Dyothelitism (a Greek loanword meaning "two wills") is a particular teaching about how the divine and human relate in the person of Jesus, known as a Christological doctrine. Specifically, Dyothelitism teaches that Jesus Christ had two natures and two wills. This position is in opposition to the Monothelitism position in the Christological debates. The debate concerning the Monothelite churches and the Catholic Church came to a conclusion at the Sixth Ecumenical Council of Constantinople in 681 CE. The Council declared that in line with the declarations of the Council of Chalcedon in 451 CE, which declared two natures in the one Person of Jesus Christ, there are equally two "wills" or "modes of operation" in the one Person of Jesus Christ as well.
