Some people believe that it was when Christ died, yes. And the Church, but is the new covenant only good effectual or begun for us?
What is being completely ignored is that not all animal sacrifices had been to atone for man's sin.
In other words, you are dealing with a long held tradition of ignorance on this.
Their books based learned response is that Christ's sacrifice for man's sin replaced all Israel's sacrifices.
But as I have shown, Israel had all sorts of sacrifices that had nothing to do with man's sin, rather, with the fact that this world itself is fallen /tainted with sin, and will continue to remain falleb during Christ's Millennial Reign, and Israel will still be in a fallen physical body, as those in Early Acts had been, and so, Israel's various EXTERNAL cleansing and atoning rituals will STILL be in force.
Reread my post - THIS is what I was talking about.
What did I get in return from those who supposedly understood my post - passages from Hebrews, and so on, about the very opposite of what I was talking about.
Why?
Because theirs is the traditional view parroted in their endless books written by "Reformed" writers parroting what they themselves learned in previous books by "Reformed" writers, against the obvious in Scripture about Israel's Prophesied future.
You see this here...
Romans 11:25 For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in. 11:26 And so all Israel shall be saved: as it is written, There shall come out of Sion the Deliverer, and shall turn away ungodliness from Jacob: 11:27 For this is my covenant unto them, when I shall take away their sins.
Not only is that yet future, but they will still be in a fallen physical body, and on a fallen physical Earth, prior to the Last and Final rebellion, at the end of a Thousand Years, followed by the Great White Throne Judgement, followed by The New Heaven and New Earth, at last...
Revelation 20:7 And when the thousand years are expired, Satan shall be loosed out of his prison, 20:8 And shall go out to deceive the nations which are in the four quarters of the earth, Gog, and Magog, to gather them together to battle: the number of whom is as the sand of the sea. 20:9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them. 20:10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet are, and shall be tormented day and night for ever and ever. 20:11 And I saw a great white throne, and him that sat on it, from whose face the earth and the heaven fled away; and there was found no place for them. 20:12 And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works. 20:13 And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works. 20:14 And death and hell were cast into the lake of fire. This is the second death. 20:15 And whosoever was not found written in the book of life was cast into the lake of fire.
1 Corinthians 15:24 Then cometh the end, when he shall have delivered up the kingdom to God, even the Father; when he shall have put down all rule and all authority and power.
His Millennial Reign is towards that purpose..
15:25 For he must reign, till he hath put all enemies under his feet. 15:26 The last enemy that shall be destroyed is death. 15:27 For he hath put all things under his feet. But when he saith all things are put under him, it is manifest that he is excepted, which did put all things under him.
The end of all that being...
15:28 And when all things shall be subdued unto him, then shall the Son also himself be subject unto him that put all things under him, that God may be all in all.
Read that in line with rereading my previous post on the intent of those other animal sacrifices - that we're not focused on atoning for man's sin...
Acts 17:11, 12.
