Thank you for your inquiry and for sending us the article.
Let’s first look at God’s creation and heavenly intent. We know that there was no death in Eden, thus no eating of flesh, as the article concurs. Jesus tells us to be perfect as our heavenly Father is perfect (Matthew 5:48), and in 6:10 He tells us to pray for our Father’s heavenly will to be done on earth as it is in heaven, and in verses such as Revelation 21:4 we see that in the new heaven and earth there is no death thus no eating of flesh. This is God’s intent and it has never changed, as Isaiah confirms in his vision of the peaceable kingdom (11:6-9).
Paul also picks up on this Godly intent in Romans 8:18-23 where he tells us that the whole of creation groaning and anxiously waiting for the children of God to free it from its present corruption. Killing and flesh eating are all part of the corruption of this world, which would exclude those who partake of the corruption from being these children of God.
If we go back to Genesis 8:21, we see that God said that man was evil from his youth, because Noah sacrificed some of the animals on the ark. Thus Genesis 9:1-5, if anything, is only a concession to limit the depravity of humans. God provided enough food on the ark for every human and animal to be vegan, and He surely provided enough for them to live once they settled back on dry land. We also know that the dove brought back an olive branch, which clearly tells us that there were plants and trees growing by the time they got off the ark. They chose to kill and eat flesh against God’s will.
Those who try to excuse away the killing and eating of flesh are only falling into the trap set by the devil who corrupted the earth.
God clearly wants us to be vegan.
We hope this helps.
In the Love of the Lord, Frank and Mary
