You can know church or ministry leadership has moved from biblical leadership to abusive control when:
They are consistently or persistently criticized or belittled, made to feel worthless and guilty even when they aren’t.
They are made to feel that only the leaders know what God wants, that their spiritual experience can never measure up.
They are expected to spend all of their free time with church people and not to look beyond leadership for counsel or input.
They are not permitted to make even little decisions in their own spheres of ministry, needing approval for every change no matter how small.
They are given mandates on what to wear, eat, watch, listen to, read, etc., or face ostracism.
