For many people today, practical atheism is the normal rule of life...If this attitude becomes a general existential position, then freedom no longer has any standards, then everyting is possible and permissible.

Evil too, will always be part of the mystery of the Church. And when we see what men, what the clergy have done in the Church, then that is nothing short of proof that he [Christ] founded and upholds the Church. If she were dependent on men, she would long since have perished.
