You may not agree that it is unnatural, and that is certainly your prerogative, but the Bible certainly doesn't agree with you on that point.From the link: People have a basic, ethical intuition that certain behaviors are wrong because they are unnatural. We perceive intuitively that the natural sex partner of a human is another human, not an animal.
The same reasoning applies to the case of homosexual behavior. The natural sex partner for a man is a woman, and the natural sex partner for a woman is a man. Thus, people have the corresponding intuition concerning homosexuality that they do about bestiality—that it is wrong because it is unnatural.
Sorry, that doesn’t fly at all.
You make some good points as to inconsistencies in the attitude of churches towards different categories of (habitual) sin. However, a couple of counterpoints on that subject:
- A lot of church's certainly did, in the past, ex-communicate or refuse fellowship for parishioners for a wide range of sins. Modernity and changing attitudes gradually and then more forcibly led church after church to change their practices and views, for better or worse. This is just another example. One that many find harder to accept, and some of the reasons cited undoubtably play a role.
- You ask how one is to determine whether someone is an habitual sinner vs someone who is just struggling with a weakness and "back-sliding". It's a valid question, no doubt. However, in the case of an openly gay person or a church that states they are accepting openly gay people as Christian members of their church, and certainly in the case of married gay couples --- there is NO attempt to repent from the sin. The view is that it is OK, so the question you asked is moot in that situation.
