Was the "Last Supper" a Seder?

This is how I understand it.  Towards the end of the 13^th day part, right before sunset, that start of the 14^th of Nisan, is when the lamb was killed at the Temple for Jesus and the disciples to observe the Passover (Seder) meal.  We know the Israelites had to be in their homes before sunset or start of the 14^th or the death angel will come to them, then the lamb had to be killed right before sunset on the 13th.  We know that the Passover meal or Seder is the same thing.  Let’s look at two basic facts.  Paul tells us “Jesus, on the night he was betrayed, took bread” and then wine and said “it is not the Lord's Supper you eat.”  During the Seder or last supper meal, Jesus instituted and commands three new service for the church today, a footwashing service and the bread and wine service during the Seder.  This was the 3^rd cup, redemption /  blessing cup.  The 4^th cup will not be had until the Marriage Supper.  John tells us that supper being ended, Judas then betray Jesus.  Remember, when Jesus sets up His Kingdom during the millennium, all people will then celebrate the Passover on the evening of the 14^th according to Ezekiel. Blessing

John 13:2 - And supper being ended, the devil having now put into the heart of Judas Iscariot, Simon's son, to betray him;

John 13:4-5 - so he (Jesus) got up from the meal, took off his outer clothing, and wrapped a towel around his waist.  After that, he poured water into a basin and began to wash his disciples' feet, drying them with the towel that was wrapped around him.

John 13:14-15- Now that I, your Lord and Teacher, have washed your feet, you also should wash one another's feet. I have set you an example that you should do as I have done for you.

Luke 22:19- And he took bread, gave thanks and broke it, and gave it to them, saying, "This is my body given for you; do this in remembrance of me."

1 Cor 11:20-23 - When you come together, it is not the Lord's Supper you eat, for as you eat, each of you goes ahead without waiting for anybody else. One remains hungry, another gets drunk. Don't you have homes to eat and drink in? Or do you despise the church of God and humiliate those who have nothing? What shall I say to you? Shall I praise you for this? Certainly not! For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread,

Ezek 45:21-  "'In the first month on the fourteenth day you are to observe the Passover, a feast lasting seven days, during which you shall eat bread made without yeast.
