One of the primary reasons God in the Old Testament demanded sacrifices of animals is to prove a point. Most pagan religions, particularly the Egyptian one, either revered animals or were part animal in their visualization of their demon gods.
Christians will slaughter every cow in India one day and have beef tacos when they convert from demon worship.
And again. Neither scripture nor tradition supports your claim.
Are you part of one of these weird denomination where every random person can interpret the bible to their liking?
I gave you two scriptural references, and a passage of the Summa Theologica. You ignored both.
Are you a Protestant?
If you are a Catholic, find me any traditional opinion or quote from the Catechism that supports your claim.
What you posted does not support your claim.
Oh, it most certainly does, and besides, I provided the relevant passage from the Summa Theologica, which is 2nd most Catholic of Catholic books (the first being the Bible) Here's the quote in particular:
"Of birds they were allowed to eat the tamer kinds, such as hens, partridges, and the like. Another reason was detestation of idolatry: because the Gentiles, and especially the Egyptians, among whom they had grown up, offered up these forbidden animals to their idols, or employed them for the purpose of sorcery: whereas they did not eat those animals which the Jews were allowed to eat, but worshipped them as gods, or abstained, for some other motive, from eating them, as stated above (A[3], ad 2). The third reason was to prevent excessive care about food: wherefore they were allowed to eat those animals which could be procured easily and promptly."
Are you Protestant?
Looks like you're afraid to answer the question. You could just take the loss and not reply, which I think would be better for you at this point.
