Here's the thing: the unit of reverence in Europe is the family which is why a child born today of unmarried parents in Sweden has a better chance of growing up in a house with both of his parents than a child born to a married couple in America. Here we revere the couple there they revere the family.
There must be something solemn serious and tender about any attitude which we denominate religious. If glad it must not grin or snicker if sad it must not scream or curse.
