Triphysites
From BiblePortal Wikipedia
Triphysites [1]
(from Τρεῖς , Three, and Φύσεις , Natures ) , those divines who, at the fourteenth and fifteenth councils of Toledo, A.D. 684, 688, carried their opposition to the Monophysites and Monothelites to such an extreme that they declared a belief not only in Christ's distinct divine and human natures, but also in a third nature resulting from the union of the two.
