Naturism is the practice of recreational social nudity in a natural environment, such as at a beach, lake, or in a forest or other wilderness area. It is not certain that Christian naturism exists in any formal organisations, however, there are informal (mostly online) networks of Christians who practise naturism.
1 Samuel 19:24 “He (Saul) stripped off his robes and also prophesied in Samuel’s presence. He lay that way all that day and night. This is why people say, ‘Is Saul also among the prophets?'”
Isaiah 20:2–4 The Lord said to Isaiah: “‘Take off the sackcloth from your body and the sandals from your feet.’ And he did so, going around stripped and barefoot. Then the Lord said, ‘Just as my servant Isaiah has gone stripped and barefoot for three years, as a sign and portent against Egypt and Cush, so the king of Assyria will lead away stripped and barefoot the Egyptian captives and Cushite exiles, young and old, with buttocks bared—to Egypt’s shame…'”
Social nudity is the practice of nudity in relatively public settings not restricted by gender. This occurs both in public spaces and on commercial property, such as at a naturist resort.
Some isolated indigenous nudity still exists in the tropics, though this way of life is highly endangered, as is male nude swimming in public, which used to be very commonplace in Western civilization.
Modern European-style naturism began around the turn of the 20th century in British India and Northern Germany, and it was later also adopted in America
Several saints, such as a number of the Desert Fathers as well as Basil Fool for Christ, practiced nudity as a form of ascetic poverty.
In 1981, Pope John Paul II expressed the Catholic Church’s attitude to the exposure of the human body in Love and Responsibility: “The human body can remain nude and uncovered and preserve intact its splendour and its beauty… Nakedness as such is not to be equated with physical shamelessness… Immodesty is present only when nakedness plays a negative role with regard to the value of the person…
The human body is not in itself shameful… Shamelessness (just like shame and modesty) is a function of the interior of a person.
During the 1960s-70s, feminist groups in France and Italy lobbied for and obtained the legalization of topless beaches despite opposition from the Roman Catholic Church.
Spain would eventually permit toplessness on its beaches, but only after the death of ultra-conservative Catholic dictator Francisco Franco in 1975.
Nowadays, most European countries permit toplessless on normal beaches with full nudity allowed only on designated nude beaches.
Despite this, it is quite normal in many parts of Europe to change clothing publicly even if the person becomes fully naked in the process, as this is taken to not count as public nudity.
Around the years 1998-2000 the city of Ottawa grant permission to female volleyball teams to play topless.
Nudity is one of the physiological characteristics of humans, who alone among primates evolved to be effectively hairless. Human sexuality includes the physiological, psychological, and social aspects of sexual feelings and behaviors. In many societies, a strong link between nudity and sexuality is taken for granted. Other societies maintain their traditional practices of being completely or partially naked in social as well as private situations, such as going to a beach or spa. The meaning of nudity and sexuality remains ambivalent, often leading to cultural misunderstandings and psychological problems.
