"The biblical case for vegetarianism does not rest on the view that killing may never be allowable in the eyes of God, rather on the view that killing is always a grave matter. When we have to kill to live we may do so, but when we do not, we should live otherwise. It is vital to appreciate the force of this argument. In past ages many – including undoubtedly the biblical writers themselves – have thought that killing for food was essential in order to live. But … we now know that – at least for those now living in the rich West – it is perfectly possible to sustain a healthy diet without any recourse to flesh products. … Those individuals who opt for vegetarianism can do so in the knowledge that they are living closer to the biblical ideal of peaceableness than their carnivorous contemporaries. The point should not be minimized. In many ways it is difficult to know how we can live more peaceably in a world striven by violence and greed and consumerism. Individuals often feel powerless in the face of great social forces beyond even democratic control. To opt for a vegetarian life-style is to take one practical step towards living in peace with the rest of creation. One step towards reducing the rate of institutionalized killing in the world today."
