Surely no one would tell a woman that she can't attend church if her attire is modest, proper, and decent (Lewis' words) according to the standard of the society where that church is.
CS Lewis would say that in that context, YES, a woman could attend church topless.
Do you disagree with CS Lewis?
If so, how is his logic flawed?
What did Adam and Eve realize immediately after they ate from the tree of the knowledge of good and evil? What did God do for them afterwards? In short, no, I do not agree with C.S. Lewis, at least on this topic. Christian culture and secular culture have very little overlap, however, of that little overlap, western secular and Christian culture tend to agree that modest clothing for women would be covered shoulders, breasts, mid-rift, and genitalia, with shorts coming to the knees or slightly above. Also, clothing that's not so tight it's essentially a second layer of skin. Some are a little more liberal, and some are a little more conservative, but I think that's a safe middle-ground definition of what western culture deems as modest.
So the question you asked can be restated as "Why does God hate sexual impurity?" Fair enough?
No... The Koine Greek was translated to "sensuality". Sensuality may encompass sexual impurity, but there's more to the word than this one concept. Otherwise the translation would have been to "sexual impurity".
As defined, God does NOT hate "sensuality"
Well, it's listed right there in things that will keep you OUT of his kingdom... I'll agree with you that God want's us to enjoy creation within the bounds of his commands, however, it is obvious that sensuality, in a biblical context, is referring to the overindulgence of said enjoyment.
Galatians 5:19-21: "Now the works of the flesh are evident: sexual immorality, impurity,
sensuality, idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions, envy, drunkenness, orgies, and things like these. I warn you, as I warned you before, that those who do such things will not inherit the kingdom of God."
Your claim was that these passages linked clothing to sensuality. Your claim here that clothing CAN be a sexual/sensual expression... that's true enough...
You've agreed that it is possible to express sexuality, and even sensuality, by the clothing you choose to wear.
Now that I've answered your question about why "God hates sensuality," you need to answer my question about which female body parts are offensive to God and therefore sinful to leave uncovered.
Lol. Talk about straw men. You know I'm going to say God is not offended by the body he created, and I know you are going to use that to claim that no one else should be offended by it either. I never asked what God thought of our naked bodies though, so...yeah. I'm glad you brought this up though, because it plays into the next question I have for you.
Let's pull all this information together.
a. Sensuality is a sin in the biblical sense of the word.
b. The clothes you wear can express sensuality/be sensual.
c. God is not offended by the human body.
d. God is not tempted by evil, nor does he tempt anyone "James 1:13".
Put into one logical statement:
While sensuality, as expressed through clothing or other means, is considered sinful in a biblical context, this does not imply that God is offended by the human body itself.
Now for my next question to you. If God is not offended by the human body itself, why would sensuality, which can include our manner of dress, be included in a list of things that will keep you from entering God's kingdom, as well as be spoken against in several other verses?
