Thinking about chickens lately (ridiculous beasts that they are). And cows, which are one of my favorite animals.
My understanding of veganism is a rejection of the use of any animal-derived products, for food or otherwise (someone correct me if I’m mistaken).
I would want to argue that this is not a good ultimate goal for the sanctification of the world because, when the heavens and earth are remade, service and work will not be eliminated but rather blessed: ‘work’ is not a part of the curse, man’s work itself is cursed. Men will still plow and the earth will yield up its abundance into our hands, fulfilling a part of its own work and service before the Lord.
In the same way, the animals have services to render to God and Man, duties to fulfill which are not in and of themselves a hardship or a curse, but rather responsibilities which have been cursed because of Man’s sin. Like a tree bringing forth fruit or a woman bearing a child, fulfilment is not to be had in the mere act of reproduction (which is an oxymoronic phrase anyway): The Life given goes far beyond the individual being created (whether it be a baby or a bean sprout).
Thus, to reject the use of all animal products, including the eating of eggs, milk-based products, etc. is to devalue the work which may be a part of their fulfilment and thus to, ironically, denature the creature.
