The whole point of the Matthew zombies is to support Christianity's main theme (1 Corinthians chapter 15), which is that the dead will rise on Judgment Day and that Jesus proved it when he walked out of the tomb. The Matthew zombies were included to show that the dead will indeed rise. It's great propaganda. Notice that all of the dead didn't rise but only those who were "saints". Imagine if all of the dead in the entire Middle East had returned as zombies.
As I just wrote, the Matthew zombies are used to sell the idea of resurrection but in a way it invalidates the end game of Judgment Day when all of the dead will rise. All the Matthew zombies did was go visit their buddies. They didn't do anything worthwhile and they are nowhere to be seen now (or then).
Christianity doesn't work without zombies and ghosts. It doesn't work very well with zombies and ghosts either.
