Is Sexual Intercourse Between Siblings Morally Permissible?

[linwood]

Jeez, don't get all snippety.

I think there's more to definitions of morality than what does and does not hurt anybody, or what is or isn't "icky".

Do you mind saying what those definitions of morality are?

 

[St Giordano Bruno]

There may be issues with epidemiology such as issues with genetic disorders, especially if the siblings a carrying a recessive genetic disorder such as cystic fibrosis which could be brought to the fore. But I do not see any such problems if they use protection with a condom.

Is Sexual Intercourse Between Siblings Morally Permissable?

Here's what the Bible says:

Leviticus 18:6-18





6 “You must never have sexual relations with a close relative, for I am the Lord.
7 “Do not violate your father by having sexual relations with your mother. She is your mother; you must not have sexual relations with her.
8 “Do not have sexual relations with any of your father’s wives, for this would violate your father.
9 “Do not have sexual relations with your sister or half sister, whether she is your father’s daughter or your mother’s daughter, whether she was born into your household or someone else’s.
10 “Do not have sexual relations with your granddaughter, whether she is your son’s daughter or your daughter’s daughter, for this would violate yourself.
11 “Do not have sexual relations with your stepsister, the daughter of any of your father’s wives, for she is your sister.
12 “Do not have sexual relations with your father’s sister, for she is your father’s close relative.
13 “Do not have sexual relations with your mother’s sister, for she is your mother’s close relative.
14 “Do not violate your uncle, your father’s brother, by having sexual relations with his wife, for she is your aunt.
15 “Do not have sexual relations with your daughter-in-law; she is your son’s wife, so you must not have sexual relations with her.
16 “Do not have sexual relations with your brother’s wife, for this would violate your brother.
17 “Do not have sexual relations with both a woman and her daughter. And do not take her granddaughter, whether her son’s daughter or her daughter’s daughter, and have sexual relations with her. They are close relatives, and this would be a wicked act. 18 “While your wife is living, do not marry her sister and have sexual relations with her, for they would be rivals.
