Let me break this down and see if I can make sense out of it.
(Translation)
If you receive all your faith from the Bible, why is the Church called the foundation and pillar of truth?
Where do you find that?
In the Bible. Peter I think. I'll find it for ya.
1 Cor 3:11 For other foundation can no man lay than that is laid, which is Jesus Christ.
Eph 2:20 And are built upon the foundation of the apostles and prophets, Jesus Christ himself being the chief corner stone;
So which is it? Is Jesus the foundation or is it the apostles and prophets? We know Peter can't be "the Rock" cause the Bible calls Jesus "The Rock" elsewhere. So why can "the foundation" be two different things in two different places?
My foundation is in Christ, then his word helps me to better understand what he wants of me and how I should conduct my self, and who he is.
Let me say this, if all the Bibles were destroyed, I would not loose my faith, since I have already established what I believe.
I don't know another way to answer this, but if it's not satisfactory, it's not because I'm avoiding it, it's because I don't understand it.:-)
I think it's because you redefined the question again. It is not about where your faith comes from, it is about the logical conflict in Sola Scriptura. I'll break it down.
Sola Scriptura is the idea that Scripture is the ultimate judge of everything else. It is the "last chance to get it right" appeal to which all Christians should listen. Scripture is what sets the standard of what is good and what is bad. What is true and what is false is determined by our inspired reading of Scripture. God and Scripture decide things together working in our hearts. Scripture is the source of all that is true.
Scripture itself calls the Church the "pillar of truth." This is in direct conflict with the idea of the Bible being the pillar of truth that is Sola Scriptura.

The Congregatin is the pillar of truth (that which holds up truth). This is so because the Congregation is the collection of believers. It is the Body of Christ, And Christ is the head of that body. It is no different to say that Jesus stands over the Congregation or is held up by the Congregation. Your version attempts to coopt a spiritual truth and twist it into a carnal want. The clergy is not the Congregation, it is a part of the Congregation. And an institution is not what is being discussed here.
