I was having a friendly discussion with a Jewish person about the Scriptures. He took issue with some of the verses in the book of Hebrews, chiefly this verse (bracketed inclusions and italics my own):
...but He [[that is, Christ]], having offered one sacrifice for sins for all time, sᴀᴛ ᴅᴏᴡɴ ᴀᴛ ᴛʜᴇ ʀɪɢʜᴛ ʜᴀɴᴅ ᴏғ Gᴏᴅ...
-Hebrews 10:12 (NASB1995)
He said that such a single sacrifice for sin was impossible, for the Prophets had said that animal sacrifice would continue forever. He then directed me to the following verses from the Prophets:
“All the flocks of Kedar will be gathered together to you,
The rams of Nebaioth will minister to you;
They will go up on with acceptance on My altar,
And I shall glorify My glorious house."
-Isaiah 60:7 (NASB1995)
"... and the Levitical priests shall never lack a man before Me to offer burnt offerings, to burn grain offering and to prepare sacrifices continually."
-Jeremiah 33:18 (NASB1995)
"It shall be the prince’s part to provide the burnt offerings, the grain offerings and the drink offerings, at the feasts, on the new moons and on the sabbaths, at all the appointed feasts of the house of Israel; he shall provide the sin offering, the grain offering, the burnt offering and the peace offerings, to make atonement for the house of Israel... In the first month, on the fourteenth day of the month, you shall have the Passover, a feast of seven days; unleavened bread shall be eaten. On that day the prince shall provide for himself and all the people of the land a bull for a sin offering."
-Ezekiel 45:17,21-22 (NASB1995)
The first seems to imply that the flocks/rams will be offered on God's altar in the future, the second seems to imply a continued Levitical priesthood with offerings, and the third seems to imply that all the Levitical offerings (including sin offerings!) will be celebrated in the future, as well as Passover!
I was quite stumped, then, for we (of course) hold that in the eternal state, no sacrifices will be made. The only answer I could find was from a premillenalist perspective, which held that memorial animal sacrifices would be made in the Millennial Kingdom. However, a thousand years is hardly "forever."
So, here is my question: how do Catholics reconcile these Scriptures with our conception of the World to Come?
