I, seriously, cannot believe StarBucks put that on their cups. Did they have a come to Jesus moment?
No, they simply published somebody else's views on their cups. Their "The Way I See It" series (notice that this one is #92 which means that there are AT LEAST 91 other entries in the series) contains little statements of opinion from various people who have submitted them for publishing. That cup is a statement of the way Rick Warren sees it, and not at a a statement of how anyone at Starbucks sees it.
