As Brian Wright put it, "The difficulty of creating fire is reflected in the importance of the perpetual fire. In many religions all over the world...In many cases great importance was attached to keeping the ritual fire pure and uncontaminated, and since those chosen to tend such sacred fires had such an important role in religious practices, they too were expected to be pure and of high moral virtue." (Wright, Brian. Brigid: Goddess, Druidess and Saint. Stroud [England]: History, 2009. 77.)
