Every year on St. Blase's feast, two
candles tied with ribbon in the shape of an X are used to bless
throats. In the prayer the Church prays that those blessed may be
delivered from diseases of the throat and from every other illness.
Candles are used because of another story: It is said that while Blase
was kept in a dark prison, a woman secretly brought him some candles
and food.
Blase is one of the Fourteen Holy Helpers, saints who were patrons for
almost every aspect of life. People in the Middle Ages showed devotion
to these saints as a group. internet
