“In the catholic church itself... we hold that faith which has been believed everywhere, always, by all.” - Vincent of Lérins (3??-c. 445), Monk
A classic definition of catholicity was articulated by Vincent of Lérins, a 4th/5th century French monk. While Scripture was complete and sufficient in itself, different interpretations of Scripture could exist. When faced with conflicting interpretations, the church should evaluate them according to a basic rule, now called “The Vincentian Canon”: what “has been believed always, everywhere, by all”? Vincent pointed to an example - the A***n teaching gained traction for a time among Western bishops, but it was rejected because it conflicted with Scripture and with the majority of Biblical interpretations of the early church. “All novelty in faith is a sure mark of heresy,” Vincent noted. Yet Vincent didn’t necessarily equate change with novelty. He was not opposed to progress in Christian doctrine, but progress could never be contrary to the standard set by the consensus of earlier generations. As times change and ministerial realities develop, the church must always look to Scripture and the consensus of the historic church’s interpretation of Scripture as the guardrails of orthodoxy. Vincent’s logic has been echoed through the centuries by writers like G.K. Chesterton, who reminded us to consult the “democracy of the dead” and C.S. Lewis who said to “keep the clean, sea breeze of the centuries blowing through our minds” as we evaluate modern interpretations and applications of Scripture.
O God, who by your Holy Spirit moved Vincent of Lérins to manifest to your church the way of perfection: Grant us, we pray, to be nourished by his teaching, and enkindle within us a keen and unquenchable longing for true holiness; through Jesus Christ, the joy of loving hearts, who with you and the Holy Spirit lives and reigns, one God, for ever and ever. Amen.
