In this special episode of the Eucharist Podcast, Fr. John Trammell leads a discussion about St. Vincent of Lérins, his life and his most famous contribution to the ancient church -- the Vincentian Canon.

How can individuals discern Christian truth from heretical falsehood? How does one avoid falling into heresy? And how can doctrine develop over time while avoiding disintegration of the faith once delivered to the saints? These are the questions St. Vincent of Lérins set about answering in 434 AD in his revered work, The Commonitory.
