Hopefully, one day we will not need such a term as transgender because we will all be able to express our identities freely. On the one hand, these sources of authority say absolutely nothing about transgender. Some biblical passages that may seem appropriate are, in fact, irrelevant when studied carefully relative to contemporary understandings of gender and human sexuality. Each member must seek the grace of openness in extending the fellowship of Christ to all persons. On the one hand this is a complex question because transgendered people can, like anyone else, experience their sexual orientation in any direction.
Gender identity is distinct from and more basic than sexual orientation.
One's sense of being male or female necessarily precedes one's affectional attractions. Moreover, as it concerns all humankind, there is absolutely nothing simple about being sexual. There are, indeed, some transgendered people who are homosexual. Some transgendered people are even attracted to other transgendered people, and that classification hasn't even been named. On the other hand, the transgender phenomenon renders these categories moot.
