(I'm kidding. Or am I?)
But in the case of St. Sebastian, depicted here with St. Fabian with whom he shares a feast day, it just might be an appropriate exclamation for many Catholics. St. Sebastian is commonly depicted nearly nude in Western art, shot through with arrows. In this representation he is depicted clothed in what appears to be rather regal soldier's attire, holding the instruments of his passion.
January 20 is the memorial of St. Fabian and St. Sebastian
