How to avoid gossiping? Bite your tongue, bite your tongue! Sure, It will swell, but you’ll have done a good thing. Some people who should set an example, are not doing so when they chatter.” --Pope Francis
In a talk to Vatican Employees, the Holy Father condemns chatter, gossip, but His Holiness' entire talk is itself chatter about the Vatican clergy and their peccadilloes and things the Holy Father himself has heard from other employees at the Vatican which His Holiness shares with everyone in the whole wide world!
This is fascinating to say the least. I once heard that preachers, be they Catholic or Protestant condemn in others what they themselves are the most guilty of doing.
