A lot more can be said to highlight the falsity of the Society's teachings on who can partake of the emblems, who is in the new covenant, etc in this article. (You seem a bit tired lately Blondie). Where do you start on such a big topic? Heres a few points:
14."God saw good for all fullness to dwell in him [Christ], and through him to reconcile again to himself all other things by making peace through the blood he shed on the torture stake, no matter whether they are the things upon the earth or the things in the heavens." -Col. 1:19, 20.
Paul here says Jesus blood is the means for reconciliation regardless of whether it's something in heaven or on earth. If the means for the 'great crowd' to pass into a new earth is by forgivenss of their sins (which is the meaning of the new covenant) by Christ's shed blood then clearly they should partake at the memorial?
15. "The things in the heavens" that are reconciled to Jehovah by means of Christ's shed blood are the anointed Christians, called to reign with Christ in the heavens. Christians who are "partakers of the heavenly calling" are declared "righteous for life." (Heb. 3:1; Rom. 5:1. 18) Jehovah then begets them as spiritual sons. The holy spirit bears witness to them that they are "joint heirs with Christ." called to become kings and priests in his heavenly Kingdom. (Rom. 8:15-17; Rev. 5: 9, 10) They become part of spiritual Israel, "the Israel of God," and they are taken into the "new covenant." (Jer. 31:31-34; Gal. 6:16) As members of the new covenant, they are entitled to partake of the Memorial emblems, including the cup of red wine, of which Jesus stated: "This cup means the new covenant by virtue of my blood, which is to be poured out in your behalf." --Luke 22:20.
But Jesus created two covenants: the "new covenant" and the "covenant for a Kingdom'. Where did Jesus say that the "new covenant" is anything to do with reigning with him in the heavens? Jesus only said this in relation to the "covenant for a Kingdom". This is a classic example of the Watchtower conflating both covenants to mean the same thing: only about ruling as kings in heaven. The new covenant is about forgiveness of sins and it applies to everyone who has faith in Jesus shed blood for forgiveness of their sins, irrespective of whether they feel a heavenly or earthly calling.
16. "The things upon the earth" are Christ's other sheep who have the hope of living forever on earth. To these also Jehovah's chosen Servant brings a righteous standing before Jehovah. Because they have faith in Christ's ransom sacrifice and thus "have washed their robes and made them white in the blood of the Lamb," Jehovah declares them righteous, not as spiritual sons, but as his friends, giving them the wonderful prospect of surviving "the great tribulation." (Rev. 7:9, 10, 14; Jas. 2:23) Not being in the new covenant and therefore not having the hope of living in heaven, these other sheep do not partake of the Memorial emblems but attend as respectful observers.
But hold on a minute, the "other sheep" have NOT YET "washed their robes and made them white in the blood of the Lamb" because they great crowd is a FUTURE class, which the Society now admits. And in a 2000 QFR the Watchtower Society finally also admitted that the great crowd stands in the temple itself, the 'naos', not one of the outer courtyards. Rev 7 says the great crowd is "rendering sacred service" in the naos. Is it reasonable to think that the great crowd are sanctified enough to be described as standing in the temple itself rendering sacred service having been washed in the blood of the Lamb yet they are not in the new covenant and are thus not permitted to partake of the emblems? It's absurd and contradictory reasoning which is obviously false.
And who would the first century Christians have understood the "other sheep" to be? Who was Jesus talking to when he uttered John 10:16? Do you suppose first and second century Christians interpreted this to mean Jesus was prophesying about an unknown religious group who would have an earthly hope millinnia into the future, or do you think they would have realised that that Jesus was here talking about non-Jewish sheep who would be added to the Christian fold when Peter used the keys of the kingdom?
If you are a lurking JW who does not have a "heavenly hope" you should still partake of the emblems if you believe Jesus is your saviour and his blood acts for forgiveness of your sins.
