Francis, who plans to dedicate his upcoming annual communications message to “fake news,” told Catholic media on Saturday that journalists perform a mission that is among the most “fundamental” to democratic societies.

But he reminded them to provide precise, complete and correct information and not to provide one-sided reports.

The pope said: “You shouldn’t fall into the ‘sins of communication:’ disinformation, or giving just one side, calumny that is sensationalized, or defamation, looking for things that are old news and have been dealt with and bringing them to light today.”
