Today, as Hillary Clinton faces a confirmation hearing, she can be emboldened by the fact that this is the feast day of her namesake, St. Hilary of Poitiers. He was a strong opponent of Arianism, a heterodox movement sweeping the world in the 4th century; he stuck to the orthodox position through some very daunting times. Our next secretary of state will need to call upon similar resources of fortitude, in a world even more divided. (Some unsolicited political advice, though: Don’t say you were named after Hilary of Poitiers unless you are absolutely sure.)
