Abstract
John of Ripa’s (fl. 1350s) Christology is highly unusual in the context of late medieval theology, since it is a form of the old “homo assumptus (assumed man)” Christology found in St. Augustine and the Victorines, but not generally in later theologians. Ripa explains the Incarnation by supposing that the divine essence is in some sense the form of the human nature, such that both “God” and the whole panoply of divine properties can be predicated of it. This move allows Ripa to secure the truth of claims mandated by the authoritative Council of Chalcedon, such as “this human being is eternal.” Ripa appeals to a kind of relative identity to argue that the human being is (non-classically) identical with the divine person, such that positing something that “is God, but not the deity” does not result in an additional God or additional divine person.
