The Divine Mother wanted members of Cafh to have an original name, and the Regulation calls them Sons.
While other Orders have name their members brothers, with a prevalence of the link of those that are united by one and the same faith or ideal, Cafh does not make prevail the link of members among them, which could give rise to the word “brothers”, but the link between members and the Divine Mother: Sons and Mother, Sparks and Fire, Rivers and Sea.
