History of Christianity and homosexuality

Christian leaders have written about male homosexual activities since the first decades of Christianity; female homosexual behavior was almost entirely ignored. Throughout the majority of Christian history, most Christian theologians and denominations have considered homosexual behavior as immoral or sinful.

However, since the second half of the 20th century some prominent Christian theologians and religious groups have espoused a wide variety of beliefs and practices towards homosexuals, including the establishment of various "open and accepting" Christian churches and denominations that actively support LGBT members.
