Apparently the Pope has said that one should guard against the "cynicism that considers mockery of the sacred to be an exercise of freedom".
What the Pope really means is that rational people should not point out to the intellectually dishonest and mentally feeble who believe in a religion of one stripe or another that their entire 'faith' system is the fruit of their delusional psychopathology and that they are being manipulated by charlatans, liars and scoundrels who no more believe in the utter crap they espouse to their demented followers than I do.
And in saying this I do not "mock the sacred", as the Pope would have it, for the fact is that there is nothing to mock that is sacred since all religions are just a complete fabrication from beginning to end. This is why the fundamental doctrine of the purveyors of all religions is encompassed by the Latin term 'sacrifium intellectus', the sacrifice of the intellect - silencing the voice of reason in favour of blind faith.
True freedom comes from being able to determine for oneself what is a moral and decent way to live, and having the integrity, courage, independence and self-sufficiency to do so. This was, after all, part of the original message of the Cynics in the 3rd century BCE.
