Ok...let me try to make my point a little more concrete...
flesh99 is using REASON (his knowledge of greek & hebrew), EXPERIENCE (the leading of the Holy Spirit (and I would imagine the revelation of God's presence during his day-to-day life), and TRADITION (the larger community of faith - in this case represented by his commentaries).
All aspects of this are playing together to lead flesh99 to what he understands to be the correct interpretation of God's Word.
If my experience directly contradicts with how I understand God's Word, then I have to work through that issue until they are reconciled--either I misunderstood the Spirit's leading and the experience God gave me, or I misunderstood the Word. If my understanding of greek (which is still quite limited) seems to contradict my understanding of God's Word, then I keep working until they are reconciled. If my quick reading of God's Word isn't in line with the best of Church Tradition and Christian Scholarship, then I had better be sure that I haven't mis-interpreted that Word and find myself teaching heresies.
And so, I would suggest that we all have other elements that help us interpret God's Word...things that help us understand if a particular passage is literal or figurative...dialogues with other scholars who help us know that our interpretation is within orthodox Christianity.
I only think that when we say to someone, "Sola Scriptura" we need to explain that we don't simply mean that the Bible speaks for itself and that it is our only authority. Yes, it may be our final authority...but God has given us other tools to experience His truth, and which help us understand His Word more fully.
Our dialogue with our Catholic brethren may be more successful if we are intentionally more honest about the various things that have authority for us, and help us understand God's Word.
That's where I was going with all that...I hope it made a little bit of sense!
Grace and Peace,
