The Bible does not teach that it is the sole authority

Before I proceed to the rebuttals, I have to repeat what I had said in my conclusion: "I do believe that Christian life is not just centered on the Bible..." It would mean that Christianity is not all about the Bible in the sense that we must depend on the Bible always. But, again, as said, "...but it is the only authority and guide for Christians" I have added the word "guide" since in reality, the Bible guides us. Without the Bible, how can we know about God? One common argument from non Sola Scriptura denomination is that, "how come Jesus and the Apostles did not use the Bible in teaching others?" To answer that, Jesus and the Apostles had used the Old Testament, and the Apostle Paul used his books (depending on the place. For example, he used Romans to address it to Rome), then, the Old Testament. Whatever Jesus and the Apostles had taught is clearly in the Bible. Let us just be glad to have one. It is difficult for the Apostles to teach without it, but now, for us, it is easy since we have that book. Rebuttal: 1) 2 Timothy 3:16-17 does not directly say that it is the only authority, but, as said in Proverbs 30:5-6, we should not add words to the Bible. 2) "Do not go beyond what is written" is not limited to Apollo, Cephas, and to himself, and to Corinthians as well. A lot of people who go beyond what is written had practiced unbiblical practices and traditions, focused more on preachers rather than the Bible, and everything. I do not want to go through these unbiblical practices since I may go out of topic. 3) "This says that every word of God is flawless, which I would suppose includes words outside of the Bible." The Word of God is the Bible alone. Though, you can create your own philosophies that is biblically based, that doesn't mean, it is the Word of God already. If we consider that the words outside the Bible is the "Word of God", too, then, people may tend to go literally outside the Bible like making own doctrines. 1 Thessalonians 2:13 is part of the Bible itself. It does not mean it is not from the Bible. As known, 1 Thessalonians is part of the New Testament. As said, in the early times, the Apostles does not have the Bible, but in the end, we are blessed to have one. What the Apostles taught is also in the Bible. Go to add one argument before conclusion: "Sola Scriptura" means "Bible alone", every authority of the church should follow it. It does not remove church authorities, but it tells and reminds us that the Bible is our GUIDE, that even church authorities and leaders should follow it, that when we go beyond it, there's a danger. Second, the Bible is a spiritual guide. Some would ask, "Do the Bible deals with morality like stem cell researches and abortion?" I just reply, "The Bible is a spiritual Christian guide." Though it may not directly deal with abortion issues and other morality issues, the Bible is teaching us spiritual relationship with God wherein morality will follow. Conclusion: "Sola Scriptura" does not take away the authorities of church leaders, but, it only gives high regard for the Bible as the "only" authority. "Only" means, "do not go beyond what is written". Take note: Scripture alone does NOT take away church authorities, but it is the HIGHEST authority, and NO authority can be higher than it. "Heaven and earth will pass away, but my words will never pass away." - Matthew 24:35
