From the Salvation Army's website:
Sexual attraction to the same sex is a matter of profound complexity. Whatever the causes may be, attempts to deny its reality or to marginalize those of a same-sex orientation have not been helpful. The Salvation Army does not consider same-sex orientation blameworthy in itself. Homosexual conduct, like heterosexual conduct, requires individual responsibility and must be guided by the light of scriptural teaching.Scripture forbids sexual intimacy between members of the same sex. The Salvation Army believes, therefore, that Christians whose sexual orientation is primarily or exclusively same-sex are called upon to embrace celibacy as a way of life. There is no scriptural support for same-sex unions as equal to, or as an alternative to, heterosexual marriage.
