I have come across a few things written by people claiming to be Orthodox Jews who are vegans. One cannot be both, since no vegan can follow the laws put in place by God. Vegans remove the uniqueness of man and places all life on equal footing, which cannot be found anywhere in the Torah.
My Jewish Learning states that Orthodox Judaism is based on its adherents belief the Torah was given to the Jewish people in a mass revelation at Mount Sinai and that the rabbinical tradition (known as the Oral Law) is a faithful elucidation of divine rules for Jewish living that are obligatory upon all Jews today. Orthodox Judaism is more resistant than its liberal counterparts to the idea that biblical mandates can change in response to changing social circumstances.
In order to be considered Orthodox, a Jew must believe all laws given by God to Moses have value as written. All laws that can be followed, must be followed, and it is not for man to state that the intent of the law is different than the written law. To believe intent differs from the written word for even one law, is to be something other than Orthodox.
Vegans believe that all animals have the same rights to life and freedom as human beings, which is not what God has ever intended. God created man in His own image and no other animal has this distinction. We are unique and God has created this uniqueness, but vegans must lower man to something that is nothing more than just another animal.
God created us to be omnivores, which requires us to eat both plants and animals. Vegans must deprive their bodies of what God intended. There’s a belief they can get everything they need without eating any animal products, since plants have many of the substances we need. With a little research, they would realize the difficulty of our bodies extracting what we need from plants alone.
Bioavailability should be understood by anyone claiming to know how to improve on what God has designed. It is defined as the proportion of a drug or other substance which enters the circulation when introduced into the body and so is able to have an active effect. Other substance means what is eaten and plants do have a low bioavailability for humans.
The first brothers in the Bible are Cain and Abel. Cain was a farmer and Abel was a rancher. Both brothers made sacrifices to God, which would have meant Abel lawfully slaughtered animals. He had a burnt offering for God, which means he cooked the meat, and God favored Abel’s offering over Cain’s.
The earliest laws given are referred to as the Noahide Laws, and most are based on laws given to Adam. There are seven laws and two of the seven contradict what vegans believe. One is the prohibition against murder and the other is the prohibition against eating from the flesh of living animals.
Murder is defined as the unlawful killing of another human and does not extend to any other animal. When God prohibited murder as one of the first laws, it was regarding the taking of human life. God does not prohibit killing, which is completely different than murder.
The laws of Moses, which Orthodox Jews must follow, include several dietary aspects. No vegan can live by all the laws of God, since they violate them every time they do not eat what God has commanded. Any Jews who believes they can pick out only the laws they wish to follow cannot be Orthodox and there are other movements more fitting to putting yourselves above God.
Every justification given by vegans regarding being Orthodox are no different than the justifications given by other Jewish movements who do not follow all the laws. It always comes down to the belief that man knows better than God. It is God, not man, who has brought the laws and no man is superior to God in any way. To pick an choose the laws is the act of hubris and people should learn to humble themselves before God.
Vegans do not lift God up with anything they do. They have decided that God could not have made man in His own image, since they believe all animals, man included, are the same. They limit the uniqueness of man, which limits God.
Vegans have two distinct camps. The first is the worship of nature and the second is the denial of God. Neither are fitting for Jews and righteous gentiles alike. Both require the belief and worship of one God, and no vegan can truly claim to do this.
Vegans compare animals to man on a daily basis and worship at the altar of nature, rather than nature’s God. Jews are commanded to have no other gods besides God, which means the worship of nature is a violation of this commandment. You cannot be Orthodox and a vegan, since the two cannot coexist.
The vegans who do not worship nature are atheists who blindly accept Darwin’s Theory of Evolution. Man is nothing more than a slightly higher evolved primate and has no more importance than any other species. There is no God to worship and morality is subjective.
God commands man to be good stewards of the land, but never commands us to lower ourselves to the land. To be vegan is to do far worse than remove the uniqueness of man. It is to say God does not exist as one God.
