Jesus was buried on the same day as he died. He had to be buried the same day or else Joseph and Nicodemus would have violated the Sabbath if they buried him after sunset. John 19:38-42 makes this clear, he was hastily buried so as to avoid violating the Sabbath.
so if Jesus died on the 14th of Aviv, that is day one. you can’t ignore the day he died when counting days, that has to be your starting point.
verses from the Gospels supporting one sabbath:
Matthew 28:1
Mark 15:42
Luke 23:54-56
John 19:31
i would ask for verses supporting two sabbaths that week, but since i know there aren’t any, i won’t bother.
This doesn't in anyway indicate there was only one Sabbath that week. It does provide a clue for later.
Mark 15:42 It was Preparation Day (that is, the day before the Sabbath). So as evening approached...
Preparation Day is the day prior to a High Sabbath day such as Passover. There are no "preparation days" for regular Sabbaths (i.e., the 7th day of the week.
Luke 23:54-5654 It was Preparation Day, and the Sabbath was about to begin.
55 The women who had come with Jesus from Galilee followed Joseph and saw the tomb and how his body was laid in it. 56 Then they went home and prepared spices and perfumes. But they rested on the Sabbath in obedience to the commandment.
Nothing helpful here in ruling out that there were two Sabbaths that week (same as above).
John 19:31 Now it was the day of Preparation, and the next day was to be a special Sabbath. Because the Jewish leaders did not want the bodies left on the crosses during the Sabbath, they asked Pilate to have the legs broken and the bodies taken down.
Same here. So your claim that "all four Gospels only indicate one Sabbath day", is false.
Here is the timeline:
Yeshua was crucified and died on the day of preparation (Wednesday) for Passover, at exactly the same time the lambs were sacrificed.
The next day, the day after the preparation day (Passover - Thursday), guards were posted and the tomb was sealed. (Matt. 27:62-64)
[The women] prepared spices and ointments; and rested the Sabbath day according to the commandment (This was Passover also, as above). Luke 23:56
The Tomb was sealed and guarded, therefore the women could not have anointed the body Friday and that evening began the next Sabbath (Saturday), even if the tomb had not been sealed and guarded. Btw, the seal was an iron rod driven through a hole in both the stone (which was rolled into place) and the rock wall behind it, and then held in place by having molten lead poured in around it.
Luke 24 Now upon the first day of the week, very early in the morning, they came unto the sepulchre, bringing the spices which they had prepared, and certain others with them.
2 And they found the stone rolled away from the sepulchre.
3 And they entered in, and found not the body of the Lord Jesus.
And you know the rest...
Only a Devine hand could have foretold and caused these events to play out EXACTLY as prophesied - to the very day, the very hour, and the very moment. The Truth is far more breathtaking than the lies we've inherited in the west.
