The lack of a centralized hierarchy in the Protestant churches is the probably the primary reason they basically became state religions; they shifted as popular cultures did. There is no biblical excuse for female clergy, for example; Jesus Christ certainly wasn’t sexist, yet he chose only male apostles (and bestowed certain powers/responsibilities on them). There certainly is no biblical justification for normalization of homosexual relations, either.
State religions? You don’t know much of roman catholic history do you?
There are biblical injunctions against bowing down to idols yet Catholics bow down before idols of Mary.
