This article focuses on the history of homosexuality and Christianity from the beginnings of the Church through the mid 1900s. For current teachings of Christian Churches on homosexuality see Christianity and homosexuality.
Christian leaders have written about homosexual male-male sexual activities since the first decades of Christianity; female-female sexual behaviour was essentially ignored. Throughout the majority of Christian history most theologians and Christian denominations have viewed homosexual behavior as immoral or sinful. However, in the past century some prominent theologians and Christian religious groups have espoused a wide variety of beliefs and practices towards homosexuals, including the establishment of some 'open and accepting' congregations that actively support LGBT members.
Prior to the rise of Christianity, certain sexual practices that people today call "homosexual" had existed among certain groups, with some degree of social acceptance in ancient Rome and ancient Greece (e.g. the pederastic relationship of an adult Greek male with a Greek youth, or of a Roman citizen with a slave). It is believed by some that St. Paul was only addressing such practices in Romans 1: 26–27, while others usually see these verses as condemning all forms of homoeroticism.
Plutarch's Erotikos (Dialogue on Love) argues that, "The noble lover of beauty engages in love wherever he sees excellence and splendid natural endowment without regard for any difference in physiological detail.". He also says, "We regard men who take pleasure in passive submission as practicing the lowest kind of vice.".
The Judaic prohibitions found in Leviticus 18:22 (see also Leviticus 18) and 20:13 address the issue of sex between two men. The latter verse (20:13) says: 'And if a man also lies with mankind, as with womankind, both of them have committed abomination; they shall surely be put to death; their blood shall be upon them."
