And that is precisely how RC's "use" the bible. It's all a matter of "what can we get away with because it is not expressly forbidden".
I think you've deliberately read past me.
There is such a thing as a Scriptural inference, and they are drawn all the time, even by Christians who adhere to sola Scriptura.
I provided a Scriptural argument - as far as I can see, to deny that we can continue to request the intercession of our fellow Christians simply because they have experienced a physical death which Christ himself explicitly came to free them from is a position which requires a Scriptural defense in and of itself.
It is a legitimate matter of Scriptural debate, but I do not think I am "using" Scripture when I seek to assert Christ's sovereignty over death and the essential unity of His body, the Church.
I understand that you seek to defend a doctrine of Christ's sole mediation for the believer, and that you think that the intercession of the saints undermines it. I do not think you are "using" Scripture by refusing to consider the Scriptural description of what the Church is or the full implications of Christ's triumph over death.
I think that this issue is one on which their is no clear Scriptural decision for either position, but at the same time one which carries a wealth of suggestive Scriptural evidence.
