It’s a double edged sword in that it can go wither way and there could be many reactions as it is a christian community. If you go you may find acceptance with some, an okay, but I am not sure and outright rejection from others. The key is that you are part of this group and, no matter how you dress, this is you who wishes to be part of that. I would say go and be of an open mind as to the reactions and see where it goes.
It has to be said this is an issue for trans in whatever setting. I wish you well.
