Traditions of the Apostles came first, the Scriptures came next. God gave His Gospel orally first. The Apostles gave it to others orally first. The Scriptures didn't come until AT LEAST ten years later, if we believe that an Aramaic version of Matthew was written in the early 40's. Thus, the first ten years at least saw Christianity spread without any Gospel writings, any Epistles, etc. Later, when these same men of God wrote letters and the narratives of the Gospels, they naturally taught the SAME thing that they taught orally earlier to others. Thus, the oral teachings preceded the written ones, and the written ones did not overturn the oral ones.
I am responding to your post questioning whether the very words of Jesus were contained in the Gospel of Luke. Do you believe that the Holy Spirit inspired the writings of scripture or not? Do you believe Jesus told his disciples that the Holy Spirit would bring to their remembrance all the things he had taught them? If you do, and it sure sounds like you do since the above quote was from YOU, then I cannot see how you can deny the teachings of Christ concerning Hades from Luke 16.
First of all,Of course I believe the Scriptures are inspired,I don't accept protestant interpretations as inspired when they disagree with Church teaching
Secondly, my point is that TRADITIONS came first,so I'm not denying Christ's teaching.
The Apostles followed what Christ said before it was WRITTEN-They Did WRITE first and act later,thus tradition came first
