St. Blasius was Bishop of Sebaste in Armenia. He was martyred in the reign of Licinius
(316). His miracle was saving a boy from choking on a fish bone which is why we get our throats blessed tomorrow. Be careful eating fish. Here is the blessing, which I hope you all hear.
"Per intercessionem S. Blasii liberet te Deus a malo gutteris et a quovis alio malo" (May God at the intercession of St. Blasius preserve you from throat troubles and every other evil).
