The scriptures are omitted for the sake of brevity. Here are the ten terms that jwfacts claims the WT uses in reference to the anointed only and therefore (since the great crowd are described with similar terms) must also refer to the great crowd.
1. "great crowd" (already shown to be used in various occassions to many groups of people)
2. "out of all nations and tribes and peoples and tongues" (these terms are also used to describe various peoples and ethnic groups throughout the Christian Greek scriptures)
3. "standing before (enopion) the throne" (terms used ambiguously throughout the scriptures)
4. "before (enopion) the Lamb" (I'll admit this is a unique usage but if there is an earthly class of faithful worshipers such an expression could [though not definitively] be used in reference to those individuals)
5. "dressed in white robes" (Revelation 7:14 says "And he said to me: “These are the ones that come out of the great tribulation, and they have washed their robes and made them white in the blood of the Lamb." As we can see the white robes symbolize the cleansing and repentance of Christ's followers by means of his ransom sacrifice. The term is by no means a 'conclusive description'.)
6. "crying with a loud voice, saying: "Salvation [we owe] to our God, who is seated on the throne, and to the Lamb."" (I don't believe an explanation of this is necessary as it is obvious that all Christians, earthly or heavenly, would owe salvation to Jehovah and Jesus Christ)
7. "come out of the great tribulation" (well since the Great Tribulation occurs on the earth it is by no means conclusive that those who come out of the great tribulation must be in heaven)
8. "washed their robes and made them white in the blood of the Lamb. (this is the same as point 5)
9. "rendering him sacred service day and night in his temple" (in a future post I will show conclusively that this statement does not necessitate the habitation of the great crowd in heaven either)
10. "One seated on the throne will spread his tent over them"(why does God spread his tent over those who are already dwelling among him, before his throne, in his presence in heaven?)
As we can see, the 10 points listed are by no means conclusive and definitive proof. I really do not see what was the point of the author's listing when there are so many uniform nouns and adjectives that describe many different groups of people throughout the Bible (especially the Hebrew Scriptures). Please note I am not asserting that every description or scripture (omitted) was not in reference to the anointed. I am merely asserting that such usage is by no means definitive and determinative.
