Tertullian

“ When the world, indeed, shall pass away, then the kingdom of heaven shall be opened. Shall we then have to sleep high up in ether, with the boy-loving worthies of Plato; or in the air with Arius; or around the moon with the Endymions of the Stoics? No, but in Paradise, you tell me, whither already the patriarchs and prophets have removed from Hades in the retinue of the Lord’s resurrection. How is it, then, that the region of Paradise, which as revealed to John in the Spirit lay under the altar, [10] displays no other souls as in it besides the souls of the martyrs? ”

“ How, indeed, shall the soul mount up to heaven, where Christ is already sitting at the Father’s right hand, when as yet the archangel’s trumpet has not been heard by the command of God, [7] —when as yet those whom the coming of the Lord is to find on the earth, have not been caught up into the air to meet Him at His coming, [8] in company with the dead in Christ, who shall be the first to arise? [9] To no one is heaven opened; the earth is still safe for him, I would not say it is shut against him. ”
