Never be afraid to speak the truth to those in power

A quote from the retirement letter of Sir Ivan Rogers to his staff. Sir Ivan, who retired earlier this week, was the UK's ambassador to the EU:

“I hope you will continue to challenge ill-founded arguments and muddled thinking and that you will never be afraid to speak the truth to those in power.”

A universal sentiment applicable to every organisation under the sun. Maybe especially today within relgious congregations.
