As humans we are beings in becoming, and what we will be is not yet revealed. Human essence is an eschatological reality that is fully realized in Jesus Christ, and is called forth in each one of us through him in whom humanity is fully realized. It is for this reason that human nature is notoriously difficult to define and profoundly amenable toward representation through a diversity of theoretical models. Being creatures whose essence is dynamic and inchoate we can be pressed into a variety of often competing models for rendering humanity intelligible. We are animals, the latest in a long line of evolutionary development; we are consumers, an economic being whose behavior collectively and individually can be predicted with an eye on market forces; we are social creatures constituted by institutional forces; we are angels fallen into flesh longing for transcendence and frustrated by physical limitations. What can’t be said about humankind? Certainly we are a mystery. But, we are a mystery deeply embedded in the mystery of Jesus Christ, who, as the first fruit of an eschatological harvest, has through resurrection power the authority to finally determine who we are and what we ought to be. In an essential way the final judgment is happening now in that we either find ourselves in his calling, or we utterly miss ourselves by turning a deaf ear to the call.
