Mansuetus of Milan

Saint Mansuetus was archbishop of Milan from 676 to 685. The Church commemorates him on 19 February, the day of his repose, probably in the year 685. Little is known about his life, but his ministry is tied to the Church's struggle against Monothelitism.

In 679 Mansuetus gathered a synod in Milan with his suffragan bishops to condemn the Monothelite teaching. According to Paul the Deacon, the synod sent a letter directly to the emperor Constantine IV, written by Damian, who later became bishop of Pavia. A year later Mansuetus and his bishops took part in Rome in the synod opened by Pope Agatho on 27 March 680 and signed its acts. That synod prepared the Third Council of Constantinople, which a few months later condemned Monothelitism.

His relics were buried in the Basilica of Sant'Ambrogio, then moved to the Basilica of Santo Stefano Maggiore, and in 1987 to the south transept of the cathedral of Milan. He is commemorated on 19 February in the Roman rite and on 2 September in the Ambrosian rite. A later tradition, with no historical basis, connects him with the Roman family of the Savelli.
