Theological Word of the Day: Monophysitism

Reclaiming the Mind Ministries has started a blog called Theological Word of the Day. And for me whose understanding of big theological words is (still) very limited, I find this very helpful. I appreciate the effort people put in this project. I put the widget on the sidebar, however, for my own benefit I am reposting the words here as well.

Monophysitism
noun (Greek mono-, one- + Greek phusis, nature)
The heretical belief that the two natures of Christ came together in the incarnation to make one new nature. Condemned in 451 at the council of Chalcedon. Chalcedon held that the two nature of Christ, human and divine, remain completely in tact in one person.
