You have confused me to the point of spinning.
Scripture is the final authority in this way, anything claimed to be Christian doctrine, must not contradict scripture.
Is this difficult?
Let me write it another way,
If a doctrine contradicts scripture, then it is false.
Lets make this an argument,
God preached the Good News to men. These men and their followers wrote down what God said. What is written down is called scripture. Therefore, to know what God has said, people read scripture. If someone says God said something, and this something contradicts what is in scripture, then God didn't say it.
Hello Sean, Let me give you just one example of many i can give
One of the dreadful consequences of division is lack of successful evangelism. Division depletes and diminishes our ability to reach the lost. In Jesus' prayer for unity, he asks:"I do not pray for these alone, but also for those who will believe in Me through their word; that they all may be one, as You, Father, are in Me, and I in You; that they also may be one in Us, that the world may believe that You sent Me." (John 17:20-21
Jesus prayed these words in the Upper Room on the night of his betrayal, knowing that crucifixion would follow with the coming sunrise. The words are part of his final words, and final words have a history of being intense, focused and passionate. So it was with Jesus. Never before had the disciples heard him pray like this.
That they may be one. For this he would sweat blood, endure mockery and freely lay down his life. To make this brief prayer efficacious, he would rise in Easter glory and in the power of the Holy Spirit be permanently in the world, gathering into "one" the whole people of God. One shepherd, as he had promised, and one flock would follow. The apostolic messengers would proclaim one Lord, one faith, one baptism, one God and Father of us all.
Protestant Bibical Historians give us an indication of how the Church has always operated in re guard to the Bible and Apostolic Tradition here.
Philip Schaff, a major Protestant church historian from last century writes in his History of the Christian Church --
"The church view respecting the sources of Christian theology and the rule of faith and practice remains as it was in the previous period, except that it is further developed in particulars. The divine Scriptures of the Old and New Testaments, as opposed to human writings; AND the ORAL TRADITION or LIVING FAITH of the catholic church from the apostles down, as opposed to the varying opinions of heretical sects -- TOGETHER FORM THE ONE INFALLIBLE SOURCE AND RULE OF FAITH. BOTH are vehicles of the same substance: the saving revelation of God in Christ; with this difference in form and office, that the church tradition determines the canon, furnishes the KEY TO THE TRUE INTERPRETATION of the Scriptures, and guards them against heretical abuse." (volume 3, page 606)
J.N.D. Kelly, a major Protestant church historian from this century writes in his Early Christian Doctrines -- (after many examples)
"It should be unnecessary to accumulate further evidence. Throughout the whole period Scripture AND tradition ranked as complementary authorities, media different in form but coincident in content. To inquire which counted as superior or more ultimate is to pose the question in misleading and anachronistic terms. If Scripture was abundantly sufficient in principle, tradition was recognized as the SUREST CLUE TO ITS INTERPRETATION, for in TRADITION the Church retained, as a legacy from the apostles which was embedded in all the organs of her institutional life, an UNERRING GRASP of the real purport and MEANING of the revelation to which Scripture AND tradition alike bore witness." (page 47-4
Thus in the end the Christian must, like Timothy [cf. 1 Tim 6:20] 'guard the deposit', i.e. the revelation enshrined in its completeness in Holy Scripture and CORRECTLY interpreted in the Church's UNERRING tradition." (page 51)
If you read early Christian History you will find that there were many heretical sects who claimed that they were correct in their Bible interpretation and like these historians tell us when this came up the SUREST CLUE TO ITS INTERPRETATION, is the TRADITION the Church retained, as a legacy from the apostles.
The Church operates the same way today and today we have the same problem as the early Church. Different Churches bring different interpretations to the Bible splitting the body of Christ into many pieces which is against what Jesus prayed for.
Now here is just one modern example of what happens when Apostolic legacy is lost.
