Pope Francis is trying to address gaps in the regulatory processes of the Catholic Church. But clergy can still decide whether, and to what degree, to share information.
Pope Francis has discouraged homosexual men from entering priesthood. Prior to the 12th century, even celebrated priests could write about same-sex desires and the church paid little attention.
In the fourth century, Christian churches in North Africa faced a crisis of trust. A separate church of the Donatists emerged that lasted for centuries.
While Pope Francis has publicly acknowledged sexual abuse by clergy, the hierarchical structure of the Catholic Church still makes it difficult to report and address cases of abuse.
In the Catholic understanding, priesthood is not simply a job that a someone can be fired from. Ordination is a deeply spiritual ceremony that is believed to transfer the power of the Holy Spirit.
Pope Francis is meeting bishops for a global summit to discuss sexual abuse by clergy. Such a response, says an expert, is part of a past pattern, unlikely to bring a lasting change.
There is rich Catholic heritage of resistance. Catholic protesters have used powerful religious symbols, including vials of their own blood, as an extension of Christ's blood, to demand change.
While the problem of priestly abuse might be centuries old, its modern paper trail began after World War II, when 'treatment centers' appeared for rehabilitating priests. Many were send to New Mexico.
Early Christians were open to marriage for priests. It wasn't until the 12th century that celibacy became mandatory in the Catholic Church.
