Look, you can keep repeating your theory but it does NOT match scripture nor historical accounts.
It is not a theory. That's what you don't seem to grasp. What I have shared
IS the scripture, and
IS the historical account. But since it doesn't seem to be sinking in for you, let me instead give you a version of what I've been saying made from direct scripture, with no paraphrasing on my part.
And the first day of unleavened bread, when they killed the passover (Mark 14:12; cf. Luke 22:7), his disciples said unto him, Where wilt thou that we go and prepare that thou mayest eat the passover? (Mark 14:12; cf. Matthew 26:17, Luke 22:7-9) And he sendeth forth two of his disciples (Mark 14:13), Peter and John, saying, Go and prepare us the passover, that we may eat (Luke 22:8). Behold, when ye are entered into the city, there shall a man meet you, bearing a pitcher of water; follow him into the house where he entereth in. And ye shall say unto the goodman of the house (Luke 22:11 cf. Mark 14:14), The Master saith unto thee (Matthew 26:18, Mark 14:14, Luke 22:11), My time is at hand; I will keep the passover at thy house with my disciples (Matthew 26:18). Where is the guestchamber, where I shall eat the passover with my disciples (Luke 22:10-11; cf. Mark 14:14)? And he will show you a large upper room furnished and prepared: there make ready for us (Mark 14:15; cf. Luke 22:12). And his disciples went forth, and came into the city, and found as he had said unto them: and they made ready the passover (Mark 14:16; cf. Luke 22:13, Matthew 26:19). And in the evening (Mark 14:17), when the hour was come (Luke 22:14), he cometh with the twelve (Mark 14:17), and sat down with the [...] apostles (Luke 22:14, Matthew 26:20). And he said unto them, With desire I have desired to eat this passover with you before I suffer (Luke 22:14). And as they did eat, he said, Verily I say unto you, that one of you shall betray me (Matthew 26:21; Mark 14:18, Luke 22:21).
Concerning "And the first day of unleavened bread, when they killed the passover (Mark 14:12; cf. Luke 22:7)":
Speak ye unto all the congregation of Israel, saying, In the tenth day of this month they shall take to them every man a lamb, according to the house of their fathers, a lamb for an house [...] And ye shall keep it up until the fourteenth day of the same month: and the whole assembly of the congregation of Israel shall kill it in the evening. In the first month, on the fourteenth day of the month at even, ye shall eat unleavened bread, until the one and twentieth day of the month at even. (Exodus 12:3, 6, 18).
Concerning the time of day:
Mishnah: The [afternoon] Tamid is slaughtered at eight and a half hours and is offered at nine and a half hours. On the eve of passover it is slaughtered at seven and a half hours and offered at eight and a half hours, whether it is a weekday or the sabbath. If the eve of passover fell, on sabbath eve [Friday], it is slaughtered at six and a half hours and offered at seven and a half hours, and the passover offering after it (Tal. Pesachim 58a; cf. Yoma 28b).
So these high priests, upon the coming of that feast which is called the Passover, when they slay their sacrifices, from the ninth hour till the eleventh, but so that a company not less than ten belong to every sacrifice, (for it is not lawful for them to feast singly by themselves), and many of us are twenty in a company [...] (Joseph BJ 6.423).
If Yeshua dies on the 15th as you say, and Yom HaBikkurim was on the 16th, He would have been in the tomb only over 1 night if that! Do you really expect anyone to buy into that? We know for a fact you are wrong because we have testimony on the correct chronology of the events from the eyewitnesses on the road to Emmaus! You have no leg to stand on...you have sooooo many holes in your theory it looks like swiss cheese.
And this nonsense here is the other thing I've been saying. I show you scripture, and you argue with your theology. I give you facts, and you counter with your misguided reasoning.
The disciples on the road to Emmaus have no bearing on this conversation. I do not deny that Jesus died on a Friday, or that he rose on a Sunday. He was in the grave during the three days of Friday, Saturday, and Sunday. The scriptures attest to a Friday crucifixion (Mark 15:42, Luke 23:54, Matthew 27:62), and a Sunday resurrection (Mark 16:9), and corroborate the span of three days (Luke 24:13-21). Three days and nights, whether full or partial, are being expressed synecdochically, and I don't rightly care if the reality of this fits within your theological bubble.
So stop responding to me if you can't accept the scriptures. My conclusions aren't going to change, because what I'm saying is verbatim from the scriptures themselves. Why you can't see that is beyond me.
