Temporal resurrections do not save us, but instead direct us to look for life, even in death. Easter zombies and the like direct our attention to the ultimate promise given in Christ, and the implications of this promise for the whole world.
I know it’s a rite of pious holiday passage to complain about the commercialization of Christmas and to remind everyone to keep the “Christ” in Christmas. And don’t forget the secular “war on Christmas." Whatever.
