Callista and Christa
Callista And Christa (Or Calliste And Christe, Christina, Etc.) were two sisters who had lapsed, and to whom Dorothea was intrusted, with orders that they should induce her to give up her faith. She, however, converted them. They were tied back to back, and thrown into a boiling caldron. There is a Calliste commemorated Sept. 1, in the Byzantine calendar, as having suffered martyrdom with her brothers. SEE CALOJERUS.
