This is such a fun conversation. I'm a priest in the Episcopal Church and our denomination has been talking about this for many years now. One of my colleagues made a great counter to the whole "male and female" thing by noting that God also created light and dark and day and night and there's a whole range of things that exist between those two dichotomies.

Also, there's numerous trans readings regarding Jesus within the Bible itself! For instance, Saint Paul notes that Jesus "is the Wisdom of God." Paul is drawing from the wisdom tradition, which depicts God's wisdom as a woman. Further, Saint John's gospel clearly draws from the book known as the Wisdom of Solomon (from the Apocrypha) for his preface, held by many Christians to be the most explicit biblical statement on Jesus' divinity. Later, saints like Julian of Norwich and Anselm of Canterbury would write of Jesus being our Mother. So there's a rich tradition which recognizes Jesus, a He/Him male, embodying long established and celebrated feminine aspects of God (it's for this reason that I don't usually go for swapping the gender of the Father or referring to the Holy Spirit as "She" because I feel like it winds up masking the more clear, and challenging, divine feminine things about Jesus found in the Bible itself). There's definite trans/gender-queer things going on in these texts!

This is one of those "inventing reasons" I'm talking about.
