Editing Sacred Tradition (section)

== Councils and Magisterial Affirmations ==
The continuity of Scripture and Tradition is a constant theme in the Church’s Councils:

* **[[Council of Ephesus]] (AD 431)** – defended the apostolic faith against Nestorian innovations by appealing to the unbroken teaching of the Fathers.
* **[[Council of Chalcedon]] (AD 451)** – defined Christ’s two natures “following the holy Fathers.”
* **[[Council of Trent]] (1545–1563)** – reaffirmed the equal authority of apostolic Tradition and Scripture against Protestant claims of ''sola Scriptura''.
* **[[Vatican I]] (1870), *Dei Filius*, ch. 2** –

> “This supernatural revelation, according to the universal belief of the Church, is contained in written books and unwritten traditions, which, received by the Apostles from the mouth of Christ Himself or by the Apostles from the dictation of the Holy Spirit, have come down even unto us.”

* **[[Second Vatican Council]] (1962–1965)** – *[[Dei Verbum]]* reaffirmed that both Scripture and Tradition “must be accepted and honored with equal feelings of devotion and reverence” (§9).
