Jesus made it clear that he did not want a hierarchical structure to carry his message. God has always been against the consolidation of power derived from some sort of global cabal.
Starting with the Tower of Babel, God was against globalism. Today their are hundreds of thousands of individually run churches. We used to criticize this arrangement as JW's. But the reason God wants this diffusion is apparent: If a particular association goes apostate and heretical, the damage is limited.
The structure is very flat, compartmentalized, and resistant to fundamental change. A fundamental change would be something like Mary is a co-mediator with Christ; or teaching that Jesus isn't the Mediator for the average Christian today. Mormons teach that unless you go through their priesthood, there is no salvation.
But, it could be something much simpler, like some local pastor imagining himself as an apostle receiving new and direct doctrinal revelations from God. Or, maybe some pastor does something to hurt a lot of people. In these cases, the congregation can get rid of him and and the damage is localized.
Jesus obviously encouraged individual acts of faith without coming under some ecclesiastical authority first.
