Tertullian (c. 160 – c. 225), making an exception only for the martyrs, argued that the souls of the dead go down beneath the earth, and will go up to the sky (heaven) only at the end of the world: "You must suppose Hades to be a subterranean region, and keep at arm's length those who are too proud to believe that the souls of the faithful deserve a place in the lower regions … 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, 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, in company with the dead in Christ, who shall be the first to arise? … The sole key to unlock Paradise is your own life's blood.".
