There are several passages in the bible
that are said to refer to homosexuality
. And these passages are also said to state how homosexuality is a sin
, or is wrong or is an abomination or is unnatural etc.
Such passages include Leviticus 18:22, this particular reference is undisputable. However, also under the sins listed in Leviticus are shaving (Leviticus 19:27 and Leviticus 21:5) and many other such things. Clearly Christians do not follow Levitical law, so this reference, when dealing with Christianity, is useless.
Other passages include 1 Corinthians 6:9-10. The problem here is that the King James Version as well as others has a rather blinding set of mistranslations.
6:9 Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
Both the terms "effiminate" and "abusers of themselves with mankind" are not mentioned at all in the original Greek manuscript. The words that should be here are malekoi (meaning soft, possibly referring to soft morals, or no moral conviction) and arsenkoitai.
Arsenkoitai is a word that Paul made up. There is no definition of what it means, and to break it down into its components (arsen=male koitai=bed) give a result like "Male active bed" or other such nonsense terms like "Man in a bed". This has mostly been translated into homosexual references. It could refer to multiple marriages, promiscuousness or even laziness.
Most of the New Testament references to homosexuality are written by Paul and were mistranslated by power hungry priests who would have another set of witches to burn.
The only other reference that cannot be easily dismissed as a translation error is in Romans 1:27
"And likewise also the men, leaving the natural use of the woman, burned in their lust one toward another; men with men working that which is unseemly, and receiving in themselves that recompence of their error which was meet. "
This however does not mention that homosexuality is a sin, or is wrong. In fact Romans 1 is a big list of things which people would find terrible and "sinful" or rather "unseemly". Then Paul catches everybody in their judgementalism in Romans 2:1
"Therefore thou art inexcusable, O man, whosoever thou art that judgest: for wherein thou judgest another, thou condemnest thyself; for thou that judgest doest the same things. "
