But that’s my point!
Sacred Tradition is where we got the Bible from: the canon of the Scriptures was known to the Church from the Apostles, with the Church transmitting (handing on/down) these sacred resources from generation to generation. With the help and guidance of the Holy Spirit, the Church was able to discern authoritatively and certainly which books already in her possession from the Apostles were wholly inspired by the Holy Spirit as Public Revelation, and therefore also true Word of God, and which were secondary to it (e.g., Pope St. Clement’s Letters to the Corinthians that they, apparently, thought were inspired Word of God on the same level of authority as the letters of the Apotles, e.g.).
The Word of God is, first and foremost, a Person: i.e., not a “something” but a living “Someone”. Scripture and Tradition, then, are just the heads and tails of a singular coin that has its sacred value because its substance is something divine: i.e., the Word of God; and it is legal tender because it is stamped or sealed by that same authority (Apostolic tradition and the Magisterium).
Protestants and Catholics agree that the Word of God is the ultimate source of all authority and also an irreproachable authority: realizing that we are talking ultimately about a Someone and not a something will help a long way toward reconciliation and agreement.
