of human sexual activity, including autoeroticism, masturbation, oral sex, non-penetrative and non-heterosexual sexual intercourse (all of which have been labeled as "sodomy" at various times), believing and teaching that such behaviors are forbidden because they're considered sinful, and further compared to or derived from the behavior of the alleged residents of Sodom and Gomorrah. However, the status of LGBT people in early Christianity is debated. Throughout the majority of Christian history, most Christian theologians and denominations have considered homosexual behavior as immoral or sinful. Many commentators have argued that the references to homosexuality in the New Testament, or the Bible in general, have to be understood in their proper historical context. Indeed, most interpreters come to the text with a preconceived notion of what the Bible has to say about normative sexual behaviors, influencing subsequent interpretations. For example, William Walker says that the very notion of "homosexuality" (or even "heterosexuality", "bisexuality" and "sexual orientation") is essentially a modern concept that would simply have been unintelligible to the New Testament writers. The word "homosexuality" and the concept of sexual orientation as being separate from one's perceived masculinity or femininity (i.e. gender identity) did not take shape until the 19th century. Moreover, although some ancient Romans (i.e. doctors, astrologers, etc.) discussed congenital inclinations to unconventional sexual activities such as homosexuality, this classification fails to correspond to a modern psychological, biological and genetic distinction between homosexual, heterosexual and bisexual orientations. However, according to Gagnon, the concept of homosexual orientation was not wholly unknown in the Greco-Roman milieu. Moreover, he asserts that there is absolutely no evidence that modern orientation theory would have had any impact on Paul changing his strong negative valuation of homosexual practice. A statement by the Bishops of the Church of England ("Issues in Human Sexuality") in 1991 illustrates a categorization and understanding of homosexuality, claiming that in ancient times "society recognized the existence of those, predominantly male, who appeared to be attracted entirely to members of their own sex." ("Issues in Human Sexuality" para 2.16, lines 8-9) which almost parallels that of modern ideation. The same study is careful to point out that "the modern concept of orientation has been developed against a background of genetic and psychological theory which was not available to the ancient world." Sarah Ruden, in her Paul Among the People'' (2010) argues that the only form of homosexual sex that was apparent to the
