Hi this is something that I had to do myself Today. I am a member of my Local church I live in the UK. I told a very close friend and the vicar of the church a few years ago and they where fine. I am still good friends with them.
However I have decided to come out to the whole church for a reason. Basically there was this young lady who liked me. So I decided it was best if I was upfront about being gay so no one got hurt. I also decided to let other people know.
I guess over the next few weeks I will find out how people take it. But everyone I spoke to seems to be ok by it and in some weird way it feels like a heavy load as been lifted off me.
