When sola-scriptura involves inumerable different interpretations some of which give us 'churches' that bless gay marriages, ordain gay bishops, promote abortion for the poor, etc. It's clear that even if your allegations are true (that the church has overiden scripture, which I don't buy it has) it's preffereable to every joe schmoe overiding Scripture with his 'personal interpretation'.
Sola Scritura does not mean there are many paths; it means there is one path and we are to diligently strive to know it.
You continue to miss the point of Sola Scriptura. Sola Scriptura testifies to the singular truth of God and that that truth is found in Scripture because the Holy Spirit resides there and will instruct the elect. The elect's earthly instruction can be a circuitous route, just like Paul's, but the elect should be "certain that eventually their election by God will catch up to their lives in real time," as b-d once said so well. And the elect will know their election by the indwelling Holy Spirit who guides them through the Scriptures, sanctifies them, comforts them and leads them in righteousness.
Sola Scriptura does not mean everyone understands everything in the blink of an eye. It means we are to search the Scriptures and be confident that therein we will find our salvation.
To deny that the Scriptures contain all we need to know of God is to deny the work of the Holy Spirit.
