Gentile church rapture is in Paul's writings. Matthew is Jewish in nature and does not contain the Gentile body of Christ.
Paul says "At the last trumpet"
1 Corinthians 15:51-55, “See, I speak a secret to you: We shall not all sleep, but we shall all be changed, in a moment, in the twinkling of an eye,
at the last trumpet. For the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed. For this corruptible has to put on incorruption, and this mortal to put on immortality. And when this corruptible has put on incorruption, and this mortal has put on immortality, then shall come to be the word that has been written, “Death is swallowed up in overcoming. O Death, where is your sting? O grave, where is your overcoming?”
That is the 7th trumpet, it ends the tribulation and starts the wrath...
Revelation 11:15-18, 15 And
the seventh messenger sounded, and there came to be loud voices in the heaven, saying, “The reign of this world has become the reign of our Master, and of His Messiah, and He shall reign forever and ever!”16 And the twenty-four elders sitting before Elohim on their thrones fell on their faces and worshipped Elohim, 17 saying, “We give You thanks, O יהוה Ěl Shaddai, the One who is and who was and who is coming, because You have taken Your great power and reigned. 18 “And the nations were enraged, Psa 2:1 and
Your wrath has come, and the time of the dead to be judged, and to give the reward to Your servants the prophets and to the set-apart ones, and to those who fear Your Name, small and great, and to destroy those who destroy the earth.”
Also Yahshua does not say a certian people He says HIS CHOSEN
Mat 24:29-31, “And immediately
after the tribulation of those days the sun shall be darkened, and the moon shall not give its light, and the stars shall fall from the heaven, and the powers of the heavens shall be shaken. And then the sign of the Son of Aḏam shall appear in the heaven, and then all the tribes of the earth shall mourn, and they shall see the Son of Aḏam coming on the clouds of the heaven with power and much esteem. And He shall send
His messengers with a great sound of a trumpet, and they shall gather together His chosen ones from the four winds, from one end of the heavens to the other.”
sounds like all of them from the WHOLE earth to me...
