Like the ascension of Mary for instance? Is that where they rely on scripture? Those teachers you rely on have given you scriptural proof of the ascension of Mary have they? I suppose they have given you scriptural proof of praying to those who have passed on rather then Jesus words that there is no other mediator but Him. I suppose they have specific passages that they use to show that its not just those who are living who should pray for each other.
In other words, if you want to take cheap shots, do your homework first. The phrase you want is the "assumption, NOT the "ascension" which is theologically a very different thing.
Also, I have already dealt with the matter of the intercession of the saints (including you and me.) The chapter of Timothy which speaks on the one mediator starts with an statement that we all should mediate and intercede. And Paul's discussion of our being 'in Christ' suffices to show that neither we nor Mary are intercessors or mediators on our own but because we are "in Christ."
And then it would be the teachers who would provide the hermeneutic.
