Fรชted on this day on the anniversary of his consecration as the bishop of Milan in 374 AD, the statesman and theologian Saint Ambrose was a strong and influential proponent of heterodoxy in the Latin rite and was also celebrated for a cycle of Advents hymns and antiphonal chants that inform later traditions of carolling. Along with Augustine of Hippo (whom Ambrose converted), Jerome and Pope Gregory the Great, he is considered in western traditions a Doctor of the Church. Born in Augusta Treverorum around 339, it is said a swarm of bees descended on the infant whilst in his crib, leaving the baby unharmed and anointed with droplets of honey—taken as an auspicious sign and his patronage of apiculturists and by extension candle-makers. Moving to Rome from the provinces, Ambrose would study law and rhetoric and enter public service, like his father, becoming governor of Liguria and Emilia with the captial in Milan. Intervening in a succession crisis for the city’s bishop seat, not standing for the office, the politician accepted the vacancy compelled by popular acclaim of the assembled council, the Church afforded a measure of autonomy by Ambrose’s imperial connections, which tended towards deferment to his decisions and a level of independence. Charitable and advocating a kind of liturgical flexibility and rejecting rigid customs—including tolerance for pagans and other non-Christians, his advice to Augustine about respecting local ways stays with us, distilled as, “When in Rome, do as the Romans do.”
