Adultery is a heterosexual act. By condemning adultery, does the Bible condemn heterosexuality? No. It only condemns a particular action. An action which happens to be heterosexual by nature, but still just an action nonetheless. And so it is with homosexuality. The actions are condemned, but the state of being homosexual--having that orientation--is not condemned anymore than heterosexuality is condemned because of the prohibition on adultery. Now if heterosexuals engage in adultery or homosexuals engage in sodomy, then yes, they become guilty. But prior to committing the act, they possess no guilt. Your problem is that you cannot break out of your Enlightenment concept of sexuality and are thus reading it into a religious text that was composed at a time when such a concept never existed. What I am trying to tell you is that within the biblical framework, sexuality is not defined by orientation but by action, nor does having a particular orientation mean that you are destined to engage in that particular action. Just as heterosexual monastics refrain from all sex via celibacy, and even all married heterosexual religious people refrain from certain heterosexual abominations like adultery (or are at least expected to), so it is with homosexuals. In other words, being homosexual does not always entail that you will engage in homosexual actions--again, Blessed Seraphim Rose, a homosexual who lived a life of celibacy following his religious conversion. Nor does it mean that homosexuals are somehow excused from their actions because their orientation "made" them do it, anymore than testosterone vindicates a r@pist.
