This why the Church/magisterium is so important-to discern the truth-to distinguish between symbolic and literal language, to glean and correctly understand the message within a particular passage. So the Catechism teaches:
390 The account of the fall in Genesis 3 uses figurative language, but affirms a primeval event, a deed that took place at the beginning of the history of man . Revelation gives us the certainty of faith that the whole of human history is marked by the original fault freely committed by our first parents.
Because that happens to be her job:
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.
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).
