I expect what he means by that is that he would like us to stop thinking that nothing he says or does can be taken at face value because, like any good closet liberal, he will cheerfully dissemble until he gets his way.
I have an idea: I will continue to believe that nothing Welby says or does can be taken at face value but, during Lent, I will call it Good Cynicism. That way, everyone is happy.
From here:
The Archbishop of Canterbury’s urged fellow leaders in the Church of England to give up cynicism for Lent and to show more love towards those they disagree with.
Speaking at the start of a meeting by General Synod, Most Rev Justin Welby admitted members disagree on issues such as “inclusion”.
He said: “As we journey towards Lent some of you may be considering what you might give up during the penitential season.
“I urge you to consider especially as members of General Synod giving up cynicism and renewing love for those with whom you and I differ.”
