Sola Scriptura makes perfect sense because it's the God breathed, Holy Spirit inspired Word of God, is Truth, and stands alone as such. It is consistent with itself and within itself.
It doesn't need the stamp of approval of men to validate it.
It being the very words of God to us is not enough to make it authoritative for you, then I don't see that anything else would.
And the charges of bibliolatry fall flat as no one has ever built a statute of the Bible or put it on a pedestal and bowed down to it and burned incense to it, or lit candles to it.
Where was it found? In a cave?
True, but the argument is that since SS - that Scripture as the wholly inspired word of God (it uniquely is the only wholly inspired substantive body of Truth) alone is the supreme and sufficient standard/rule authoritative source of Truth for faith and morals - requires that Scripture provides all that is necessary for faith and morals then it must provide a canon, yet this is based upon a strawman of SS that restricts what it provides to formal explicit teaching (such as a sermon like Acts 10:36-43 by which one can become born again), and excludes what it materially provides such as by way of sanctioned substantiation, and which includes reason, the guidance of the Spirit and discernment as to what is of God, the church and teaching office,etc.
The opposing alternative essentially is that the church of Rome is the supreme and sufficient source of Truth, providing Scripture and the oral word of God as alone possessing ensured perpetual magisterial infallibility, which is necessary to assuredly know what is of God and its meaning. See post above.
However, it is manifest that even "lay people" assuredly could discern what is of God, both men and writings, without an infallible magisterium, and even in dissent from it (which is hopw the church began), and which in principle therefore provides for a canon. Indeed, most of what we hold to be Scripture was already established as being of God before a church of Rome even presumed it was necessary for this. Moreover, the premise of ensured perpetual magisterial infallibility is unseen and unnecessary in Scripture. God provided and preserved His word and faith without one, and often preserved faith by raising up men from without the magisterium and even in dissent from it. Which again, is also how the church began. (Mk. 11:27-33)
Thus the NT church began contrary to the Roman basis for Truth, and as is abundantly evidenced, the word of God/the Lord was normally written, even if sometimes first being spoken, and that as written, Scripture became the transcendent supreme standard for obedience and testing and establishing truth claims as the wholly Divinely inspired and assured, Word of God.
