B T G will be completely burned with fire (Rev 17:18) - completely destroyed. WT 7/15 2013: 7 Jesus also foretold: “Those days will be cut short.” In the initial fulfillment, this happened in 66 C.E. when the Roman army “cut short” its attack. Then, anointed Christians in Jerusalem and Judea fled, allowing for their ‘flesh, or life, to be saved.’ (Read Matthew 24:22; Mal. 3:17) So, what can we expect will happen during the coming great tribulation? Jehovah will “cut short” the attack of the United Nations on false religion, not allowing true religion to be destroyed with the false. This will ensure that God’s people will be saved. 8 What happens after the initial part of the great tribulation has passed? Jesus’ words indicate that there will be a period of time that will last until the start of Armageddon. What events will occur during that interval? The answer is recorded at Ezekiel 38:14-16 and Matthew 24:29-31. (Read.) After that, we will witness Armageddon, the climax of the great tribulation, which parallels Jerusalem’s destruction in 70 C.E. (Mal. 4:1) With the battle of Armageddon as its climax, that coming great tribulation will be unique—an event “such as has not occurred since the world’s beginning.” (Matt. 24:21) When it has passed, Christ’s Millennial Rule will begin." So false religion will be completely gone - however God's people don't need a building or a priest or "pope" to still be functioning.
