A lot of people believe that buddhism is not far away from vegetarianism, actually only buddhist monk and certain sincere laymen who practice mahayana buddhism relying strictly on vegetarianism. Well, let's talk about Christianity, was Christ a Vegetarian? Although i am a buddhist, but i like to read scriptures of other religion besides buddhism's, ok, this is what i found in Christian's Holy Bible:
Genesis 1.29: Then God said, “I now give you every seed-bearing plant on the face of the entire earth and every tree that has fruit with seed in it. They will be yours for food.
Genesis 9.4: "But you must not eat meat that has its lifeblood still in it."
Romans 14.21: It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.
Was Jesus a Vegetarian? I think so, the messages of Jesus is love and compassion, naturally Jesus never want to know that billions of animals live miserable lives and die violent, bloody deaths in factory farms and slaughterhouses. Therefore, no matter we are Buddhist or Christian, when we sit down to eat, we can add to the level of violence, misery, and death in the world, or we can respect the mother nature or creation of god with a vegetarian diet.
A vegetarian diet is good for your health and spares animals unimaginable suffering and violence, and of course will purify our mind and soul.
