In my opinion its a believe, that every body is born as great as Thomas Aquinas.
Every body is able to find out the Trinity, the Deity of Christ, and many other doctrines, just reading the Bible alone.
Its a believe in Constitution without the Court of Law.
Its a believe in Christianity without the Church.
In the Church History the most learned Scholars were gathered for the Councils to acknowledge the truth which is written in the Holly Scriptues , but Sola Scriptura is a believe that every individual can take his Bible and decide by himself and for himself whether the writtings which he reads and translate were doctrinally correct.

Every individual by the Spirit of Discerning is so able that he can learn the Judaistic traditions and all ancient meanings and terms, even being ignorant of the Historical context of those writings.

I think that without the Church Cathechism, very probable that we shall read things into Scripture that are not there and miss things in Scripture that are there.
Therefore the Scripture REQUIRES and DEMANDS the Church.
