If the cache is on a churches property (with permission and all that jazz) I see it as perfectly exceptable, but like said before I see it also as advertising otherwise., besides its supposed to be for all ages, and I believe you shouldn't promote religion to children......that's the parents responsibility, not all cashers are christian, or jewish, or muslim, or catholic, or wiccan, or buddhist, or native american, or pagan, or, or, or, so unless its on religious property leave it out
