And Catholics submit to whom ?
To the Head of the Body, Jesus Christ. However, we do so knowing that Christ left people in charge on earth over the community. That is pretty clear in the Scriptures.
Of course, Protestants submit to Jesus Christ as well, ... though we are persuaded that we can be more direct with Him (with less middle managesment, perhaps) ... than Catholic tradition suggests.
Meanwhile, Protestants hold to their own personal interpretations, which is subject to change, depending on the mood that strikes them. I am sure that God presents Himself to people in this manner, but it is not the means He gave His apostles in the Scriptures.
This really is a mischaracterization of Protestant belief and practice.
Protestants, for the vast majority, believe their preachers and teachers, and are homogenous regarding the core doctrines of Christianity (i.e. as they are found in the Apostles, Nicean creeds, etc.).
You know that is not true. You ultimately subject yourself to your current understanding of Scriptures. Thus, if a pastor begins to teach something that doesn't sound right to a Protestant - they disagree for whatever reason - then they can and do opt to leave the congregation and go elsewhere until they find someone that fits THEIR particular paradigm and understanding of the Gospel. Thus, in the end, you follow only as long as you agree with the shepherd. Who then are you obeying?
By the way, this conversation is not directed at you personally, but a discussion about the Protestant mindset in general.
