Funny, that's what the Pharisees said.
Yet Christ was big on submitting to their authority, unlike Luther, Calvin, Zwingli, Henry VIII and their followers.
1 Then Jesus spoke to the multitudes and to his disciples, 2 Saying: The scribes and the Pharisees have sitten on the chair of Moses. 3 All things therefore whatsoever they shall say to you, observe and do: but according to their works do ye not. For they say, and do not.
-Matthew 23:1-3
What does a passage on spiritual hypocrisy have to do with Tradition with a capital T?
First of all, then why have you not done the same?
Secondly, He submitted to their authority only so far as it did not overstep or annul the Scripture, specifically the Torah. When they tried to condemn His disciples for eating a snack along the road on the Sabbath, did He submit to their judgment, or point out why they were wrong? Ditto when they condemned Him for healing on the Sabbath or His disciples for not ritually washing their hands before a meal?
You're trying to have it both ways here: You would (I presume) agree with the Church's decision to separate from the synagogues when the persecution of believers in the Messiah became too great, but you condemn those who left the RCC when the persecution of Biblical Christians became too great.
Remember, Luther didn't leave the RCC on his own accord. He was kicked out for attempting to reform it over the issue of selling indulgences.
