Yesterday's post on unnatural things not necessarily being sinful could obviously apply to homosexuality. Plenty of Christians state homosexuality is both unnatural and sinful. There are many statements of faith and behavioral contracts that state all sexual activity must exist only within the confines of a heterosexual marriage.
From this perspective, would it be acceptable for two men or two women who are in love to be in a celibate relationship?
Could a man and a woman live together out of wedlock while not engaging in any sexual activity?
If the sin is sex and we remove the sex, is the problem solved?
