“Approved association with Jehovah’s Witnesses requires accepting the entire range of the true teachings of the Bible, including those Scriptural beliefs that are unique to Jehovah’s Witnesses. What do such beliefs include? …

“That there is a ‘faithful and discreet slave’ upon earth today ‘entrusted with all of Jesus’ earthly interests,’ which slave is associated with the Governing Body of Jehovah’s Witnesses. (Matthew 24:45-47) That 1914 marked the end of the Gentile Times and the establishment of the Kingdom of God in the heavens, as well as the time for Christ’s foretold presence. (Luke 21:7-24; Revelation 11:15–12:10) That only 144,000 Christians will receive the heavenly reward. That Armageddon, referring to the battle of the great day of God the Almighty, is near. (Revelation 16:14, 16; 19:11-21) That it will be followed by Christ’s Millennial Reign, which will restore an earth-wide paradise. That the first to enjoy it will be the present “great crowd” of Jesus’ “other sheep.”—John 10:16; Revelation 7:9-17; 21:3, 4.”
(Quoted from: The Watchtower, 4/1/1986, page 31, Questions From Readers)

The Jehovah’s Witnesses will disfellowship those who don’t believe everything they teach, including their changeable beliefs.

“Of course, Jesus did tell us that his faithful slave would produce perfect spiritual food.” (The Watchtower, 2/1/2017 p.31 par.12)

Now they admit that some of their beliefs may be wrong, but a member will still be disfellowshipped for not believing in them.

 Let’s examine some of the unscriptural beliefs that are unique to the Jehovah’s Witnesses.

1.       Mt 24:45; Lk 12:42-46 – These parables are encouraging faithful Christian activity. They do not identify some special class.

2.       1914 date is unscriptural.

a.       Using Dan 4; Rev 11:2-3; Rev 12:6,14; Lk 21:24; Num 14:34 to arrive at 1914 is arbitrary and presumptuous.

b.      Mt 24:36,44; Mk 13:32,35; Acts 1:8 prove 1914 unscriptural.

c.       Many changes of claims regarding 1914 prove the date was built on sand. (Mt 7:26-27) In fact, every one of their claims about this date made prior to 1914 proved to be false.

3.       1 Tim 2:5 – Jesus mediates the new covenant for all true Christians, not just 144,000. If Jesus died for all, and God wants all to be saved (1 Tim 2:3,6), how is Jesus not the mediator for all?

4.       Heb 10:19-22 – All Christians, not just 144,000 can enter the Holy of Holies into God’s presence through prayer, since the way has been inaugurated by Jesus’ entry into heaven as High Priest. If all Christians are to attend meetings, why can all not go into the Holy of Holies? (Heb 10:24-25)

5.       The Great Crowd – Rev 7:9-17 – Jehovah’s Witnesses claim they are on earth.

a.       The Bible never says they are on earth. ” After this I heard what sounded like the roar of a great multitude in heaven.” (Rev 19:1)

b.      “After this I looked, and there before me was a great multitude that no one could count, from every nation, tribe, people and language, standing before the throne and before the Lamb. They were wearing white robes and were holding palm branches in their hands. ” (Rev 7:9)
This “great multitude” is made up of people from every nation, tribe, people and language, and they are standing before the throne and the Lamb. Where is the throne and the Lamb? In heaven, of course.
“You are worthy to take the scroll and to open its seals, because you were slain, and with your blood you purchased for God persons from every tribe and language and people and nation. You have made them to be a kingdom and priests to serve our God, and they will reign on the earth.” (Rev 5:9-10)
Jehovah’s Witnesses claim these are the 144,000 who will reign in heaven. However, these people from are every nation, tribe, people and language, just like “the great crowd” is, and they will be a kingdom and priests, and they will reign on the earth, according to the Bible.

c.       “All the angels were standing around the throne and around the elders and the four living creatures. They fell down on their faces before the throne and worshiped God.” (Rev 7:11)
Angels were standing around the throne in verse 11 here. If you back up to verse 9, who was also standing before the throne? The great multitude, of course.

d.      “And when he had taken it, the four living creatures and the twenty-four elders fell down before the Lamb. Each one had a harp and they were holding golden bowls full of incense, which are the prayers of God’s people. ” (Rev 5:8)
The four living creatures and the twenty-four elders were before the Lamb here in 5:8. And who was also before the Lamb in Rev 7:9? The great multitude.

e.      “After this I looked, and there before me was a great multitude that no one could count, from every nation, tribe, people and language, standing before the throne and before the Lamb. They were wearing white robes and were holding palm branches in their hands.” (Rev 7:9)
Where did this great multitude get these white robes?
“Then each of them was given a white robe, and they were told to wait a little longer, until the full number of their fellow servants, their brothers and sisters, were killed just as they had been.” (Rev 6:11)

f.        “And they cried out in a loud voice: ‘Salvation belongs to our God, who sits on the throne, and to the Lamb.'” (Rev 7:10)
“After this I heard what sounded like the roar of a great multitude in heaven shouting:

‘Hallelujah! Salvation and glory and power belong to our God.'” (Rev 19:1)

g.       “These are they who have come out of the great tribulation; they have washed their robes and made them white in the blood of the Lamb.” (Rev 7:14)
“For then there will be great distress, unequaled from the beginning of the world until now—and never to be equaled again. If those days had not been cut short, no one would survive, but for the sake of the elect those days will be shortened.” (Mt 24:21-22)
The “elect” are saved  out of the “great distress” or “great tribulation.”

h.      “Blessed are those who wash their robes, that they may have the right to the tree of life and may go through the gates into the city.” (Rev 22:14)
“These are they who have come out of the great tribulation; they have washed their robes and made them white in the blood of the Lamb. (Rev 7:14)
Those who wash their robes are in heaven.

i.         “They are before the throne of God and serve him day and night in his temple; and he who sits on the throne will shelter them with his presence.“ (Rev 7:15)
“What agreement is there between the temple of God and idols? For we are the temple of the living God. As God has said: ‘I will live with them and walk among them, and I will be their God, and they will be my people.'” (2 Cor 6:16)

j.        “They are before the throne of God and serve him day and night in his temple; and he who sits on the throne will shelter them with his presence.“ (Rev 7:15)
“I was given a reed like a measuring rod and was told, ‘Go and measure the temple of God and the altar, with its worshipers. But exclude the outer court; do not measure it, because it has been given to the Gentiles. They will trample on the holy city for 42 months.‘” (Rev 11:1-2)
Not the courtyard, because it has been given to the Gentiles (or nations).

According to the Book of Revelation, the “Great Crowd” is in heaven.
