Why wait until after New Years?
I'm confused as to why you are going to Church in the first place. Is it to hear the message? Or is it more of a social thing? Are you going to Church to meet a lady and potentially marry her?
Churches are strange in a way. Even though they are all using the same Bible, some are accepting of transgender people while others believe it's a sin.
I think if you want to come out as transgender and marry a woman you meet at Church, you should shop around for a Church that's transgender friendly.
