Smoke in the Temple of God

We believed that after the [Second Vatican] Council would come a day of sunshine in the history of the Church. But instead there has come a day of clouds and storms, and of darkness ... And how did this come about? We will confide to you the thought that may be, we ourselves admit in free discussion, that may be unfounded, and that is that there has been a power, an adversary power. Let us call him by his name: the devil. … It is as if from some mysterious crack, no, it is not mysterious, from some crack the smoke of Satan has entered the Temple of God.

--Pope Paul VI, Address, June 29, 1972, On the Occasion of the Ninth Anniversary of His Election.
