What are the mainstream denominations (if any) of Christian atheists?

[Christian atheism](https://en.wikipedia.org/wiki/Christian_atheism) is the practice of following the teaching of the Christian bible, or Jesus, without believing in the existance of God or that Jesus is the son of God. Do Christian atheists have denominations, and if so, what are those denominations? I will accept *either* actual denominations of Christian atheists, or denominations of Christians who believe in God but who nevertheless have members who identify as Christian atheists, however, I am primarily interested in the former.
