The fear of coming out to my church has been on my mind a lot today, so I thought I would seek some more advice on here. I already received some good advice from a friend who is going through seminary about this. Basically, he said to talk first to the pastor in private to find out if he is supportive. He said to mention what is going on and ask if the pastor would support me and if the congregation would support me. If any answer to my questions is no, I should leave the church immediately.
I'm first trying to work up the courage to ask about these things. I'm also trying to figure out when the best time is to do this. I'm still pre-transition, so I figure that I can wait until up to the point where I start transitioning. I have another week before my first therapy appointment which means I have at least 3 months before I start taking hormones. Am I right to wait until I start hormones to have this discussion or should I do it as soon as possible to know right away if it is going to be against my best interests to stick to my current church (which is Methodist, in case that information could help with any advice).
I've also been very afraid of the reaction that I will receive from the religious community when I come out publicly as trans. I've been fortunate so far in finding support from my closest friends but I really fear losing my church community. Also, the fact that I play piano for the church could make this extra difficult. I'm someone who the congregation looks up to and I really fear the worst possible reaction out of this ordeal. Also, music has always been a part of me which I don't ever want to have to give up. No, I can't keep a piano in my apartment

I'm also afraid that even though I already have support through this that I'm going to take the first amount of condemnation very personally. I struggled for years with accepting myself as being trans, often praying that God would take these feelings away from me because I felt like an abomination.
