The issue seems to be how "they understood" these things.
Who is the "They", Mary and the Disciples who clearly understood the Sabbath Jesus was "Lord of", or the mainstream preachers of that time who had polluted God's sabbath, and were teaching for doctrines the commandments of men?
The 1st day of unleavened bread as a 24 hour period was from the evening of the 14thy day until the evening of the 15th day of the calender month
Yes, Passover was "Preparation Day" for the First Day of Unleavened Bread. That is why it was important, to fulfill all Righteousness, that Jesus was placed in the grave before sundown, the end of Passover.
How did "who" do "what"?
How are you counting days, how did they count days during the festivals?
They would have followed God's Instruction in the Torah.
A friday according to a Roman day?
The day God created is 24 hours. There are 7 days in a week, according to the God "of the bible". Romans didn't create the "DAY" God did.
"
And the evening and the morning were the first day". Each day has a "day" and a "night", and starts with the Night. I'm not sure why you would imply that the day and night Jesus referred to was a "Roman Day".
Actually Judaism counts days according to the sacrifices offered on those days.
What exactly is "Judaism" in your religion? Was it living by the Spiritual Word of God as Jesus and the examples of Faithful men given us in scriptures did? Or is "Judaism" the "Jews religion" that taught for doctrines the commandments of men, not God, polluted God's Sabbaths, and persecuted the Church of God?.
You need to define the context of your use of this world, before we can have a honest discussion about it.
Which sacrifices go from morning to Evening.
Of course they did, sacrifices were made in the day, not the night. By definition, morning comes after night. Darkness dwelled on the earth, before Light. Darkness first, then Light. ignorance first, and then wisdom. 6 days of work first, then Rest.
I'm OK with that.
A day according to temple or liturgical time: DAILY SACRIFICES (day by day)
Look, I understand how important religious traditions are, and how far men will go to defend and preserve them. I know there is no Biblical instruction to turn away from God's Sabbath, to the Catholic Sabbath. I know that God knew the Day the Prophesied Messiah would be raised from the dead, from the foundation of the World.
I also know from experience, that "many", who call Jesus Lord, Lord, will never turn away from their religious traditions, which is shown to me in the scriptures over and over and over and over and over.
I am happy to discuss with you the spiritual meaning of the daily sacrifices, "made by fire" etc., in a different thread. But this thread is about God's sabbaths. let's stay focused on that.
The days of the feasts were morn to evening day to day. A liturgical day.
In your religion, this might be true. But according to Moses and the Prophets, the Feast Day begins at evening.
Jesus ate the Last supper with His Disciples after sundown on the 13th of Nisan, which would be the 14th of Nisan. After the Passover meal, Jesus
went to
Gethsemane, and prayed, "at night" before the morning of Passover. In the morning HE was betrayed by Judas, tried, beaten stripped and crucified, all in the same day, Passover, which had begun the night before. And He was placed in the Grave "Before" the High Sabbath of the First day of Unleavened bread.
So it's right there in your own Bible.
Read the story of the Passover in Moses Time.
Ex. 12:
9 Eat not of it raw, nor sodden at all with water, but roast with fire; his head with his legs, and with the purtenance thereof. 10 And ye shall let nothing of it remain "until the morning"; and that which remaineth of it until the morning ye shall burn with fire.
Passover begins at sundown, at least according to the Holy scriptures.
Judaism actually considers the whole night of Passover to be an extension of the 14th day (15th by calendar date), because the sacrifice of the day were not to be left over until the morning.
Personally, I don't know what you mean by "Judaism". I understand Passover by reason of use. Not really interest in the Talmud, or the Jews religion, nor the Catholic religion and her Protestant daughters religious traditions and philosophies. I'm more interested in what the Scriptures actually teach and how they help me to "know the One True God" that Jesus wants me to know.
