As long as you eat the transmogrified flesh, you get to be a zombie too, at some point (the last day), no matter your sins in life...well as long as you give all your wealth away first (preferably to the Church but if you give it in a way that brings more people that's okay too). The institution just gives you an opportunity to start the process during life as a gentle precursor to what comes after death.

Not to mention, the word "christian" was originally meant as an insult. So offensive.

It still kind of is?

Like that old wise crack: "Which part of my story gives you the impression I like crosses? So much that you use one as a symbol for me...?!?!?!"
