Irenaeus, on 1Cor 7:31

“And they that use this world, as if they used it not: for the fashion of this world passeth away.”

“For since there are real men, so must there also be a real establishment (plantationem), that they vanish not away among non-existent things, but progress among those which have an actual existence. For neither is the substance nor the essence of the creation annihilated (for faithful and true is He who has established it), but "the fashion of the world passeth away;" that is, those things among which transgression has occurred, since man has grown old in them. And therefore this [present] fashion has been formed temporary, God foreknowing all things; as I have pointed out in the preceding book, and have also shown, as far as was possible, the cause of the creation of this world of temporal things. But when this [present] fashion [of things] passes away, and man has been renewed, and flourishes in an incorruptible state, so as to preclude the possibility of becoming old, [then] there shall be the new heaven and the new earth, in which the new man shall remain [continually], always holding fresh converse with God. And since (or, that) these things shall ever continue without end, Isaiah declares, "For as the new heavens and the new earth which I do make, continue in my sight, saith the Lord, so shall your seed and your name remain."”
