ISB ~ 2 Timothy 3 v17

complete:Paul extols Scripture as a preeminent guide for the moral life. He does not claim, however, that Scripture supplies us with comprehensive instruction in all matters of Christian doctrine, worship, and ecclesial government. Besides the divine authority of the biblical books, he also acknowledges the authority of apostolic tradition (1 Cor 11:1; 2 Thess 2:15) and sees the Church, built on the foundation of Christ and the apostles (1 Cor 3:11; Eph 2:20), as the bearer of God’s truth to the world (1 Tim 3:15). For the role of tradition and the teaching office of the Magisterium, see notes on Jn 14:26, 16:13, and 2 Thess 2:15.

• Sacred Scripture is extremely profitable for the soul. Like a tree planted near a stream, the soul that is watered by Scripture grows hearty and bears fruit in due season. It is fitted with leaves that are always green, with actions pleasing to God (St. John of Damascus, Orthodox Faith 4, 17).
