The idea that mans dogma was more important than the doctrine that you find in the actual Bible - was addressed by Christ here -
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.
That is a case of Christ demonstrating the way that the magisterium is hammered "sola scriptura" in the cases where it's traditions and "doctrines of men" are at odds with scripture.
[FONT="]The elders are in fact the "magisterium" even Paul admits to this.
Then Jesus spoke to the crowds and to his disciples, saying, “The scribes and the Pharisees have taken their seat on the chair of Moses. Therefore, do and observe all things whatsoever they tell you, but do not follow their example. For they preach but they do not practice. (Matthew 23:1-3)[/FONT]
