On my naturist camping webiste I go into depth on this topic, but in a nutshell, if you get an electronic version of the Bible an do a word search on naked, nakedness, nude, bare, stripped, etc., AND read each reference IN CONTEXT (in other words, read what comes before and after), and if you do this with no pre-conceived ideas on the subject, you will see that the Bible in no way condemns nakedness. It does recognize that many people find nakedness shameful, but it does not say we should find it shameful.
Read in context, the one verse normally used to teach anti-nakedness is actually telling us not to OVERDRESS in church, but to clothe ourselves in good works!
