"Sister Helena of the Transfiguration"
As a nun, Sandy follows the Catholic convent tradition of taking the name of a saint that she wishes to emulate.
Saint Helena (246/250-330), also known as Helena of Constantinople, was the mother of Constantine I and is credited with having located a number of Christian relics of the True Cross.
It is also said that in the 4th century she erected a church on Mount Tabor, which is believed to be the site of the Transfiguration.
The Transfiguration of Jesus is one of the miracles referred to in the New Testament of the Christian Bible. It refers to the occasion when Jesus became radiant, spoke with the prophets Moses and Elijah, and was addressed directly by God the father.
