From Benedict XVI’s latest essay:
The extent and gravity of the reported incidents has deeply distressed both priests as well as laity, and has driven more than a few to call into question the very Faith of the Church. It was necessary to send out a strong message and seek out a new beginning, so to make the Church again truly credible as a light among peoples and as a force in service against the powers of destruction.
In other words…
Make The Church Credible Again!
The powers of destruction are discussed in his essay. They are, as you might anticipate, long-standing themes, tropes of Ratzingeriana, including the Three Enemies of the Soul as well as the Dictatorship of Relativism.
