>>40472342 (OP)St Peter explicitly ruled that circumcision was not a pre-requisite for salvation.
Salvation is not something you achieve, it's not something you do for yourself. It's something Christ does for you because he loves you. That's literally it, mystery solved, accept Christ's love and get into heaven.
That said there are SOOO many parallels between the book of Acts and the modern plight of transgender people. Certainly my personal journey has matched St Paul's so closely that I can't help by feel a kind of kinship with him.
