We don't need to think abstractly about this. The NKJV commentary on 2 Corinthians 5 (thus not Mark per se but the letters of Paul which in turn speaks to a wider Christian understanding):
Ancient writers sometimes portrayed the present or resurrected body as clothing and death as disrobing. Judeans and other eastern peoples loathed nudity; while Greeks and Romans disliked it in particular situations, both bathed naked in the baths and Greeks exercised naked. For Paul, the image is undesirable—the body's death is not in itself desirable, in contrast to the view of some philosophers (especially Platonists) who viewed positively the soul's release from the body. For the body as clothing, see 1 Cor. 15.53- 55
The material as Clement had it (which is slightly different than our own received text) again:
For we know, that, if the earthly house of our tabernacle be dissolved, we have a building of God, an house not made with hands, eternal in the heavens. For we that are in this tabernacle do groan, desiring to be clothed upon with our house which is from heaven: if so be that being clothed we shall not be found naked. For we walk by faith not by sight and we are willing rather to be absent from the body and present with God. Wherefore we strive whether present or absent to be accepted with Him.
Clement Stromata 4.26
Now the soul of the wise man and Gnostic, as sojourning in the body, conducts itself towards it gravely and respectfully, not with inordinate affections, as about to leave the tabernacle if the time of departure summon. "I am a stranger in the earth, and a sojourner with you," it is said. And hence Basilides says, that he apprehends that the election are strangers to the world, being supramundane by nature. But this is not the case. For all things are of one God. And no one is a stranger to the world by nature, their essence being one, and God one. But the elect man dwells as a sojourner, knowing all things to be possessed and disposed of; and he makes use of the things which the Pythagoreans (Περιπατητικοὶ) make out to be the threefold good things. The body, too, as one sent on a distant pilgrimage, uses inns and dwellings by the way, having care of the things of the world, of the places where he halts; but leaving his dwelling-place and property without excessive emotion; readily following him that leads him away from life; by no means and on no occasion turning back; giving thanks for his sojourn, and blessing [God] for his departure, embracing the mansion that is in heaven "For we know, that, if the earthly house of our tabernacle be dissolved, we have a building of God, an house not made with hands, eternal in the heavens. For we that are in this tabernacle do groan, desiring to be clothed upon with our house which is from heaven: if so be that being clothed we shall not be found naked. For we walk by faith, notby sight," as the apostle says; "and we are willing rather to be absent from the body, and present with God." The rather is in comparison. And comparison obtains in the case of things that fall under resemblance; as the more valiant man is more valiant among the valiant, and most valiant among cowards. Whence he adds, "Wherefore we strive, whether present or absent, to be accepted with Him," that is, God, whose work and creation are all things, both the world and things supramundane. I admire Epicharmus, who clearly says: "Endowed with pious mind, you will not, in dying, Suffer aught evil. The spirit will dwell in heaven above;" and the minstrel who sings: "The souls of the wicked flit about below the skies on earth, In murderous pains beneath inevitable yokes of evils; But those of the pious dwell in the heavens, Hymning in songs the Great, the Blessed One."
And they say that the robe prophesied the ministry in the flesh, by which He was seen in closer relation to the world. So the high priest, putting off his consecrated robe (the universe, and the creation in the universe, were consecrated by Him assenting that, what was made, was good), washes himself, and puts on the other tunic -- a holy-of holies one, so to speak -- which is to accompany him into the adytum; exhibiting, as seems to me, the Levite and Gnostic, as the chief of other priests (those bathed in water, and clothed in faith alone, and expecting their own individual abode), himself distinguishing the objects of the intellect from the things of sense, rising above other priests, hasting to the entrance to the world of ideas, to wash himself from the things here below, not in water, as formerly one was cleansed on being enrolled in the tribe of Levi. But purified already by the gnostic Word in his whole heart, and thoroughly regulated, and having improved that mode of life received from the priest to the highest pitch, being quite sanctified both in word and life, and having put on the bright array of glory, and received the ineffable inheritance of that spiritual and perfect man, "which eye hath not seen and ear hath not heard, and it hath not entered into the heart of man;" and having become son and friend, he is now replenished with insatiable contemplation face to face. For there is nothing like hearing the Word Himself, who by means of the Scripture inspires fuller intelligence. For so it is said, "And he shall put off the linen robe, which he had put on when he entered into the holy place; and shall lay it aside there, and wash his body in water in the holy place, and put on his robe." But in one way, as I think, the Lord puts off and puts on by descending into the region of sense; and in another, he who through Him has believed puts off and puts on, as the apostle intimated, the consecrated stole. Thence, after the image of the Lord. the worthiest were chosen from the sacred tribes to be high priests, and those elected to the kingly office and to prophecy were anointed
For it is impossible that he who has been once made perfect by love, and feasts eternally and insatiably on the boundless joy of contemplation, should delight in small and grovelling things. For what rational cause remains any more to the man who has gained "the light inaccessible," for revering to the good things of the world? Although not yet true as to time and place, yet by that gnostic love through which the inheritance and perfect restitution follow, the giver of the reward makes good by deeds what the Gnostic, by gnostic choice, had grasped by anticipation through love. For by going away to the Lord, for the love he bears Him, though his tabernacle be visible on earth, he does not withdraw himself from life. For that is not permitted to him. But he has withdrawn his soul from the passions. For that is granted to him. And on the other hand he lives, having put to death his lusts, and no longer makes use of the body, but allows it the use of necessaries, that he may not give cause for dissolution.
“Finally, from so little sleeping and so much reading, his brain dried up and he went completely out of his mind.”
