They do this to hold on to 1914, and the power that doctrine gives them (They are the faithful slave, appointed by the returned Christ). They likely base it upon 1Cor.11:26, that states that we hold the Memorial until the arrival of Christ. Online writings exposed the unreasonableness of Claiming Christ arrived 100 years ago, and yet the Memorial continues to be observed.
First, it was "stop counting partakers"...then it was "there is no faithful slaves except the GB"....Now it is, there's no faithful slave at all.
WHY? This all fulfills prophecy. Dan.12:7 reads: "...when the power of the Holy Ones has been completely shattered; all these things shall be finished." It's time to rid the Beast of the Harlot who rides it. Every detail in Revelation is in plain sight, but it needs to be seen spiritually. (Rev.11:1,2; Matt.24:15).
So when people here were wondering why there were two groups of people on the Memorial invitation, the upper group are all dead now. They are now referred to as the 144000. Only problem for the WT now is....
Jesus said that the anointed generation would "by no means pass away" until ALL things occur.....including the new world...where the dead are resurrected and all maladies are healed and we live forever.
I wonder what the next BS will be.
