In the Bible and in churches, Jesus is represented as a lover -- a bridegroom and his followers as a bride. When I look at these actual church signs I can't help but think these are intentional. The last one cracked me up. Come on. No adult can be that extremely naive, or can they?
I think a bit of both but some like a "4 inch tongue can bring a 6 foot man to his knees" definitely intentional.
I picked "other" because it could be a manifestation of them having sex on the brain while actively promoting erotophobia.
