I am a non-denominational Trinitarian Christian who believes in the teaching of Sola Scriptura but I do not agree with the name "Sola Scriptura" because we need GOD to understand the Bible and not our own human mind, and wisdom alone. We need to ask God for help in our understanding of Scripture. GOD will not talk audibly to help us understand His Word, but He will guide us by His Spirit to compare Scripture with Scripture and He will bring to your mind those verses that you already know or have memorized to teach you.
I disagree also with Catholicism because they add things that we do not see into the Bible (like praying to Mary, the saints, confessing sins to a priest, bowing down to statues or kissing them, etc.). I believe Protestants also add things to the Bible, as well. While Protestants get some things right (like the Trinity, and the Bible being the only physical words of God that we are to follow), they also get other things wrong. For they believe in certain things that I believe are unbiblical (like: Eternal Security, or some level of a sin and still be saved type belief, support of Martin Luther, Grace Alone, 10% tithing, and the idea that we must gather in a church building instead of in each others homes like it was in the early church).
Not all Protestant churches are the same or unified on all things. The same is true even of Catholic churches (despite some of them saying otherwise). There are Charismatic Catholic churches and Protestant Charismatic churches. While I lean heavily towards Partial Cessationism (that the gift of apostleship has ceased, and the miraculous gifts have ceased, but not the gifts on teaching, and ministry, etc.), I do not want to say that every Charismatic Continuationist type Christian on the planet is not of God (Because I do not want to speak out out against God if I am wrong). Most of what I have seen in the Charismatic movement disturbs me greatly, and the biblical case for Partial Cessationism (called "Cessationism") is very strong.
The way of truth is to follow your Bible and to follow GOD alone.
Do not trust in visions, prophecies, added holy books, or dreams, etc.
I say this because only the Bible and GOD will guide you were you need to go spiritually. Do not follow anyone but GOD and His Word. Most today are seeking to follow their own way. Many today seek to justify sin on some level, as well. Many add things to the Bible that is not clearly there. These added things have not proven themselves to be trustworthy like the Bible.
To see some excellent evidences that back up the Bible as being divine in origin, check out my Blogger article here:
Love Branch: Evidences for the Word of God
I believe church traditions, and or added holy books (like: The Book of Mormon, or Divine Revelation of Hell, or Heaven is for Real, the five points of Calvinism, etc.) contradict the Bible and they cannot be proven to be divine in origin on the same level as the Bible, either.
