I've been thinking about transgender issues for a number of years now, but I've been somewhat intimidated at the thought of writing about it. The main reason is that the vocabulary involved is not only endlessly complex, but I've noticed that people who are in-the-know can be very offended when novices like myself come into the discussion and misuse terms. So, in the interest of full-disclosure of my limited knowledge, here's a summary of what I've learned thus far.
I know that you say "transgender" and not "transgendered." I know that there is a difference between "sex" (which has to do with your biological makeup) and "gender" (which has to do with your self-identity). I also know that non-transgender people like myself are called "cisgender." And I've learned that sexual orientation and gender identity issues are separate from each other; that cross-dressing is not necessarily an indication that one is transgender; that the term "transition" means taking steps toward making your outward identity and personal expression match your inner gender identity; and that some people transition "male-to-female" while others transition "female-to-male."
Even though I have found some of the vocabulary terms difficult, the basic human issues are not. For instance, as a straight person writing about gay issues I really had to wrestle with the idea of same-sex sexual orientation, but as someone who is cisgender I relate rather easily to having a strong inner sense of gender identity. I know I'm a woman, not just due to my biology but because I know myself to be female inside. So when I hear that a transgender woman feels the same way I do, except she is in a body that does not properly express her gender identity, the tragedy of that situation hits home.
Few things are more central to our sense of personal identity than gender identity. Through my friendships with gay and lesbian individuals, I've learned just how important sexuality is to us as human beings. When someone says "being gay is who I am" I understand what he or she is trying to express. If sexuality is that important to one's sense of self, gender identity is more so. In the beginning "God created man in his own image . . . male and female he created them" (Genesis 1:27). As creatures of dust, gender is so integral to who we are created to be it is mentioned in the same breath as being made in the image of God.
If you're a Christian, you understand that the world didn't continue on as God originally made it in Genesis 1:27. Because of Adam and Eve's sin we now live in a world that isn't so neat and tidy, which probably has something to do with why some people's gender self-identity doesn't match up with the gender indicated by their biological sex. Perhaps some people are born with a male soul (or male brain) in a female body, or vice versa. Like many fallen conditions this dilemma is nobody's fault, and it is very real and painful to those who are born into it. Unfortunately it cannot be eradicated any more than you can go back in time and eradicate the Fall, so the thing to do is not to quote Bible verses at people as if we are still living in Paradise. Instead we recognize that during this time of Romans 8-style groaning, we need to respond to it as we would to any human pain: with compassion and understanding. I'd suggest, too, that it is wiser not to pass judgment on the decisions people make to alleviate their own pain, especially if you have never walked in their shoes.
Many Christians believe that such talk is dangerous, because it means we won't be taking male and female gender distinctions seriously. I beg to differ. What could be more illustrative of recognizing gender differences than a trans person who feels the need to have his or her outward appearance and presentation match his or her true inner gender? If a trans person is saying that there really is no male and female distinction, then it shouldn't matter to him/her how they present themselves to the outward world. Male . . . female . . . who cares, right? Yet it obviously does matter to them. If you feel you are female inside, you want to look like a female and be accepted as such. The same goes for those who identify as male. The oppressiveness trans people experience when they are treated as if they were one gender when they really identify as the other demonstrates how seriously they take these gender differences.
But here's something else to consider. While God did originally create human beings to be male and female for marriage and procreation in this earthly life, there are also strong hints in the New Testament that in the new heavens and new earth, gender won't be that important. Jesus said that after the resurrection there will be no marrying or giving in marriage because everyone will be like "angels of God in heaven" (Matthew 22:30). Paul said that in Christ "there is neither male nor female" (Galatians 3:28), which is a statement that anticipates the radical equality of men and women existing as co-heirs in heaven. There is no doubt that Paul and Jesus still affirmed and recognized gender distinctions and gender roles in this earthly life. Yet at the same time they were looking beyond to the world to come where we will be so transformed in glory, everything we recognize now as male and female in our earthly bodies will be elevated to such a transcendent existence, we may very well be beyond gender categories. As Jesus said, we will be like the angels.
If a brother or sister in Christ is dealing with being transgender, why not allow them the freedom to seek whatever temporary relief they need to make their earthly journey bearable until all is resolved in glory? Someday the resurrection and glorification of the body will bring permanent peace to the trans individual, but only God can give that gift. In the meantime, the gifts he asks us to give to them as they labor through this earthly pilgrimage are our love, sympathy and understanding.
