No - it is the Holy Spirit "who will guide you into all truth" John 16 as long as man-made traditions in the RCC or Calvinism are not standing in your way.
And so in Mark 7 the point is soooo incredibly obvious that they do not ask 'whose interpretation are you using?"
==============================
Nothing in Christ's statement to the magisterium in Mark 7 claims "this is not from scripture but from the church".
Mark 7
7 Howbeit in vain do they worship me, teaching for doctrines the commandments of men.
8 For laying aside the Commandment of God, ye hold the tradition of men, as the washing of pots and cups: and many other such like things ye do.
9 And he said unto them, Full well ye reject the commandment of God, that ye may keep your own tradition.
10 For Moses said, Honour thy father and thy mother; and, Whoso curseth father or mother, let him die the death:
11 But ye say, If a man shall say to his father or mother, It is Corban, that is to say, a gift, by whatsoever thou mightest be profited by me; he shall be free.
12 And ye suffer him no more to do ought for his father or his mother;
13 Making the Word of God of none effect through your tradition, which ye have delivered: and many such like things do ye.
Nor does Christ make the circular argument "your doctrine is unholy because it is unholy" -
This is a "not so subtle point" that keeps getting glossed over. circular arguments don't work.
Nor does Christ say "you do not have your scripture confirmed by an outside source"
Nor does Christ say "ignore the scripture I am quoting to prove you are in error"
We are talking about slamming the traditions of the church via the Mark 7 method - sola scriptura - where it is found to be in conflict with the Word of God.
Christ makes no appeal to Tradition in that text above - rather He appeals to scripture to hammer tradition.
No Jew in Mark 7 would respond "I see you appeal to Catholic tradition in that statement"
