The new light is a bit of give and take by the GB. They have taken upon themselves the title of the faithful and discreet slave, in exchange for pushing the 'appointment over all of his [christ's] belongings' out into the future, and also in exchange for allowing the earthly class to be counted as 'domestics'. The GB can now totally lord it as kings over the flock in exchange for having "dignified" them by including them as domestics. No wonder the GB member said that they "love this idea"! Very clever of them.
What may backfire for the GB though is a realisation by a growing number of JW's that although they are now included in the 'domestics', should they not also now be included in the 'new covenant'? This could lead to more JW's partaking at the memorial than ever before.
Its rather obvious in scripture that the new covenant is only about forgiveness of sins by Christ's shed blood, its really nothing to do with destination, whether your hope is to live forever in heaven or earth. "For there are a new heavens and a new earth, in which righteousness is to dwell". They are all equally righteous in God's eyes, so they should all be counted as in the new covenant. All Christians in scripture partook of the emblems and were in the new covenant. Only through Judge Rutherford's mysticism was this scriptural truth changed in the 1930's.
The "great crowd" are said to be standing in the naos itself in Revelation 7, the inner temple, which the Society now admits. And they are dressed in white robes, having been washed of their sins in the blood of the lamb. All of this must surely mean that the future great crowd are also in the new covenant. They could not possibly be in such a holy state before God unless they are in the new covenant. How can they possibly avoid Adamic death and pass through the great tribulation unless they are in the new covenant?
By including the 'other sheep' as domestics in Christ's household, the Society should really should take the next step and admit that those of an earthly class, who have also put their faith in Christ's shed blood for forgiveness of their sins, are also in the new covenant and can partake at the memorial.
What this means is that the number of partakers may increase even more in years to come, not drop off as the GB would hope. More of the 'other sheep' will feel worthy of partaking now that they are counted as one of the 'domestics' in the master's household, despite feeling they do not have a 'heavenly hope'.
If I am right on that, what this may all be leading up to eventually is further 'new light' that the 'other sheep' can partake of the emblems at the memorial as well, also being counted as in the new covenant.
