The primary Catholic argument against sola scriptura is that the Bible does not explicitly teach sola scriptura. Catholics argue, “the Bible nowhere states that it is the ONLY authoritative guide for faith and practice.” While this is true, it fails to recognize a crucially important issue. We know that the Bible is the Word of God. The Bible declares itself to be God-breathed, inerrant, and authoritative. We also know that God does not change His mind or contradict Himself. So, while the Bible itself may not explicitly argue for “sola scriptura,” it most definitely does not allow for traditions that contradict its message. Sola scriptura is not as much of an argument against tradition as it is an argument against unbiblical, extra-biblical and/or anti-biblical doctrines. The only way to know for sure what God expects of us is to stay true to what we know He has revealed – the Bible. We can know, beyond the shadow of any doubt, that Scripture is true, authoritative, and reliable. The same cannot be said of tradition.
