Jesus summoned the Twelve and began to send them out two by two. So they went off and preached repentance. The Twelve drove out many demons, and they anointed with oil many who were sick and cured them. (Mk 6:7-13)

Healing the sick is a part of the apostolic mission as Jesus sends out the Twelve. Today is the Feast of Saint Blase with the custom of the Blessing of Throats. Two crossed candles are used for the blessing.
