Council of Hatfield
The Council of Hatfield was a Christian convocation held in 680 in Hatfield, Hertfordshire in England to examine the English branch of the church's orthodoxy on Monothelitism. John of St. Peter's, a colleague of Benedict Biscop's at Wearmouth Abbey, was Pope Agatho's delegate. Archbishop Theodore led the council, where Monothelitism was rejected in favor of the orthodox Christological view that Jesus Christ has two wills corresponding to his two natures. The Council of Hatfield also included the Filioque into Nicene Creed.
