Sexual practices between women in the context of "Tribadism"

The blessing or wedding of same-sex marriages and same-sex unions is an issue about which leaders of Christian churches are in ongoing disagreement. Traditionally, Christianity teaches that sexual practices between men and sexual practices between women are sinful and that holy matrimony can only exist between two persons of different sexes. These disagreements are primarily centred on the interpretation of various scripture passages related to homosexuality, sacred tradition, and in some churches on varying understandings of homosexuality in terms of psychology, genetics and other scientific data. While numerous church bodies have widely varying practices and teachings, individual Christians of every major tradition are involved in practical (orthopraxy) discussions about how to respond to the issue.

Some or all sexual acts between men, and less frequently between women, have been classified as a criminal offense in various regions. Most of the time, such laws are unenforced with regard to consensual same-sex conduct, but they nevertheless contribute to police harassment, stigmatization, and violence against homosexual and bisexual people. Other effects include exacerbation of the HIV epidemic due to the criminalization of men who have sex with men, discouraging them from seeking preventative care or treatment for HIV infection.

The criminalization of homosexuality is often justified by the scientifically discredited idea that homosexuality can be acquired or by public revulsion towards homosexuality, in many cases founded on the condemnation of homosexuality by the Abrahamic religions (Judaism, Christianity, and Islam). Arguments against the criminalization of homosexuality began to be expressed during the Enlightenment. Initial objections included the practical difficulty of enforcement, excessive state intrusion into private life, and the belief that criminalization was not an effective way of reducing the incidence of homosexuality. Later objections included the argument that homosexuality should be considered a disease rather than a crime, that criminalization violates the human rights of homosexuals, and that homosexuality is not morally wrong.
