I appreciate
@SolaScriptura on this matter. Very much. This thread and the other.
Yes, we come with received traditional grids, for better or worse. How good for us if our default mode of interpretation is built upon sound Scriptural principles hammered out by godly and learned men. The quality control of church history is invaluable. Still, it's Christ's own will that every tradition be held to Scripture, no matter how pious it sounds, or how helpful it may seem.
Christ himself called into question ritual handwashing in Mark 7. Many believed the tradition to have come from Moses. Who would dare question Moses? His spiritual privilege and wisdom was unlike any until Christ. The tradition itself reflected a desire to maintain spiritual purity, and to be separate from anything unclean. The tradition was held in high regard. Mk. 7:2, when Christ didn't do it, "they found fault." Who all kept the tradition? If it indeed came from Moses, then scores of godly men from Joshua to Joseph possibly kept it.
And yet to Christ, with no lack of love for Moses, the faithful servant in the house (if indeed the teaching came from Moses), it is merely "the teachings of men." (Mk. 7:7); not because there was no reason to think Moses actually said it, or because it lacked historical patronage, but because it is simply nowhere in "the teaching and to the testimony." It's serviceability as a reminder of the need for spiritual purity held no basis for its continuance whatsoever.
It's difficult to stand outside one's received tradition and question it, but it is doable. Was the Jew of that day stuck in a tradition of hermeneutic? The hermeneutic he would have grown up with would have justified the Pharisees and condemned Christ. There is no choice but to "step out," and at least faithfully modify the hermeneutic. In any case, he can't afford the conclusions he would have come to before.
In any case, whatever the reason for a tradition, the truth will always set free, and the Scriptures have all the truth necessary for life and godliness and for the Man of God to be complete and fully furnished. If it's not there, you don't need it.
