As Yesidid mentioned, the followers of the WTS may not celebrate the resurrection of Christ, although they do claim to believe in it.
However there is a problem with this claim. A claim that is merely superficial and cannot be sustained by a close scutinty of WT theology. What exactly do the WT followers believe about the resurrection of Christ?
Their fundamental belief is that death is a biological finality that results in the total cessation of a person's being. In other words, a person at death is then reduced to nothing, a void. As complete a void as if that person had never existed.
So, when Jesus died, He too was reduced to oblivion, a condition in which He no longer existed in any form whatsoever. Oblivion, nothingness, void, empty non-existence cannot be "resurrected" You can only resurrect a person if that person has his/her individuality preserved somewhere, and in some form. When you die the Bible assures you that you, as a unique individual that will never be duplicated in the course of eternity, will be resurrected.
This is not the WT promise. Their belief entails the notion of "recreation" not resurrection. According to WT theology, when a person dies, the impersonal memory of that person is preserved with God, so that, when the time comes, that person is recreated by the creation of another being into which the memory banks of the original are then introduced. This means that the recreated individual is not the same person who has died, since that original no longer exists, but is a clone.
The same is the case with Jesus. When He died, He went into the WT state of non-existence. But His memory was preserved, and this memory was implanted in another being recreated for the purpose. A Jesus Mk 2, as it were. This Jesus Mk 2, evidently prancing about in heaven and communicating sacred secrets to His loyal associates already there, is not the Jesus who died for you and me. That Jesus, according to WT theology is finished and discarded with, like an old shoe. The Jesus Mk 2, which has done nothing to merit it, will now live for the rest of all existence, being endowed with immortality.
Probably without personally realizing it, the average R&F WT follower is in fact celebrating the passing into oblivion of a unique individual who no longer exists.
Incidently, nowhere did Jesus command His followers to celebrate His death. He commanded His followers to "do this" - that is, the Last Supper. The significance of this was not to celebrate His death, but to proclaim it. We will do this, not in celebration of His death, but in anticipation of His Coming again [1Cor 11:26]
This is not to say that the death of Jesus is unimportant. God fordid, because we as believers proclaim His death. His death brought about the rconcilliation of an estranged humanity with Deity. We can now have access to God, thanks to the death of Christ.
But the richness of spiritual truth, of infinite joy, of celebration, in fact is the theological importance and the implications of, the Resurrection of Jesus. It is the Resurrection of Christ, not His death which releases a new power for Christian living.[Phil 3:10]
It was the Resurrection, not the death of Jesus, that empowered early Christians to testify to their beliefs with a message that was worth taking to the ends of the earth.
It is the believers hope still. Because Jesus Himself [and not some clone] was resurrected, we can rest assured that so will we. Now that is something worth celebrating.
