1 Corinthians 15:35,40-42 How Celestial angels can appear

³⁵ But some man will say, How are the dead raised up? and with what body do they come?... ⁴⁰ There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another. ⁴¹ There is one glory of the sun, and another glory of the moon, and another  glory of the stars: for one star differeth from another star in glory. ⁴² So also is the resurrection of the dead... -1 Corinthians 15:35-42 Bible, King James Version 

Conjugial Love, by Emanuel Swedenborg, [1768] at sacred-texts.com

137.

...On a time when I was meditating on conjugial love [love in a marriage relationship,] lo! there appeared at a distance two naked infants with baskets in their hands, and turtledoves flying around them; and on a nearer view, they seemed as if they were naked, handsomely ornamented with garlands; chaplets of flowers decorated their heads, and wreaths of lilies and roses of a hyacinthine blue, hanging obliquely from the shoulders to the loins, adorned their bosoms; and round about both of them there was as it were a common band woven of small leaves interspersed with olives. But when they came nearer, they did not appear as infants, or naked, but as two persons in the prime of their age, wearing cloaks and tunics of shining silk, embroidered with the most beautiful flowers: and when they were near me, there breathed forth from heaven through them a vernal warmth, attended with an odoriferous fragrance, like what arises from gardens and fields in the time of spring. They were two married partners from heaven, and they accosted me; and because I was musing on what I had just seen, they inquired, "What did you see?" And when I told them that at first they appeared to me as naked infants, afterwards as infants decorated with garlands, and lastly as grown up persons in embroidered garments, and that instantly I experienced a vernal warmth with its delights, they smiled pleasantly, and said, "In the way we did not seem to ourselves as infants, or naked, or adorned with garlands, but constantly in the same appearance which we now have: thus at a distance was represented our conjugial love; its state of innocence by our seeming like naked infants, its delights by garlands, and the same delights now by our cloaks and tunics being embroidered with flowers; and as you said that, as we approached, a vernal warmth breathed on you, attended with its pleasant fragrance as from a garden, we will explain to you the reason of all this." They said, "We have now been married partners for ages, and constantly in the prime of our age in which you now see us..." "He further added, "With us in heaven there is perpetual light, and on no occasion do the shades of evening prevail, still less is there darkness; because our sun does not set and rise like yours, but remains constantly in a middle altitude between the zenith and the horizon, which, as you express it, is at an elevation of 45 degrees. Hence, the heat and light proceeding from our sun cause perpetual spring, and a perpetual vernal warmth inspires those with whom love is united with wisdom in just proportion... [The] males of the human race were created to be recipients of light, that is, of wisdom from the Lord, and the females to be recipients of heat, that is, of the love of the wisdom of the male from the Lord. Hence then it is, that, as we approached, there breathed on you a vernal warmth attended with an odoriferous fragrance, like what arises from gardens and fields in the spring." As he said this, he gave me his right hand, and conducted me to houses inhabited by married partners in a like prime of their age with himself and his partner; and said, "These wives, who now seem like young virgins, were in the world infirm old women; and their husbands, who now seem in the spring of youth, were in the world decrepit old men; and all of them were restored by the Lord to this prime of their age, because they mutually loved each other, and from religious motives shunned adulteries as enormous sins:" and he added, "No one knows the blessed delights of conjugial love, unless he rejects the horrid delights of adultery; and no one can reject these delights, unless he is under the influence of wisdom from the Lord; and no one is under the influence of wisdom from the Lord, unless he performs uses [the action of using something or the state of being used for a purpose] from the love of uses." I also saw on this occasion their house utensils, which were all in celestial forms, and glittered with gold, which had a flaming appearance from the rubies with which it was studded.
