality, and consent of the Church's tradition and sacred Scriptures, and that deviations or novelties threaten its integrity.

Vincent of Lérins advocates for diligent safeguarding of established doctrine through the authority of Holy Scripture, consistent interpretation aligned with the consensus of the Church Fathers, and rejection of innovations that contradict the historic faith upheld by ecumenical councils.

He illustrates these principles through historical examples of heresies and heretical figures, underscoring the importance of fidelity to the tradition of the Fathers and the necessity of opposing false teachings to preserve divine truth for future generations.
