No, Paul said that those who order others to completely abstain from meat, are heretics
>Forbidding to marry, to abstain from meats, which God hath created to be received with thanksgiving by the faithful, and by them that have known the truth.
>But we have no right to modify the genetic code of animals and pump them with steroids. We have no right to keep them in dark cramped detestable confines.
we have every right to do it. In fact, Jacob did genetic selection with help of God.
God doesnt need anything, He is perfect and self-sustaining. All that exists is created for us to use. Another part is ruining it, which is simply retarded (no ruler, that isnt complete moron ruins his own kingdom), but what you states has nothing to do with it. I better have thousands of cows to die and rot in dark confines if it means that at least one human in Africa or any other continent, made in image and likeness of God, will have something to eat.
