There aren't any, if so it's not intentional. Typically, those who feel they MUST find a connection will stretch things out until they make that connection. The walking dead is about survival for yourself and those closest to you; survival of the fittest. Neither of which is what Jesus tried to teach his disciples in the Gospel for example. I mean its not like you can 'save' a zombie, right? There are no christian connections to the WD

Just another case of some group trying to align themselves with pop culture.
Not when every other scene is shot in a church, and every 3rd line is about God, faith, belief, and some of the more weighted scenes (think Maggie and Glenn) are about faith and God.
If not directly to do with Christianity, there is definitely a push for a religious element on the show.
Re-watch some episodes and you will be surprised at how many references you see now that someone pointed it out..
