Angels and mermaids - testing the Genevan waters

So here are some of us tasting and testing Geneva water and also getting the artist Tom Tirabosco to personally decorate one of the water carafes for the WCC general secretary Olav Fykse Tveit. When Tom heard that we were from the World Council of Churches he changed the picture he was drawing from a mermaid to an angel, even adding a halo! Not quite sure what this means about the idea people have of religion.
