His entire ministry, death, burial and resurrection was in accordance with every requirement of the Law. I do not question the fact that He entered the Holy of Holies. But I do question the timeframe you suggest. As I'm sure you know, the Temple here on earth is a replica of the one in Heaven (not only in form but also in law.) Since here on earth the Holy of Holies was entered only once a year on the Day of Atonement (Yom Kippur), I simply will not believe that Messiah would break His own rules and enter the Holy of Holies on the wrong day.
Think about this, the High Priest could only enter the Holy of Holies in the earthly tabernacle once a year. What was in the Holy of Holies? What did it represent? The throne of Almighty God. Who is Christ?
Joh 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
Joh 1:2 The same was in the beginning with God.
Joh 1:3 All things were made by him; and without him was not any thing made that was made.
Joh 1:14 And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
Now...
Joh 5:37 And the Father himself, which hath sent me, hath borne witness of me. Ye have neither heard his voice at any time, nor seen his shape.
Joh 6:46 Not that any man hath seen the Father, save he which is of God, he hath seen the Father.
So, who communed with Adam and Eve?
Gen 2:16 And the LORD God commanded the man, saying, Of every tree of the garden thou mayest freely eat:
Gen 2:17 But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.
Gen 2:18 And the LORD God said, It is not good that the man should be alone; I will make him an help meet for him.
Gen 2:19 And out of the ground the LORD God formed every beast of the field, and every fowl of the air; and brought them unto Adam to see what he would call them: and whatsoever Adam called every living creature, that was the name thereof.
Gen 2:20 And Adam gave names to all cattle, and to the fowl of the air, and to every beast of the field; but for Adam there was not found an help meet for him.
Gen 2:21 And the LORD God caused a deep sleep to fall upon Adam, and he slept: and he took one of his ribs, and closed up the flesh instead thereof;
Gen 2:22 And the rib, which the LORD God had taken from man, made he a woman, and brought her unto the man.
Gen 2:23 And Adam said, This is now bone of my bones, and flesh of my flesh: she shall be called Woman, because she was taken out of Man.
Gen 2:24 Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh.
Gen 2:25 And they were both naked, the man and his wife, and were not ashamed.
Who talked with Moses face to face...
Exo 33:11 And the LORD spake unto Moses face to face, as a man speaketh unto his friend. And he turned again into the camp: but his servant Joshua, the son of Nun, a young man, departed not out of the tabernacle.
Who did Moses see...
Exo 33:18 And he said, I beseech thee, shew me thy glory.
Exo 33:19 And he said, I will make all my goodness pass before thee, and I will proclaim the name of the LORD before thee; and will be gracious to whom I will be gracious, and will shew mercy on whom I will shew mercy.
Exo 33:20 And he said, Thou canst not see my face: for there shall no man see me, and live.
Exo 33:21 And the LORD said, Behold, there is a place by me, and thou shalt stand upon a rock:
Exo 33:22 And it shall come to pass, while my glory passeth by, that I will put thee in a clift of the rock, and will cover thee with my hand while I pass by:
Exo 33:23 And I will take away mine hand, and thou shalt see my back parts: but my face shall not be seen.
Why, it was the one who became Jesus Christ. Jesus Christ was the one in the Old Testament known as YHVH, LORD or maybe a little more accurately The Eternal, since that is what is meant here. Anyhoo, at His death (and He really did die) what happened to the veil in the Temple?
Mat 27:51 And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent;
so that the Holy of Holies was exposed. Where did Christ go?
Rev 3:21 To him that overcometh will I grant to sit with me in my throne, even as I also overcame, and am set down with my Father in his throne.
He went into the Holy of Holies in Heaven and sat down beside the Father (where He had been in the past) and this was on the Wave Sheaf offering not on the Day of Atonement.
Although it involves His sacrifice...
Lev 16:9 And Aaron shall bring the goat upon which the LORD'S lot fell, and offer him for a sin offering.
Lev 16:15 Then shall he kill the goat of the sin offering, that is for the people, and bring his blood within the vail, and do with that blood as he did with the blood of the bullock, and sprinkle it upon the mercy seat, and before the mercy seat:
Lev 16:16 And he shall make an atonement for the holy place, because of the uncleanness of the children of Israel, and because of their transgressions in all their sins: and so shall he do for the tabernacle of the congregation, that remaineth among them in the midst of their uncleanness.
Lev 16:17 And there shall be no man in the tabernacle of the congregation when he goeth in to make an atonement in the holy place, until he come out, and have made an atonement for himself, and for his household, and for all the congregation of Israel.
Lev 16:18 And he shall go out unto the altar that is before the LORD, and make an atonement for it; and shall take of the blood of the bullock, and of the blood of the goat, and put it upon the horns of the altar round about.
Lev 16:19 And he shall sprinkle of the blood upon it with his finger seven times, and cleanse it, and hallow it from the uncleanness of the children of Israel.
Atonement pictures something else. It is part of the fall harvest Feast Days. It pictures the world being made AT ONE with God at the return of Christ. It also pictures this event in Rev 20...
Rev 20:1 And I saw an angel come down from heaven, having the key of the bottomless pit and a great chain in his hand.
Rev 20:2 And he laid hold on the dragon, that old serpent, which is the Devil, and Satan, and bound him a thousand years,
Rev 20:3 And cast him into the bottomless pit, and shut him up, and set a seal upon him, that he should deceive the nations no more, till the thousand years should be fulfilled: and after that he must be loosed a little season.
Lev 16:10 But the goat, on which the lot fell to be the scapegoat, shall be presented alive before the LORD, to make an atonement with him, and to let him go for a scapegoat into the wilderness.
Lev 16:20 And when he hath made an end of reconciling the holy place, and the tabernacle of the congregation, and the altar, he shall bring the live goat:
Lev 16:21 And Aaron shall lay both his hands upon the head of the live goat, and confess over him all the iniquities of the children of Israel, and all their transgressions in all their sins, putting them upon the head of the goat, and shall send him away by the hand of a fit man into the wilderness:
Lev 16:22 And the goat shall bear upon him all their iniquities unto a land not inhabited: and he shall let go the goat in the wilderness.
Finally, the real culprit in sin and misery will have the full responsibility laid on his head and he will bear it. This does not excuse our sin or our responsibility, but it identifies and punishes the prime mover.
