What Is Sacred Tradition, and Is It Biblical?

October 18, 2026

"Catholics follow the traditions of men, and Jesus condemned that." Jesus really did condemn a kind of tradition. The question is which kind.

Short answer: Sacred Tradition is the teaching of Jesus and the apostles handed on in the Church by preaching and practice, not only in writing. It is biblical: St. Paul commands Christians to "hold fast to the traditions that you were taught, either by an oral statement or by a letter of ours" (2 Thessalonians 2:15). What Jesus condemned was human tradition that nullifies God's word (Mark 7:8–13).

Key verses on Sacred Tradition

"hold fast to the traditions that you were taught, either by an oral statement or by a letter of ours" (2 Thessalonians 2:15)
"hold fast to the traditions, just as I handed them on to you" (1 Corinthians 11:2)
"what you heard from me through many witnesses entrust to faithful people" (2 Timothy 2:2)
"you received not a human word but, as it truly is, the word of God" (1 Thessalonians 2:13)
"You disregard God’s commandment but cling to human tradition." (Mark 7:8)

What Catholics Actually Teach

God "graciously arranged that the things he had once revealed for the salvation of all peoples should remain in their entirety, throughout the ages, and be transmitted to all generations" (CCC 74).

The apostles handed on the Gospel in writing and also "by the spoken word of their preaching, by the example they gave, by the institutions they established" (CCC 76). "This living transmission, accomplished in the Holy Spirit, is called Tradition" (CCC 78).

Scripture and Tradition are not rivals. "Sacred Tradition and Sacred Scripture, then, are bound closely together, and communicate one with the other," because both flow "from the same divine well-spring" (CCC 80).

What Catholics do not teach:

That Tradition is a second, secret revelation. The Church teaches nothing as revealed that is not drawn from "this single deposit of faith" (CCC 86), the faith "once for all handed down to the holy ones" (Jude 3).
That every Catholic custom is Sacred Tradition. The Catechism distinguishes apostolic Tradition from "the various theological, disciplinary, liturgical or devotional traditions, born in the local churches over time." Those smaller traditions "can be retained, modified or even abandoned under the guidance of the Church's Magisterium" (CCC 83).
That the Church can override Scripture. The Magisterium "is not superior to the Word of God, but is its servant" (CCC 86).

It all points to Christ. Sacred Tradition is not a second source beside Jesus; it is Jesus, handed on. St. Paul describes it that way: "For I received from the Lord what I also handed on to you" (1 Corinthians 11:23). Scripture and Tradition flow from Christ and lead back to Christ; the Church only guards and passes on what He gave.

The Biblical Case

1. St. Paul uses "tradition" as a command, not a warning

"Therefore, brothers, stand firm and hold fast to the traditions that you were taught, either by an oral statement or by a letter of ours." (2 Thessalonians 2:15)

Spoken and written teaching carry equal weight. St. Paul later tells them to shun anyone who lives "not according to the tradition they received from us" (2 Thessalonians 3:6). And he praises the Corinthians because they "hold fast to the traditions, just as I handed them on to you" (1 Corinthians 11:2).

2. The Gospel was preached before it was written

Of his preaching St. Paul wrote, "you received not a human word but, as it truly is, the word of God" (1 Thessalonians 2:13). St. Luke wrote his Gospel from what "eyewitnesses from the beginning and ministers of the word have handed them down to us" (Luke 1:2). Even St. Paul's account of the Last Supper came first as tradition: "For I received from the Lord what I also handed on to you" (1 Corinthians 11:23).

3. Tradition was meant to outlive the apostles

"And what you heard from me through many witnesses entrust to faithful people who will have the ability to teach others as well." (2 Timothy 2:2)

Four generations, linked by what was heard. St. Paul also tells St. Timothy, "Take as your norm the sound words that you heard from me," and "Guard this rich trust with the help of the holy Spirit that dwells within us" (2 Timothy 1:13–14).

4. Christ promised His Spirit would guard the truth

Jesus told the apostles, "I have much more to tell you, but you cannot bear it now. But when he comes, the Spirit of truth, he will guide you to all truth" (John 16:12–13). St. Paul calls the Church "the pillar and foundation of truth" (1 Timothy 3:15). Tradition is not the Church inventing doctrine; it is Christ protecting what He handed on.

5. Scripture never claims to contain everything

"There are also many other things that Jesus did, but if these were to be described individually, I do not think the whole world would contain the books that would be written" (John 21:25). That proves no particular unwritten teaching, but Scripture never claims to be exhaustive. And the list of which books belong in the Bible is found in no verse. "It was by the apostolic Tradition that the Church discerned which writings are to be included in the list of the sacred books" (CCC 120).

Objections Answered

(a) "Jesus condemned tradition."

At its strongest: Jesus told the Pharisees, "You disregard God’s commandment but cling to human tradition," and "You nullify the word of God in favor of your tradition that you have handed on" (Mark 7:8, 13). Catholicism is full of traditions. Isn't this what Jesus warned against?

Answer: Read Jesus' example. God commanded, "Honor your father and your mother," but the Pharisees let a man declare his support "qorban" (dedicated to God), and then "you allow him to do nothing more for his father or mother" (Mark 7:10–12). Jesus condemned human tradition that cancels God's command. St. Paul commands apostolic tradition that is itself "the word of God" (1 Thessalonians 2:13). The real question is not "tradition or no tradition?" but "from men, or from Christ through His apostles?"

(b) "Paul warned against human tradition too."

