At some point in an ecclesiastical hierarchy someone is manipulating people for their own benefit, knowing they're doing so. They profess miracles while knowing there are none.
Above a certain level all you'll find are charlatans.
The only religions that do not operate like this are unaffiliated churches, mystical, or nontheistic religions like Buddhism, Jainism etc.
If you profess a god and have a hierarchical structure your leaders manipulate you for their own gain or prestige. They do not believe.
