The Short Answer

The New Testament does not merely permit Sacred Tradition — it commands it. Paul explicitly places oral Tradition on equal footing with written Scripture, instructs his communities to guard and transmit what they received, and himself transmits creedal and liturgical formulas that were circulating in the Church before his letters were written. Anyone who reads Paul carefully and honestly must reckon with a Christianity that was always more than a book — it was a living deposit of faith, transmitted through persons, communities, and the apostolic succession of teaching authority.

Paul Commands Tradition

The key text is 2 Thessalonians 2:15. Paul does not write “hold fast to the letters we send you.” He writes “hold fast to the traditions” — and he explicitly names two channels: word of mouth and letter. The oral channel — word of mouth — is not subordinate to the written channel. Both are authoritative; both must be held. Paul places them side by side without hierarchy.

The Greek word Paul uses is paradoseis — traditions, from paradidomi, to hand on, to transmit. This is the same word used in 1 Corinthians 11:2, where Paul commends the Corinthians “because you remember me in everything and maintain the traditions even as I delivered them to you.” And in 1 Corinthians 15:3, where Paul writes: “For I delivered to you as of first importance what I also received.” The vocabulary of handing on, receiving, and maintaining is the vocabulary of Tradition — a structured, authoritative transmission of a defined deposit.

This is not incidental. For Paul, the faith is something that exists prior to any individual believer and is received through a process of transmission. You do not construct it from the text. You receive it from those who received it from the apostles.

Pre-Pauline Formulas in Paul’s Letters

Scholars across the theological spectrum — Catholic, Protestant, and secular — recognize that Paul’s letters contain embedded creedal and hymnic formulas that predate the letters themselves. These are fragments of oral Tradition that Paul quotes, indicating that the early Church had a structured doctrinal deposit before a single word of the New Testament was written.

The most famous example is Philippians 2:6–11 — the “Christ Hymn.” Its poetic structure, its vocabulary (several words appear nowhere else in Paul’s letters), and its self-contained theological statement all indicate that Paul is quoting a hymn already in circulation. Similarly, 1 Timothy 3:16 (“He was manifested in the flesh, vindicated by the Spirit, seen by angels…”) has the character of a liturgical formula. Romans 1:3–4 appears to be another pre-Pauline creedal statement about Christ’s Davidic descent and resurrection.

These fragments reveal something important: the deposit of faith was not created by the New Testament writings. The writings themselves drew on a prior oral deposit — Tradition — that was already shaping the Church’s worship, catechesis, and proclamation before any apostolic letter was completed and sent.

The Eucharistic Tradition

In 1 Corinthians 11:23–26, Paul introduces his account of the Last Supper with the formula of Tradition: “For I received from the Lord what I also passed on to you.” He received the Eucharistic teaching and he passed it on — parelabon and paredoka, the verbs of receiving and handing on.

This is striking because Paul’s account of the Last Supper predates the written Gospels. Mark’s Gospel, the earliest, was likely not written until the 60s AD. Paul’s first letter to the Corinthians was written around 54–55 AD. The Eucharistic tradition Paul transmits in 1 Corinthians 11 was therefore circulating orally in the Church — kept alive through liturgical practice and apostolic teaching — for twenty years before it appeared in written form.

This is Sacred Tradition in action: the Church preserving and transmitting the words and actions of Christ through living practice, prior to and independent of written Scripture.

The Church as Pillar of Truth

In 1 Timothy 3:15, Paul identifies the guardian of the deposit of faith. He does not say “the Scripture is the pillar and bulwark of truth.” He says the Church is: “the household of God, which is the church of the living God, the pillar and bulwark of the truth.” The Church — a person, a community, an institution with structure and authority — is named as the bearer and defender of truth.

This is not a marginal text. It is Paul’s description of why he is writing the pastoral letters at all: to instruct Timothy on how to order the household of God that is entrusted with the truth. The truth lives in the Church. The Church is not a mere custodian of a text that stands over it. The Church and its apostolic teaching — its Tradition — is the living bearer of what Christ gave.

Timothy’s Commission

Second Timothy 2:2 provides a clear picture of how apostolic Tradition is meant to propagate: “And the things you have heard me say in the presence of many witnesses entrust to reliable people who will also be qualified to teach others.” Paul → Timothy → reliable teachers → others. This is a chain of transmission — apostolic succession in its most basic form — and it operates through persons, not through texts alone.

Timothy is not told to write everything down for future generations to read. He is told to entrust what he has received to people who can teach it. The primary mode of transmission is personal and communal. Written texts are a supplement to this chain, not its replacement.

What This Means for Us

The evidence Paul left us dismantles the idea that Christianity was ever a religion of the book alone. The New Testament was written within a community that already possessed the faith, already celebrated the sacraments, already knew the creeds, already had authority structures. Scripture is the written crystallization of a part of that deposit — indispensable, inspired, and normative — but not the whole of it and not self-interpreting.

When Catholics speak of Scripture and Tradition as two modes of a single deposit, they are not inventing a convenient loophole. They are describing what Paul actually practiced and commanded. To read Paul carefully is to encounter a man who thought of the faith as something received, guarded, transmitted, and lived — in communities, under authority, through a chain of witnesses stretching from the upper room to the present day.
