Years ago I remember a court case where a local church had a sign that read "Jesus Saves". The grocery store across the street had a sign which used the company's regular slogan: "Safeway Saves More". I think there was a court case and the grocery store won.
In that spirit of contextual punning, I offer this Church Sign Generator fun link:
