"...The hierarchal culture of the institution needs to be dismantled, he said."
The very hierachical structure is on its face a calculated structure of sexual abuse because it premises that females are secondary (inferior) to males before God. This presumption sets women up for abuse by males, as history documents, and as still occurs.
This fact alone requires dismantling of the hierarchical structure if the root causes of sexual abuse within Church are to be exposed and extirpated, and the Church is ever to have credibility.
