Homosexuality refers to attraction between people who are the same sex. It comes from the Greek word homos, meaning “the same.”It is a sexual orientation, as opposed to a gender identity such as male, female, and non-binary. People who are homosexual could refer to themselves as gay, lesbian, LGBTQ, queer, or a number of other terms.

However, this view of homosexuality is a modern concept and it has not always been this way.
The widespread concept of homosexuality as a sexual orientation and sexual identity is a relatively recent development, with the word itself being coined in the 19th century.

There are not even words in the ancient languages which translate to the modern-day “homosexual” and “heterosexual” which were only coined in 1869 CE.

Like the issue with slavery, a major problem with the issue of homosexuality is our modern terms do not correlate with how people in ancient society viewed homosexuality.
The modern conception of sexuality relies on a strict categorisation of sexual appetites and personal desires – heterosexuality, homosexuality, bisexuality, pansexuality, etc. In the ancient world, however, these words did not exist and the concepts they represent were not necessarily analogous to our modern understanding of sexuality.In truth, the projection of utopian ideals of sexual acceptance – particularly in the case of same-sex relationships – onto ancient cultures does not truly capture the complexity and social nuance that surrounded the complex issues of sexuality and desire in the past, and continues to cause controversy in the modern day. The application of modern labels onto sexual attitudes in the past – labels still hotly contested by scholars today – creates the issue of forcing a modern understanding of sexuality onto people who did not necessarily conceptualise sexual identity in the same way we do.

Sexual orientation is a modern idea of which there is no trace either in the New Testament or in any other Jewish or Christian writings in the ancient world. The usual supposition of writers during the Hellenistic period were that homosexual behavior was the result of insatiable lust seeking novel and more challenging forms of self-gratification.
