I am a Christian and had been a member of my church for 5 years when I finally made the decision to transition. I had had numerous discussions with my minister (I'd actually talked with 3-4 ministers over the course of my life) about my situation. He had always been supportive of my desire to be whole. Actually all the ministers I'd talked with had.
I'd come to a point where I'd decided I was either going to do it or never think about it again. So I prayed a lot about it and decided to open up to some members of my church that I trusted and respected and asked what they thought. They were very supportive. So they whatched as my changes happened, called me by my new name (the pronoun change took a little longer, but they got it!) and now everything is back to normal, with one member a whole lot happier. I was surprised at how well the children did. They were much quicker with the pronouns. Parent would tell me the questions their kids asked and it was so cute and innocent. Except for several members that left the church because of this, I think everyone did exceptionally well. They stood behind me and I will always be grateful for that.
I believe God has been with my through every step of my life (read Psalm 139) and I praise Him for helping me through this journey. He gave me angels to help make my load lighter and my path easier.
