Stop having priests and ministers (that are pedophiles or sexual abusers) preach that we are all sinners.

We are not all sinners, just as we are not all liars.  

Priests and ministers that are sinners cannot give the sacraments or any sacred duties, because sinners have compromised morals/no morals and therefore have no moral authority to do so.

Anything coming from them is meaningless and without holy substance.

Accepting sins and colluding with sinners is corruption and is therefore, unholy and damnable.

Thus to preach that we are all sinners (as if we can collude with sinners and be accepting of sins without damnation) is also unholy and damnable.
