How do you sell your ad agency? If branding is your esse, you could try and take credit for that daring cross symbol as branding for christianity. Even Fidel Castro consults McCann advertising. Not sure how the two are related but it does make for an amusing thought of what the client might be saying in these meetings. "I like the circle symbol better, it didn't kill me.."
"McCann. You won’t be sorry you listened to us."
