“As there were two natures in Christ [Divine and human], so there were two natural operations. [Divine and human, e.g. a Divine Will and a human will]” Pope Severinus  (Quoted by Horace K. Mann in his work: “The Lives of the Popes in the Early Middle Ages, Volume 1: The Popes Under the Lombard Rule, from St Gregory I (the Great) to Leo III, Part 1” (London, 1912) pg. 349)
