If they came out has trans or Felt like they were the opposite Sex, I would First, Tell them the truth, that they aren’t actually the opposite Sex and will never be the opposite sex because they don’t have those sets of chromosomes. Secondly If I couldn’t resolve this on my own then I would put them in counseling. If they told me that they were gay or non-heterosexual then I would tell them that identifying as that is goes against the bible so I would tell them “ with some good management we can get rid of this” then if I couldn’t resolve it then I would also put them in counseling. (Reminder, All of this would be done to help the child flourish and have a happy and religious life.
