i found this mending of a conversation between gregory of nyssa and his sister compelling as diana butler bass compares lessons from greg that michael vick could have used.
Macrina argues that human beings and “irrational animals” share common gifts from God, the ability to perceive and passions. What separates human animals from “irrational” ones is the capacity of free will, part of human ability to discern and choose. Thus, humans are given the responsibility to care for animals, as irrational animals are subject to human free will.
Gregory, quoting his sister, goes on to say: “For when reason does not control the impulse which naturally lies in them, the fierce animals are destroyed by anger because they fight among themselves.” Likewise, human beings who fail to discern and act upon what is good will be consumed by irrational sin. Gregory directly links human treatment and care for animals to acts of human violence, and implicitly develops a Christian theology of creation care.

The Michael Vick allegations revolt good people, those who believe it is wrong for a person to treat animals viciously. If proved true, Vick failed to meet even the basic Christian requirement to employ reason and free will to care for his dogs. But this case pushes further: What of the animals? What are the fundamental rights of the dogs to happiness and life? How can those rights be guaranteed and protected? (Interestingly enough, India’s highest court recommended a course for the construction of animal rights in 2000.) And how do religious people generate a vision for animal justice from their theological traditions?
