Abstract
A great many philosophers and theologians have recently maintained that we ought to adopt the following interpretation of the Christian Church’s proclamation that Jesus Christ is perfectly human and perfectly divine:(1) The one person Jesus Christ has every essential property of the kind humanity and every essential property of the kind divinity,where F is an essential property of a kind k just in case there is no possible world in which something belongs to k yet lacks F. I argue that these writers need to do much more work if they are to convince us that their view is rationally preferable to rival interpretations of traditional Christology. To be specific, they must try to persuade us that (1) plays an indispensable rôle in our best available explanation of how Christ’s life, death, and resurrection atone for our sins.
