Dyothelitism or Dyotheletism (from Greek δυοθελητισμός "doctrine of 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.
The human nature of Christ cooperates with the divine will, as the Catechism of the Catholic Church, no. 475, states: "Similarly, at the sixth ecumenical council, Constantinople III in 681, the Church confessed that Christ possesses two wills and two natural operations, divine and human. They are not opposed to each other, but co-operate in such a way that the Word made flesh willed humanly in obedience to his Father all that he had decided divinely with the Father and the Holy Spirit for our salvation. Christ's human will 'does not resist or oppose but rather submits to his divine and almighty will.'"
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 Third 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.
