Bishops and priests who succumb to the temptations of money and the vanity of careerism turn into wolves “who devour the flesh of their own sheep”. Mincing no words to stigmatize the conduct of anyone who, the Pope said, citing St Augustine, “takes the flesh of the sheep to eat it, exploit it or trade in it, and who is attached to money, becomes a miser and frequently also a simonist”. Or else he makes use of the wool for his own vanity, in order to boast. Pope Francis, May 2013
This never reflects well on you, or your argument. It also plants the idea in the mind of your audience that perhaps people who believe like you all suffer from a weak and/or corrupt mind. This is not a fair observation, but it is a likely one. If you want to advance truth, you care more about effective persuasion than hurting your interlocutor.
