And just WHAT were they eating?
Are you looking for legalism there Elsie? The point is that the Lords Supper was instituted during a meal that the Apostles were having. It happened to be the Passover meal but no indication is given that it has to be at Passover. In Corinthians Paul indicates that the Lords Supper was eaten during a meal but that they were separating themselves in cliques or according to divides of rich and poor etc. He indicates that in a gathering of Christians there should be no separation of classes. All are to come together.
All references of partaking of the Lords Supper in scripture are during a common meal. The person condemned is not the person who does not discern that the elements he takes in his hands are the Lord's body. The person condemned is the person who does not discern that Christians are the Lord's body, and must be in unity before they dare approach the sacrament.
