I’m sure I’ve linked to this before, but here’s an article by Stanley Hauerwas and John Berkman, “The Chief End of All Flesh,” which attempts to think theologically about our relationship to animals.
In Hauerwas and Berkman’s view, to say that humans have “dominion” over creation (and, thus, animals) means that “God has chosen humanity to be an image of God’s own rule in the world.” But to understand the nature of this rule requires that we reflect on how God rules over us. To be created in the image of God just is “to act as an image of God’s rule in the world”:
In Genesis 1, the image of God is part of the vision of a peaceable creation, both between human and animal and between animal and animal, a peace where it is not necessary to sacrifice one for the other. Similarly, for Christians to live as the image of Christ means to live according to the call of the kingdom of God. In Gethsemene – in taking up the way of the Cross-Christ shows us clearly that the way of the kingdom of God is not the way of violence. In reaching the ultimate end of all our strivings, in the peaceable kingdom of God, we shall finally live in true shalom with all creatures of God.
This eschatological orientation – that “nature” doesn’t exist in and of itself, but is directed to a purpose, namely, the consummation of God’s kingdom – gives shape to the distinctive Christian attitude toward non-human creation, say Hauerwas and Berkman:
Thus, we believe the church is faithful when it lives out the fact that nature has a sacred element, not because Christians wish to uphold or preserve nature for its own sake, but because nature is creation in travail, and, as such, has its own end to glorify God, rather than to serve humans. Thus, Christians must strive to live the relationship between human and animal life in terms of the common end being life in the peaceable kingdom, the kingdom of God.
This isn’t romanticism about “pristine,” “unspoiled” nature, an attitutde that at least some animal rights proponents seem to fall into. Nature is indeed “red in tooth and claw,” but it’s telos is to be redeemed as something different – a new heaven and a new earth. And so it’s not so much that animals have a kind of intrinsic value, much less rights, as that animals exist for God’s sake, not humanity’s sake. That animals have their own purpose in God’s ordering of the world implies that there are limits to the way we can permissibly treat them.
Unsurprisingly for anyone familiar with Hauerwas’s other work, they connect our attitude toward animals with the question of pacifism. Living non-violently, both with other humans and animals, is a witness to God’s coming reign. “So Christian vegetarianism might be understood as a witness to the world that God’s creation is not meant to be at war with itself.”
Hauerwas and Berkman concede that many Christians will not go this far, but they say that, analogous to the proponent of the just-war tradition, any proponent of “just meat-eating” bears the burden of proof. Both presuppose that “nonviolence is the fundamental stance of Christians” even if they’re willing to entertain exceptions.
Here they go farther than I’m willing to go. I don’t think it’s meat-eating itself that is the problem so much as how we treat animals while they’re alive. If animals have a role in God’s plan that isn’t exhausted by serving human ends, then I think we have a responsibility not to treat them in ways that violate their God-bestowed integrity and dignity. In a similar way, while not convinced of the pacifist stance, I think there are limits to what can be done in the course of waging even a justified war, such as prohibitions on torture, respecting non-combatant immunity, etc. Respecting those limits can also be a sign that survival doesn’t trump all other values and that our hope is in a kingdom to come.
