Catching Meddlers

Here’s a great quote from George Orwell that could apply to preaching or any other communication endeavor,

The great enemy of clear language is insincerity. When there is a gap between one’s real and one’s declared aims, one turns as it were instinctively to long words and exhausted idioms, like a cuttlefish spurting out ink.

How do you think this might apply to communication within the Church?
