Scripture...inspired but not dictated. Christ is the Word....the New Testament is man's documentation of that. Men make mistakes.
Sola Scriptura is to put our trust only in God and His Word, which is written by His prophets and apostles in one book and translated for us all to read for ourselves, to know of a certain, what God has spoken to us in the world for our faith, salvation, edification, and justification with Him.
And as the Scripture says, we do not put our trust in men, but only in that teaching by men confirmed as true by Scripture.
Scripture never tells us to put our trust in any man, nor in ourselves, nor even in any of God's prophets and apostles, and especially not in 'our leaders'. We are to obey them that bring Scripture of truth and true reasoning of Scripture, because the rule over us they bring is that of God and His Word.
Why then do those who reject Sola Scriptura on the basis of all men are flawed, which is true, and so none of 'Scripture' can be trusted as true on it's own, having been inspired of God, but no doubt written in flawed manner: i.e. not 'dictated' to them our of God's own mouth.
But then they proceed to put their trust in other traditions, and 'their leaders' that pass on those traditions not found in 'flawed' Scripture. And they never even question those traditions, nor those leaders as flawed. So much so, that to even suggest they should be judged by Scripture is heresy against their not-so-flawed leaders.
They won't put their trust in 'flawed' Scriptures, because the writers were flawed, but they do put their trust in unflawable traditions and leaders that teach them in unflawing manner?
Rejecting Sola Scriptura is to shut the door to the truth of God, which no man should shut, and to open the door to cultish idolatry in other things than Scripture, which no man should open. (Rev 3:8)
