I am not at all surprised.
In discussions with my priest, I was told that there is really not any church doctrine on transgender.
I have also noticed how Pope Francis wants to welcome people into the church, not condemn them. That is a good thing. We have support ministries for divorcees and women who have had abortions, for example.
However, I don't know if there will be openly gay vatican sanctioned priests or same sex weddings in church anytime soon. I was also warned that as soon as I change my gender, our marriage will be invalid in the eyes of the church. I'm not sure exactly what "change my gender" means, I mean I am already female, and I can get the official designation changed legally without surgery. Does he mean change the marriage record?
