I'm going to argue with you a bit, not because I think Jesus was vegan but to sort of flesh out the issues involved. I hope that's ok.
Of course.
Its true that Jews did (do) eat meat for festivals, but did they ever eat meat for other purposes? Yes. They ate fish. Other than that? Mmm. I'm not sure, but I think so. Were (are) they and Jesus required to eat meat? It doesn't appear so except on certain occasions.
Yes that's true...Passover meant eating a roasted lamb as prescribed by law. All Israel was commanded to celebrate in this manner. (Num 9:9-12)
It seems they could have opted for a mostly vegetarian diet with interruptions. The poorer ones might not have had much choice I suppose, since meat was more expensive than grain. Jesus lived during his ministry fairly poor. He may have been mostly vegetarian except for at appointed times, due to the expense of meat. Some people may find that significant. I feel like it was just how things happened for him.
You are probably right about that. Jesus was born into a poor household, though not destitute. He was the firstborn in a large Jewish family and it would not have meant meat on the table at every meal....Solomon wrote in Proverbs 23:20-21....
"Do not be with heavy drinkers of wine, Or with gluttonous eaters of meat; For the heavy drinker and the glutton will come to poverty, And drowsiness will clothe one with rags."
So it appears that meat and wine were expensive.
In the wilderness, the Iraelites complained about their diet of manna. Exodus 16:2, 3....
"Then the entire assembly of the Israelites began to murmur against Moses and Aaron in the wilderness. The Israelites kept saying to them: “If only we had died by Jehovah’s hand in the land of Egypt while we were sitting by the pots of meat, while we were eating bread to satisfaction. Now you have brought us out into this wilderness to put this whole congregation to death by famine.”
God, on one occasion provided quail to satisfy their craving for meat, but they were impatient and fell to eating the unbled flesh. They were punished very severely.
But those in Israel who raised their own sheep and livestock would have included meat in their diet....there is certainly no prohibition on its consumption. But animals were valuable, so they were not consumed by the poor in any great quantity. Maybe just special occasions.
In the parable of the prodigal son, the father slaughtered the fattened calf (Luke 16) in celebration of his return.
It is interesting to note that prior to the flood, humans were vegetarians. But for some reason, God gave man permission to eat the flesh of other creatures.....he doesn't say why. (Gen 9:1-6)
The most extreme religious Jewish diet seems it did not exclude meat but instead excluded vine products like grapes.
Yes, there were specific roles of service to God (like the Nazarites)
There were three principal restrictions resting on those taking the Nazirite vow: (1) They were to drink no intoxicating beverage; neither were they to eat any product of the grapevine, whether unripe, ripe, or dried, nor drink any of its juice, whether in the fresh, fermented, or vinegar state. (2) They were not to cut the hair of their heads. (3) They were not to touch a dead body, even that of the closest relative—father, mother, brother, or sister.—
Num 6:1-7.
Jesus master, John the Baptist, ate locusts. The gospel says he ate locusts and honey, perhaps exclusively, both of which are insect derivatives. Most would not consider that a vegetarian diet but some might.
Since John lived away from much human contact in preparation for his role as herald (Luke 1:16, 17, 80) I think his diet was a reflection of his environment rather than his choice.
I don't believe that John saw himself as Jesus' master...quite the opposite in fact. (Matt 3:13-17) Jesus was the master.
There is no doubt that a diet without meat was man's first experience.....but there has to be a reason why God told man he could consume flesh after the flood. I wonder what was different in that world that was missing in the post flood environment? Man's lifespan dropped dramatically after that event, so we can only speculate as to why the added protein was necessary in their diet.
