First dealing with the error in the first answer. It the 3rd paragraph the author specifically calls naturism sin when he/she writes "... it attempts to deal with the "sin" by stating that it is simply man's invention ... "
nakedness cannot be sin because last verse of Genesis 1 and Genesis 2 tell us that the man and woman were naked and that God saw that "... it was very good."
Also in Isa 20:2 God commanded his prophet Isa to go naked for 3 years, and yes that really was NAKED! as it symbolized the naked/barefoot/"buttocks uncovered" condition the Egyptians and Ethiopians would experience when they were taken away as prisoners of war and slaves.
Likewise contending that the "concept of naked" is some invention of mankind appears to miss the mark. as is reveled by God's question in Genesis 3:11 when God asks "Who told thee that thous wast naked". It hardly makes sense that God would have asked that if the idea had not come from the serpent. As for God clothing Adam and Eve in Genesis 3:21, one should apply the principle of examining the context and one will see that 3 verses previous in Genesis 3:18 God had just said he was sending them into a world with thorns and thistles, and then note that in verse 21, those clothes were made of LEATHER! a material appropriate for repelling thorns. The context suggests that the clothing was needed for protection and not covering up God's "capstone of earthly creation". Clothing is protection when needed, which is why it is a shame when people do not have it because of poverty or being denied it because of their state of captivity.
Now to answer the original question:
The question is stated in the negative asking in which denominations is it unacceptable. The societal aversion to nudity is so broadly spread that to avoid condemnation from lay members, or disrupting congregations, or sowing discord among the brethern; it is perhaps better to seek an answer to the converse, "In which denominations is naturism well tolerated?" Quakers have a great tolerance for nudity, having practiced it as a religious statement in times past. Lutherans are said to have tolerance for it (may vary by synod). and the previous pope has said that the naked body is not sinful. However the problem is that what is the viewpoint of the denomination may not be reflected in the practice of the local congregations. So it is best to check it out with the pastor and/or deacons or others in the local hierarchy. An accurate picture of the official position of the denomination might be more likely obtained by searching for the denomination's web site and asking the question there.
