Is there any proof or evidence that homosexuality is morally wrong?

[John S]

As is often the case, I think to truly answer this question, one must take a step back and FIRST discuss the concept of Absolute Morality vs. Subjective Morality.

Because IF one side of the discussion believes in subjective morality, then it will be nearly impossible for the other side of the argument (who we presume believes in absolute morality) to show anything that is convincing, because in the end, ANY evidence that homosexuality is illmoral would undoubtedly rest on the idea that there is such a thing as an absolute morality.

But then the issue of absolute morality raises the issue of WHO sets the rules? Absolute morality doesn't work unless you have some higher power to set the rules.

Secondly.. you then need to have a serious discussion about the purpose and design of human sexuality and the reason that sex exists. -- This issue will again, most likely start to delve into this idea of absolute morality and a higher power.
IS sex merely a pleasurable activity that humans are free to engage in with whomever and however they want? OR, is human sexuality ordered towards some ultimate and higher purpose?
This is typically where people invoke 'natural law' -- which often times gets confused with "laws of nature" -- 2 totally different things.

So the issue gets complicated and to be discussed in depth, one needs to step back and define a few other terms ahead of time.

As a Catholic.. I don't have 'proof positive' of very many things in life. But because Catholicism believes in absolute morality set by God and a philosophical concept called "natural law" - both of which put limits on what man 'ought to do' - I would say that I believe that homosexual sex acts are contrary to the intrinsic design of sex and God's intention for how we are to express our sexuality.

But to explain all that indepth, would take a long time.
