But there is. It is in John 6. And tradition is extremely important in the church, which is where we get the connection from through John 6 and our Early church fathers, who were there not long at all after Christ; St. Ignatius of Antioch (110 AD),
St. Justin Martyr (155 AD), St Irenaeus of Lyons (180 AD). But Mark, see, sola scriptura doesn't make sense, and here's why. A christian who believes that the Bible is the sole rule of faith believes that all questions relating to faith and morals can be answered completely from the written word of God as contained in all the books from Genisis to Revelation. That being the case, there is no need for any other rule to guide the christian, whether it be tradition, a teaching authority, philosophy, or nature. These inhibit a Christian's path to salvation.
However! A bible only approach, when applied logically, runs into immediate and numerous problems. For example, can a Bible held in the hand of any Christian answer the following questions: "How do I know that my bible was correctly translated?;" " Does my bible have the correct number of books in both the old and the new testament?;" "Is the interpretation of this or that verse the correct one?;" Ordinary Christians lacking an extensive knowledge of the languages, cultures and history of the Holy Land and its surrounds would be hard pressed to answer with certainty any of these questions, with or without a Bible!
Does the Bible teach that it is the sole rule of faith, Mark?
