Before the flood people were vegetarians,or at least they should of been according to God,for He said He gave them plant life to eat,and had not instituted the eating of meat yet,but it was after Noah and his family came off the ark that eating meat was then alright to eat.
After Noah and his family came off the boat,then God said every living thing shall be meat for you.
Then with the Old Testament a separation of clean and unclean animals.
The New Testament back to every living thing shall be meat for you,for the Bible says all meat is good,and nothing to be refused,if it be received with thanksgiving,for it is sanctified by the word of God and prayer.
Jesus ate fish,and some people think He ate Lamb at the passover,but Jesus said He did desire to eat with them,and drink with them,but He would not do it.
God warns us of the new age movement that will be a big control factor in the future,and they will unify the religions,and it will be an international law to abstain from meats,and a man and a woman cannot marry for population reduction.
So being a vegetarian will be pushed big time,and even bigger as time goes on.
But a person is not more moral for being a vegetarian,as many great saints have been meat eaters,for whether to eat meat,or not eat meat,has no bearing on our relationship with God,for He said He does not care if you abstain from meat,or eat meat,it makes no difference to Him.
In the world some would say it is more moral to abstain from meat,but to God it does not matter if you eat meat,or not eat meat.
Homosexuality and being a vegetarian are becoming popular,because there are people pushing it and influencing many people,but that is what they want because it will be the operation of the world in the future,being a vegetarian for sure as international law,but not homosexuality,but they can abstain from sex and a partnership,but a man and a woman cannot marry,but pushing homosexuality increases the chances that some will not desire the opposite sex.
