St Apollinaris, first bishop of Ravenna and disciple of St Peter, preached Christ amid fierce persecution, enduring exile, torture, and martyrdom. A true shepherd, he ruled by serving, bearing witness through suffering. St Liborius, bishop of Le Mans, laboured in peace and charity, building up the Church in Gaul. Both saints model apostolic humility and pastoral courage, calling today’s bishops—and all of us—to steadfastness, sacrifice, and fidelity to Christ.
