Yes really. There's a whole lot of difference in what different folks get from the same scripture. Sola scriptura depends on whose interpretation.
If you are so down upon the scriptures and peoples interpretation, then how can you support external writings that were never accepted by the early church as “inspired”. Writings that introduces new thoughts and ideas to the Church. Forget the Sola Scriptura nonsense that goes on here. What exactly is your interpretation of what inspired writings mean?
