All false doctrine comes from those who are not led by the Spirit either in the original understanding or the interpretation.
Exactly. Anyway, edification is still always possible, for those with ears to hear:
80 "Sacred Tradition and Sacred Scripture, then, are bound closely together, and communicate one with the other. For both of them, flowing out from the same divine well-spring, come together in some fashion to form one thing, and move towards the same goal."40 Each of them makes present and fruitful in the Church the mystery of Christ, who promised to remain with his own "always, to the close of the age".41
. . . two distinct modes of transmission
81 "
Sacred Scripture is the speech of God as it is put down in writing under the breath of the Holy Spirit."42
"And [Holy]
Tradition transmits in its entirety the Word of God which has been entrusted to the apostles by Christ the Lord and the Holy Spirit. It transmits it to the successors of the apostles so that, enlightened by the Spirit of truth, they may faithfully preserve, expound and spread it abroad by their preaching."43
82 As a result the Church, to whom the transmission and interpretation of Revelation is entrusted, "does not derive her certainty about all revealed truths from the holy Scriptures alone. Both Scripture and Tradition must be accepted and honored with equal sentiments of devotion and reverence."44
85 "The task of giving an authentic interpretation of the Word of God, whether in its written form or in the form of Tradition, has been entrusted to the living teaching office of the Church alone. Its authority in this matter is exercised in the name of Jesus Christ."47 This means that the task of interpretation has been entrusted to the bishops in communion with the successor of Peter, the Bishop of Rome.
86 "Yet this Magisterium is not superior to the Word of God, but is its servant. It teaches only what has been handed on to it. At the divine command and with the help of the Holy Spirit, it listens to this devotedly, guards it with dedication and expounds it faithfully. All that it proposes for belief as being divinely revealed is drawn from this single deposit of faith."48
104 In Sacred Scripture, the Church constantly finds her nourishment and her strength, for she welcomes it not as a human word, "but as what it really is, the word of God".67 "In the sacred books, the Father who is in heaven comes lovingly to meet his children, and talks with them."68
II. INSPIRATION AND TRUTH OF SACRED SCRIPTURE
105 God is the author of Sacred Scripture. "The divinely revealed realities, which are contained and presented in the text of Sacred Scripture, have been written down under the inspiration of the Holy Spirit."69
"For Holy Mother Church, relying on the faith of the apostolic age, accepts as sacred and canonical the books of the Old and the New Testaments, whole and entire, with all their parts, on the grounds that, written under the inspiration of the Holy Spirit, they have God as their author, and have been handed on as such to the Church herself."70
106 God inspired the human authors of the sacred books. "To compose the sacred books, God chose certain men who, all the while he employed them in this task, made full use of their own faculties and powers so that, though he acted in them and by them, it was as true authors that they consigned to writing whatever he wanted written, and no more."71
107 The inspired books teach the truth. "Since therefore all that the inspired authors or sacred writers affirm should be regarded as affirmed by the Holy Spirit, we must acknowledge that the books of Scripture firmly, faithfully, and without error teach that truth which God, for the sake of our salvation, wished to see confided to the Sacred Scriptures."72
108 Still, the Christian faith is not a "religion of the book." Christianity is the religion of the "Word" of God, a word which is "not a written and mute word, but the Word which is incarnate and living".73 If the Scriptures are not to remain a dead letter, Christ, the eternal Word of the living God, must, through the Holy Spirit, "open [our] minds to understand the Scriptures."74
III. THE HOLY SPIRIT, INTERPRETER OF SCRIPTURE
109 In Sacred Scripture, God speaks to man in a human way. To interpret Scripture correctly, the reader must be attentive to what the human authors truly wanted to affirm, and to what God wanted to reveal to us by their words.75
110 In order to discover
the sacred authors' intention, the reader must take into account the conditions of their time and culture, the literary genres in use at that time, and the modes of feeling, speaking and narrating then current. "For the fact is that truth is differently presented and expressed in the various types of historical writing, in prophetical and poetical texts, and in other forms of literary expression."76
111 But since Sacred Scripture is inspired, there is another and no less important principle of correct interpretation, without which Scripture would remain a dead letter. "Sacred Scripture must be read and interpreted in the light of the same Spirit by whom it was written."77
The Second Vatican Council indicates three criteria for interpreting Scripture in accordance with the Spirit who inspired it.78
112 1.
Be especially attentive "to the content and unity of the whole Scripture". Different as the books which compose it may be, Scripture is a unity by reason of the unity of God's plan, of which Christ Jesus is the center and heart, open since his Passover.79
The phrase "heart of Christ" can refer to Sacred Scripture, which makes known his heart, closed before the Passion, as the Scripture was obscure. But the Scripture has been opened since the Passion; since those who from then on have understood it, consider and discern in what way the prophecies must be interpreted.80
113 2.
Read the Scripture within "the living Tradition of the whole Church". According to a saying of the Fathers, Sacred Scripture is written principally in the Church's heart rather than in documents and records, for the Church carries in her Tradition the living memorial of God's Word, and it is the Holy Spirit who gives her the spiritual interpretation of the Scripture (". . . according to the spiritual meaning which the Spirit grants to the Church"81).
114 3.
Be attentive to the analogy of faith.82 By "analogy of faith" we mean the coherence of the truths of faith among themselves and within the whole plan of Revelation.
