Tradition is the process of maintaining religious faith and integrity by passing down religious knowledge and God’s truth to future generations (Sirach 50:27, Psalm 119:130). This practice is theologically significant as it provides authoritative spiritual guidance.

The New Testament demonstrates that the written Word is supported by oral and eyewitness traditions. For instance, the Gospel of Mark was compiled using various oral and written sources, while the Gospel of Luke relies on eyewitness traditions to convey the message of Jesus Christ (Luke 1:2-4). This continuity between the ministry of Jesus and that of the apostles guarantees that the Church’s teaching remains faithful to the original teachings of Jesus (Luke 1:4; Acts 10:37-42).

Apostolic tradition serves as a safeguard for the faith, providing a developed ecclesiastical structure for the transmission of doctrine. The Letter of Jude emphasizes the importance of the tradition and doctrine handed down by the apostles (Jude 1:3), and the Second Letter of Peter appeals to both tradition and scripture to counteract false teachings (2 Peter 3:14-16). Similarly, the community in Thessalonica is encouraged to hold fast to traditions passed down by the apostles, so as to remain steadfast against deception (2 Thessalonians 2:1-12).

The preservation of the faith relies on the proclamation of the word and the adherence to sound doctrine. In the letter to Timothy, Paul stresses the necessity of relying on the power of scripture alongside the proclamation of the word and sound doctrine to stand firm in one’s convictions (2 Timothy 3:14-4:2). This theological framework is essential for protecting the Christian community from the devastating impact of false teaching.
