When God talks about nakedness, He says we are to be covered, and that being stripped naked is shameful in His eyes. He applies it both physically and spiritually.
Leviticus 18:6 ‘None of you shall approach anyone who is near of kin to him, to uncover his nakedness: I am the Lord. 7 The nakedness of your father or the nakedness of your mother you shall not uncover. She is your mother; you shall not uncover her nakedness. 8 The nakedness of your father’s wife you shall not uncover; it is your father’s nakedness. 9 The nakedness of your sister, the daughter of your father, or the daughter of your mother, whether born at home or elsewhere, their nakedness you shall not uncover. 10 The nakedness of your son’s daughter or your daughter’s daughter, their nakedness you shall not uncover; for theirs is your own nakedness. 11 The nakedness of your father’s wife’s daughter, begotten by your father—she is your sister—you shall not uncover her nakedness. 12 You shall not uncover the nakedness of your father’s sister; she is near of kin to your father. 13 You shall not uncover the nakedness of your mother’s sister, for she is near of kin to your mother. 14 You shall not uncover the nakedness of your father’s brother. You shall not approach his wife; she is your aunt. 15 You shall not uncover the nakedness of your daughter-in-law—she is your son’s wife—you shall not uncover her nakedness. 16 You shall not uncover the nakedness of your brother’s wife; it is your brother’s nakedness. 17 You shall not uncover the nakedness of a woman and her daughter, nor shall you take her son’s daughter or her daughter’s daughter, to uncover her nakedness. They are near of kin to her. It is wickedness. 18 Nor shall you take a woman as a rival to her sister, to uncover her nakedness while the other is alive.
Leviticus 20:11 The man who lies with his father’s wife has uncovered his father’s nakedness; both of them shall surely be put to death. Their blood shall be upon them. 12 If a man lies with his daughter-in-law, both of them shall surely be put to death. They have committed perversion. Their blood shall be upon them. ... 17 ‘If a man takes his sister, his father’s daughter or his mother’s daughter, and sees her nakedness and she sees his nakedness, it is a wicked thing. And they shall be cut off in the sight of their people. He has uncovered his sister’s nakedness. He shall bear his guilt. ... 19 ‘You shall not uncover the nakedness of your mother’s sister nor of your father’s sister, for that would uncover his near of kin. They shall bear their guilt. 20 If a man lies with his uncle’s wife, he has uncovered his uncle’s nakedness. They shall bear their sin; they shall die childless. 21 If a man takes his brother’s wife, it is an unclean thing. He has uncovered his brother’s nakedness.
Isaiah 3:16 Moreover the Lord says:
“Because the daughters of Zion are haughty,
And walk with outstretched necks
And wanton eyes,
Walking and mincing as they go,
Making a jingling with their feet,
17 Therefore the Lord will strike with a scab
The crown of the head of the daughters of Zion,
And the Lord will uncover their secret parts.”
18 In that day the Lord will take away the finery:
The jingling anklets, the scarves, and the crescents;
19 The pendants, the bracelets, and the veils;
20 The headdresses, the leg ornaments, and the headbands;
The perfume boxes, the charms,
21 and the rings;
The nose jewels,
22 the festal apparel, and the mantles;
The outer garments, the purses,
23 and the mirrors;
The fine linen, the turbans, and the robes.
24 And so it shall be:
Instead of a sweet smell there will be a stench;
Instead of a sash, a rope;
Instead of well-set hair, baldness;
Instead of a rich robe, a girding of sackcloth;
And branding instead of beauty.
25 Your men shall fall by the sword,
And your mighty in the war.
26 Her gates shall lament and mourn,
And she being desolate shall sit on the ground.
Isaiah 47:1 “Come down and sit in the dust,
O virgin daughter of Babylon;
Sit on the ground without a throne,
O daughter of the Chaldeans!
For you shall no more be called
Tender and delicate.
2 Take the millstones and grind meal.
Remove your veil,
Take off the skirt,
Uncover the thigh,
Pass through the rivers.
3 Your nakedness shall be uncovered,
Yes, your shame will be seen;
I will take vengeance,
And I will not arbitrate with a man.” (That's code for: This isn't open for debate.)
(In reference to idols)
Isaiah 57:7 “On a lofty and high mountain
You have set your bed;
Even there you went up
To offer sacrifice.
8 Also behind the doors and their posts
You have set up your remembrance;
For you have uncovered yourself to those other than Me,
And have gone up to them;
You have enlarged your bed
And made a covenant with them;
You have loved their bed,
Where you saw their nudity.
9 You went to the king with ointment,
And increased your perfumes;
You sent your messengers far off,
And even descended to Sheol.
10 You are wearied in the length of your way;
Yet you did not say, ‘There is no hope.’
You have found the life of your hand;
Therefore you were not grieved.
11 “And of whom have you been afraid, or feared,
That you have lied
And not remembered Me,
Nor taken it to your heart?
Is it not because I have held My peace from of old
That you do not fear Me?
And are you unfamiliar with Ezekiel 16 and 23? God clothed naked Israel and Judah, but they went and played the harlot, forgetting their former shame which was manifest by there nakedness?
Revelation 3:14 “And to the angel of the church of the Laodiceans write,
‘These things says the Amen, the Faithful and True Witness, the Beginning of the creation of God: 15 “I know your works, that you are neither cold nor hot. I could wish you were cold or hot. 16 So then, because you are lukewarm, and neither cold nor hot, I will vomit you out of My mouth. 17 Because you say, ‘I am rich, have become wealthy, and have need of nothing’—and do not know that you are wretched, miserable, poor, blind, and naked— 18 I counsel you to buy from Me gold refined in the fire, that you may be rich; and white garments, that you may be clothed, that the shame of your nakedness may not be revealed; and anoint your eyes with eye salve, that you may see. 19 As many as I love, I rebuke and chasten.
Revelation 16:15 “Behold, I am coming as a thief. Blessed is he who watches, and keeps his garments, lest he walk naked and they see his shame.”
So, at a minimum, you must agree that if a son or daughter is there, it is not proper, as the Lord says they should not look on the nakedness of their relations (see Noah when he got drunk). So, were people there with more than one generation in any family? If so, that is clearly condemned by God.
And still, nobody has said word one about their primary mission in attending such places being to glorify God. Why?
You can play word games all day long, but the fact of the matter is that it is sin. No honest reading of the whole scripture provides any other conclusion. God uses physical nakedness as a picture, as a type, of spiritual nakedness. He says it is shameful. Compounding your actions to be involved with such activities, you disregard the offense you cause other believers here who obviously have a problem with it. Yet, you express no concern about your responsibility to others, when they are tempted to sin, when you take your "liberty". If you want to put a bullseye on someone, I have a problem with it. The same problem Peter had with it after Jesus rose from the dead. He was embarrassed by his nakedness before the Lord, and think you that you are any less naked before Almighty God when you are naked in public, in a presumably less acceptable way than Peter was? So far as we can tell in scripture, Peter wasn't in mixed company. Yet, he had the good sense to be ashamed. No, no amount of words will justify your claims that it is okay. You may convince some that it is okay, but that isn't how you judge truth. And you will bear the punishment for causing brothers and sisters to stumble, which make no mistake, you are causing people to stumble, even though you seem unwilling to ackknowlege that fact. And you will have no answer when God finally calls you to account causing people to stumble. Have you the Spirit of God? Then be discerning, and do not pursue those sensual things which are spoken of in Jude. And keep in mind the warning of Paul in Romans 1, where God gave people over to a reprobate heart because they worshipped that which was created, which in this case is the naked body, instead of worshipping God.
