A common question arises: if everything must be in the Bible, then what is the purpose of Holy Tradition? Conversely, if there is tradition, does that mean the Bible is lacking? The Catechism (§80-87, §97-100) clearly states: Tradition and Scripture are closely linked; together they form “one temple of the Word of God” in which the Church both listens to and lives the revelation. St. Paul also invites the faithful to hold fast to what has been handed down, whether by word of mouth or by letter (referencing 2 Thess 2:15 in the teaching on apostolic tradition).
Tradition is not “arbitrary custom”
Holy Tradition is the apostolic tradition under the guidance of the Holy Spirit in the Church: liturgy, living catechesis, and Scripture are received and understood. It is not identical to local customs or personal habits. When someone says “according to tradition” without being able to point to communion with apostolic faith, caution is needed.
The Bible remains supreme in text
This does not diminish the authority of Scripture: the Bible is The Word of God written down, norma normans. Tradition preserves and transmits the entirety of revelation; the Magisterium serves both. Further insights can be found in who wrote the Bible and faith and good works to see the unified thread of salvation.
Official sources instead of rumors
This article does not replace pastoral teaching or the full Catechism. When verifying, please refer to the Compendium of the Catechism and the texts of Vatican II — especially Dei Verbum with questions about Scripture. Websites claiming to be “Catholic teaching” without verifiable sources are insufficient as a basis for faith or morals. We do not endorse false citations or unverified “sacred sayings”; references here point to publicly published documents. If there is a discrepancy with the current Catechism, the text of the Catechism takes precedence.
In summary
- Scripture and Tradition both stem from revelation, inseparably linked.
- Tradition = apostolic in the Church, not arbitrary customs.
- Scripture is the recorded Word; the Magisterium serves to ensure correct understanding.
