To join the Church of Emacs, you need only say the Confession of the Faith three times :
“There is no system but GNU, and Linux is one of its kernels”.
Sainthood in the Church of Emacs requires living a life of purity–but in the Church of Emacs, this does not require celibacy (a sigh of relief is heard). Being holy in our church means installing a wholly free operating system–GNU/Linux is a good choice–and not putting any non-free software on your computer. Join the Church of Emacs, and you too can be a saint!
