Scripture and Apostolic Tradition
One apostolic deposit handed on in Sacred Scripture and the living Apostolic Tradition of the Church.
Sacred Scripture and Sacred Tradition transmit the one Word of God entrusted to the apostles. The Magisterium is not a third source of revelation and does not stand above God’s Word; it serves the deposit by authentically interpreting and guarding it.
Apostolic Tradition, not every custom: Sacred Scripture and Sacred Tradition hand on the one deposit of faith. See Dei Verbum 9–10.

Make the case
Define the Catholic claim accurately, state the strongest fair objection, and use the evidence without shortcuts.
The actual Catholic claim
Sacred Scripture and Sacred Tradition transmit the one Word of God entrusted to the apostles. The Magisterium is not a third source of revelation and does not stand above God’s Word; it serves the deposit by authentically interpreting and guarding it.
The interpretive guardrail
Not every custom or historical habit is Sacred Tradition. Apostolic Tradition concerns the Gospel handed on in the Church’s faith, worship, teaching, and life.
Read the key passages in context
Open each passage for its setting, Douay-Rheims text, contribution to the case, and proper limit.
2 Thessalonians 2:14–15 (Douay-Rheims numbering) — Primary text
Read in context: Read 2 Thessalonians 2:13–16 in the Douay-Rheims; verse numbering differs in some modern editions, where “stand fast” is commonly numbered 2:15.
Therefore, brethren, stand fast; and hold the traditions which you have learned, whether by word, or by our epistle.
Paul commands Christians to hold apostolic teaching received in both oral and written forms.
The verse does not validate every later human practice; the tradition in view is authoritative apostolic teaching.
Acts 2:42 — Primary text
Read in context: Read Acts 2:37–47: Baptism leads into a visible community persevering in apostolic doctrine, communion, Eucharistic breaking of bread, and prayer.
They were persevering in the doctrine of the apostles, and in the communication of the breaking of bread, and in prayers.
The earliest Church lives by an integrated apostolic pattern of doctrine, sacramental communion, and worship.
The passage does not reduce apostolic doctrine to unwritten material; it shows the ecclesial setting in which the New Testament itself emerges.
2 Timothy 2:2 — Primary text
Read in context: Read 2 Timothy 1:13–2:7: Paul commands Timothy to guard a received pattern and entrust it to reliable teachers.
The things which thou hast heard of me by many witnesses, the same commend to faithful men, who shall be fit to teach others also.
Apostolic teaching is transmitted through successive, accountable teachers rather than through isolated private discovery.
This succession serves the Gospel; it does not authorize later teachers to invent a different revelation.
The wider biblical witness
Place the primary texts inside the whole economy of salvation.
Biblical connection
1 Corinthians 11:2 — received ordinances
Biblical connection
1 Thessalonians 2:13 — receiving the apostolic word as God’s word
Biblical connection
John 20:30 and 21:25 — not everything Jesus did is contained in the Gospel narrative
Biblical connection
2 Peter 3:15–17 — inspired writings can be distorted
Biblical connection
Acts 15:1–29 — the Church resolves a doctrinal controversy
Objection and Catholic response
Answer the strongest fair objection without caricature or rhetorical shortcuts.
The objection
Jesus condemned tradition, and 2 Timothy 3:16 says Scripture is sufficient; therefore all binding Christian teaching must be written in the Bible.
The Catholic response
Jesus condemns traditions that nullify God’s command, not all authoritative handing-on. Paul both exalts inspired Scripture and commands Christians to hold apostolic traditions delivered orally and in writing. Catholic teaching does not diminish Scripture; it rejects separating Scripture from the apostolic Church that received, canonized, proclaimed, and interpreted it.
Use it in conversation
Move from a precise claim to a necessary distinction and then to the strongest evidence.
Scripture and Tradition transmit one apostolic deposit.
Apostolic Tradition is not every custom, and the Magisterium is not a third revelation.
Use 2 Thessalonians 2, Acts 2, 2 Timothy 2, and Dei Verbum.
Verify the teaching
