Anyone who has studied church history knows that it is not a democracy but instead has for most of its history a very vertical-oriented top-heavy organization. When the leadership of the church said something everyone was expected to quickly get in line with no questions asked.
Dissension, or some might say freedom of speech, is simply not allowed. In the past, anyone who even hinted at a disagreement was quickly handled. In the first few centuries of the church, many were proclaimed to be a heretic, which basically meant they didn’t agree with the leadership in some way or another. It usually followed that all of their writings, if they existed, were burned so their words would not pollute the church. And some were burned along with their books.
Thank heavens at least in the last few centuries heretics are not so severely handled but that does not mean that they are now ignored. Many think only of the Catholic church when they think of the power structures. No Catholic, especially the cardinals and bishops would go against anything that the Pope proclaims. But this situation also occurs amongst the Protestant denominations as well. Plainly speaking the leadership is to be obeyed.
If you even hint that you don’t agree with all the various creeds and statements can cause you to be disciplined or even thrown out. I know personally of a Lutheran minister who was brought back from an overseas mission and stripped of his sermon rights because he dared to join in prayer with other Christian groups, and years later I like him was shown the door due because I didn’t tow the line on how old the earth is among other things.
Many just can’t accept any questioning of their proclaimed doctrine. They claim that it would stain their institutional purity. About the only denomination that I am aware of that doesn’t do this are the Quakers. But since they are adamantly opposed to creeds, in general, that seems natural to them.
Sadly, there is simply no such thing as freedom of speech inside most church doors…
