A butterfly pin, given to Pope Francis by a woman who was forced into sexual slavery by the Japanese military during World War II was pinned on him before mass on Monday, Aug. 18, 2014. In a poignant moment at the start of the Mass on Monday, Francis bent down and greeted seven women, many sitting in wheelchairs, who were forced into sexual slavery by the Japanese military during World War II. After receiving the pin - a symbol of the plight of these "comfort women"  he immediately pinned it to his vestments and wore it throughout the Mass. (Daniel Dal Zennaro,Pool/AP) #
