Last week of the "mono" heresies--the final attempt at "compromise" that was, too, ultimately condemned as heretical.
Monothelitism was a 7th century heresy originally conceptualized to be an olive branch to believers of Monophysitism. There were two reiterations of this; the doctrine of one energy (Monoenergism) and the doctrine of one will (Monothelitism). Ultimately, Monoenergism, Monophysitism and Monothelitism were condemned as heretical at the 680 Third Council of Constantinople.
