I don’t know why the Christian churches have such a problem with transgender people. God doesn’t.
According to the Bible, Eve was created using tissue extracted from Adam. Genetically, therefore, she was male.
Also according to the Bible, Jesus was born by parthenogenesis, that is, without any genetic contribution from a male. He had, therefore, a solely uniparental inheritance.
Offspring created in this way do not differ genetically from the mother. Genetically, therefore, he was female.
If God is fine with a trans First Woman and a trans Son, who are Christians to quibble?
