I said (in reference to the meal of the Last Supper) "The synpotic Gospels are clear it was the Passover. The church fathers agree."
You did not disagree with that, but say it's a Chabura meal, not a seder meal. That is contradictory. A Chabura meal has nothing to do with Passover. The seder meal is celebrated the first night of Passover.
The synoptic Gospels and the church fathers are clear -- the Last Supper was the celebration of the Passover. That makes it a seder meal.
What is served -- bitter herbs, roasted lamb, bread, wine, and other stuff I'd have to go look up.
You seem to be struggling with the difference identified between the synoptic Gospels and John's Gospel. The synoptics have the Passover being celebrated at the Last Supper; John's Gospel has the lambs being sacrificed while Jesus is on the cross for the Passover to be celebrated that night. That's long been pointed to by non-believers as a "contradiction" in Scripture.
The resolution to that is understanding that there was conflict among the Jews about the official night to begin Passover. This site speaks of it in this way: "On the first night of Pesach (first
two nights for traditional Jews outside
Israel), we have a special family meal filled with ritual to remind us of the significance of the holiday. This meal is called a seder
, from a Hebrew
root word meaning "order," because there is a specific set of information that must be discussed in a specific order. It is the same root from which we derive the word "siddur"
, (prayer book). An overview of a traditional seder is included
below."

If you pop up the little "two nights" link on the site, it says that "An extra day is often added to holidays because in ancient times, there was doubt at to which was the correct day".
Here's another article that mentions the 'two passovers'.

John's timing does not supercede what all the other Gospels say about the meal itself -- they were eating the Passover. That means seder.