At its strongest: "See to it that no one captivate you with an empty, seductive philosophy according to human tradition, according to the elemental powers of the world and not according to Christ" (Colossians 2:8).

Answer: Notice St. Paul's qualifiers: "human tradition," "not according to Christ." Just before this, he tells the same readers to remain "established in the faith as you were taught" (Colossians 2:7). The Catholic Church makes the same distinction.

(c) "Tradition is a blank check. Anything can be called Tradition."

At its strongest: Written texts can be checked. Unwritten claims can't. Without Scripture alone as the test, what stops a church from claiming anything?

Answer: Scripture itself sets the limit. St. Paul bound his churches to what they had already received: "But even if we or an angel from heaven should preach [to you] a gospel other than the one that we preached to you, let that one be accursed!" (Galatians 1:8). The deposit is fixed, handed down "once for all" (Jude 3). Apostolic Tradition is not a blank check; it is a closed deposit. Sacred Tradition "comes from the apostles and hands on what they received from Jesus' teaching" (CCC 83). It never contradicts Scripture, since both come from one source (CCC 80), and the Magisterium serves the deposit of faith rather than adding to it (CCC 86). Early Christians also tested claims by what has been believed "everywhere, always, by all" (St. Vincent of Lérins, below). And every Christian reads the Bible within some tradition. The question is whether it is the apostles' tradition.

(d) "Scripture forbids adding to God's word."

At its strongest: Moses commanded, "you shall not add to what I command you nor subtract from it" (Deuteronomy 4:2), and Revelation warns, "if anyone adds to them, God will add to him the plagues described in this book" (Revelation 22:18). Accepting Tradition alongside Scripture looks like adding to God's word.

Answer: Read both verses in context. After Deuteronomy 4:2, God went on to speak through the Prophets, and later through Christ and His apostles. So the verse forbids men adding their own words to God's, not God speaking further. Revelation 22:18 guards "the prophetic words in this book," that is, Revelation itself. Sacred Tradition adds no new revelation; the Church teaches as revealed only what is drawn from "this single deposit of faith" (CCC 86). And St. Paul, writing under inspiration, commanded the oral traditions (2 Thessalonians 2:15). Holding them is not adding to God's word. It is obeying it.

The Early Church Agrees

Pope St. Clement I (St. Clement of Rome) (Letter to the Corinthians, c. AD 96, approximate) traces the chain of handing on: "The apostles have preached the gospel to us from the Lord Jesus Christ; Jesus Christ [has done so] from God." The apostles then "appointed the first fruits [of their labours], having first proved them by the Spirit, to be bishops and deacons of those who should afterwards believe" (ch. 42).
St. Irenaeus of Lyons (Against Heresies, c. AD 180): "the Church, having received this preaching and this faith, although scattered throughout the whole world, yet, as if occupying but one house, carefully preserves it." For "although the languages of the world are dissimilar, yet the import of the tradition is one and the same" (1.10.2). He even describes "those barbarians who believe in Christ" who have "salvation written in their hearts by the Spirit, without paper or ink, and, carefully preserving the ancient tradition," believe in one God, the Creator (3.4.2).
St. Basil the Great (On the Holy Spirit, c. AD 375, approximate): "Of the beliefs and practices whether generally accepted or publicly enjoined which are preserved in the Church some we possess derived from written teaching; others we have received delivered to us ‘in a mystery’ by the tradition of the apostles; and both of these in relation to true religion have the same force." His first example: the custom "to sign with the sign of the cross those who have trusted in the name of our Lord Jesus Christ" (27.66).
St. John Chrysostom (Homily 4 on 2 Thessalonians, c. AD 400, approximate), commenting on 2 Thessalonians 2:15: "Hence it is manifest, that they did not deliver all things by Epistle, but many things also unwritten, and in like manner both the one and the other are worthy of credit. Therefore let us think the tradition of the Church also worthy of credit. It is a tradition, seek no farther." (Homily 4)
St. Vincent of Lérins (Commonitory, c. AD 434): "Moreover, in the Catholic Church itself, all possible care must be taken, that we hold that faith which has been believed everywhere, always, by all." (2.6)

Conclusion

Sacred Tradition is not man-made customs stacked on the Bible. It is the apostles' own teaching, handed on by word and by letter, guarded by the Spirit in the Church Christ built. Scripture itself commands it. (See also Is Sola Scriptura in the Bible?)

If you are Protestant, you already honor the written part of the apostles' inheritance. Take 2 Thessalonians 2:15 at face value, and ask where the rest of what St. Paul handed on went.

Come home. The apostles' teaching, handed on by word and by letter, is still guarded whole in the Catholic Church. Christ did not found many churches. He founded one, on St. Peter and the apostles (Matthew 16:18), and that Church is the Catholic Church. "It is through Christ's Catholic Church alone, which is the universal help toward salvation, that the fullness of the means of salvation can be obtained" (CCC 816). If you are a baptized Christian, you already share "a certain, although imperfect, communion" with her (CCC 838). Every truth you already hold is a call to the rest of the way. Christ is calling you into the Catholic Church.

FAQ

Is Sacred Tradition the same as church customs? No. Particular devotions and disciplines are small-t traditions the Church can change. Sacred Tradition comes from the apostles (CCC 83).

Does Tradition add new doctrines to the Bible? No. Everything the Church teaches as revealed comes from one "single deposit of faith" (CCC 86).

Can you give an example of Sacred Tradition? The canon of Scripture. No verse lists the books of the Bible. The Church discerned that list "by the apostolic Tradition" (CCC 120).
