The passage referred to speaks specifically of Sabbath to Sabbath, and your explanation is that it doesn't mean the Sabbath is significant for that, and it is dismissed with it said that is only an expression, when you don't seem to have basis for that, Jesus still spoke for Sabbath meant for man, so it is significant in that passage.
I have to say I don't get the reference to Ellen, I don't know anything about that. But who is talking about Heaven in this discussion? Are you confusing what there is of eternity with what happens with Christ's return to this world? The distinction is left, with the expression in those passages, "just as the new heavens and the new earth I make will endure" for comparison to the enduring of "your offspring and your name".
Scripture is asked for regarding the commandments? Nothing is being made up, here there is such accusations again. The scripture just used from Isaiah 66 is still good for that, not to mention other passages from Isaiah, such as Isaiah 56:6, and passages from other old testament scriptures as well. There still is Jesus speaking to commandments shown in Matthew 5:18-19.
Saying gentiles won't be required to be Jews has nothing to do with you not wanting to be there otherwise, I have the basis for saying it from passages such as Acts 15:19.
Jesus was never a horrible person and I am never suggesting he was. There is though no great basis to say he was eating meat, other than interpretation that isn't certain. The perfection of Yahweh from the beginning in the creation did not have animal meat given to mankind as food. Meat for food is not part of perfection. It was permitted for food thousands of years afterward, after the global flood, and Noah's sacrifice to Yahweh, when there wasn't the abundant growth of vegetation for food, and meat mentioned since then is identified with sacrifice, which is in typifying Christ dying on our behalf, and such is fulfilled, animals don't have to die for us now. In that permission that had been given, which never was a requirement, any blood was never to be had with it, but this gets disregarded. Human desire and obsession has killing of animals continue, but this is not a virtue. It is not healthy to keep having meat, or even animal products, which I can show abundantly, with there being health problems that come from that which can be reversed with avoiding the animal products, and processed foods. It has great abuse to animals by many billions every year, it also takes up a great great deal more resources, and people are starving, and some dying, from that. There is a huge impact with harm to environments from it, and there is more emissions of greenhouse gases contributing to global warming from it. It won't always continue, scriptures show that, and it won't continue while Jesus is here when he returns.
Even while Sabbath would be a shadow, it has nothing said anywhere that Sabbaths won't continue, and when Yahweh made it holy, why wouldn't it continue? But indeed Jesus is the reality, and the rest of Sabbath, with coming to God, doesn't have reality, as always, without Jesus Christ. What is said is that none of us should judge others of us regarding these things.
