Exit and Support has the following up:
We need to first understand that the observance of festivals in high demand groups is for the purpose of controlling members. It is much easier to have authority over someone if their lives are molded around the "church."
Leaders of totalistic groups have always taught that if healthy members didn't show up for the Passover service, they were gravely sinning and were in danger of "losing the Holy Spirit." To the contrary, the Scriptures show that the Holy Spirit and eternal life cannot be lost or taken away, and we are sealed the moment we place our faith and trust in Christ. (See John 14:16; John 10:28; II Corinthians 1:22; Ephesians 1:13; 4:30)
Christ, our Passover, has already been offered. Therefore, to continue to observe the O.T. Passover is to say He never came.
Today many Christians observe what is called the "Lord's Supper" (often referred to as Communion), but the issue is not whether we do or don't observe a ritual and how often. It is about what Christ has already done for us and remembering that every day. He no longer holds our sins against us.

What about The Night To Be Much Observed?
Should Christians celebrate the Night to be Much Observed? Nowhere does the Bible tell Christians to observe this occasion.
WHAT?!?!?!? How on earth can I say that? It's a Night. To. Be. Much. Observed. The Bible clearly tells us to remember it. It's in the name, for crying out loud.
How did Christ's original disciples spend the night after the Passover? Were they celebrating the night of this alleged observance, while their teacher's body lay in the garden tomb? It seems unlikely. There is no mention of a celebration that night, and John 20:11 tells us that Mary Magdalene was still weeping when she went to the tomb. The disciples appeared to be visibly upset when Christ met them on the road to Emmaus in Luke 24:17. Lavish food was the furthest thing from their minds.
In short, the case for celebrating Herbert W Armstrong's Night to Be Much Observed is flimsy at best. Christians who honestly consider its alleged timing and symbolism may find it a tad distasteful. The COGs have us celebrate Christ's victory when His body was barely cold in the grave, yet they ignore the miracle of His resurrection. If were commanded to keep it, that would be one thing. But we aren't. It isn't even in the Bible.
MUST CHRISTIANS OBSERVE THE OLD COVENANT PASSOVER?
Were gentiles in Corinth observing the Feast of Unleavened bread?
