Well, since you ask.

I am Unitarian-Universalist, so I didn't have quite as high a step to make as some do. I was very methodical about coming out to my church.
First, I talked to my minister. She was very supportive. Then I came out to a number of friends in the church, one at a time. They were all accepting; some were very supportive.
Next, I wrote a little speech and practiced it a gazillion times so that I could just do it on automatic, because I knew I would be nervous.
There is a place in the service when we can go up and light a candle of joy or concern – our son got admitted to grad school or our father is in the hospital, that sort of thing.
I told the minister that I was going to do it the next Sunday if I didn't lose my nerve. She asked if I wanted her to light the candle for me, since I'd be nervous. I told her I'd signal her if I needed help.
I also told my friends, so they would be there to support me. I asked a couple of them to sit in the back and signal me if I wasn't speaking loud enough, because I wanted everyone to hear the first time. Several friends asked if I wanted them to go up to stand with me. I considered it but thought it was something I needed to do on my own.
I came out on Easter Sunday. I liked the symbolism. I went up, lit a candle, faced the congregation, and spoke:
"I wanted to light a candle today
In joy for this fellowship
And all of you,
Who have provided a sanctuary here,
Where I finally feel safe enough to pursue a lifelong dream.
"In this season of rebirth,
I have begun to be reborn
As a woman,
Which is what I've
always wanted to be.
"I don't know if I will be successful,
But already, early in my journey,
I have received more understanding and encouragement here
Than I ever thought possible.
"And that gives me great hope.
"And I thank you for that."
I sat down. My friend I'd asked to sit with me squeezed my hand. The woman on the other side of me, who hadn't known ahead of time, squeezed my other hand.
After the service, lots of people came to me and wished me well. Others kind of avoided me, or so it seemed, perhaps taking a little longer to come to terms with the announcement.
Overall, it went
very well. I think the keys were the support of the minister and friends, and being completely prepared. I didn't go to church dressed in women's clothes for another few weeks, and when I did I dressed very much as any other woman my age would wear to my church.
This worked for me. Your results may vary.
