Each person brings to the study and reception of the Revealed Word of God the filters of personal experience, culture, and language. The meanings of words change over time. A document as brief and recent as the Constitution is constantly under attack by those who would revise it by changing the meaning of the words used. Even parables change over time. How then did God ensure that the message of his Revealed Word was to remain timeless?
God is the architect of human nature and understands it perfectly. Pride, individualism, vanity, prejudice, and even hatred influence how we interpret the Revealed Word. To counter balance these influences and to maintain the fidelity of His Word God implemented a trinity of Revelation; Sacred Scripture, Apostolic Tradition, and the Magisterium. They represent the harmony and completeness of the Word. All three are required to preserve and convey the message, individually they are flawed and subject to intentional and unintentional perversion by human nature. Doctrines based on only one of the three are an amplification of the limitations of each.
So would you then say the ecclesiastical leadership is immune to personal experiences,culture and language? Do they not bring their own doctrinal and personal prejustice with them ?
When reading "the church Fathers" we see differing interpretations of scripture..do you suppose it is not still true today?
