There will be three Raptures.
Wrong. You made up the barely one and the other two are just one. There is one rapture of the church. It is
the full and complete church leaving no Christian behind. It happens after the GT has ended.
2Th 2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by
our gathering together unto him,
Pre-tribbers usually correctly understand that this gathering of the saints is the rapture.
Mat 24:29 Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
Mat 24:30 And then shall appear the sign of the Son of man in heaven: and then shall all the tribes of the earth mourn, and they shall see the Son of man coming in the clouds of heaven with power and great glory.
Mat 24:31 And he shall send his angels with a great sound of a trumpet, and they shall
gather together his elect from the four winds, from one end of heaven to the other.
Yet, they somehow cannot see that this is same exact gathering/rapture. Both of these are addressing the one and only rapture of the church and it is after the end of tribulation just as Paul said it was:
1Th 4:13 But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope.
1Th 4:14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God
bring with him.
(second coming reference)
1Th 4:15 For this we say unto you by the word of the Lord, that we which are alive and remain unto
the coming of the Lord (second coming reference) shall not prevent them which are asleep.
1Th 4:16 For
the Lord himself shall descend from heaven (second coming reference) with a shout, with the voice of the archangel, and with the trump of God: and
the dead in Christ shall rise first:
(the resurrection of the dead in Christ)
1Th 4:17 Then
we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
(the rapture)
Since Christ brings the dead in Christ with him after the Great Tribulation has ended, we know the above verses are speaking of the 7th trump coming of Christ and the rapture is written by Paul to take place that day.
