Thinking about it, what makes Ordet stand out (at least in comparison to what I've seen) is how "realistic" (for lack of a better term) it feels. It seems very this-wordly. Other directors with a penchance for theology like Bergman, Tarkovsky or Parajanov seems to make films that to various degrees feel more other-wordly. Or engage in some deep psychological exercise, which also removes the narrative from a more tangible real-life setting.
Christianity is inherently a metaphysical religion. There exists two planes. The spiritual realm and the wordly realm. Directors therefore tend to imbude their films with metaphysicals settings/characters/events in the real world, and therefore making them feel more "other-wordly".
I'm talking about stuff like: Death in Seventh Seal, the deep discussions in Persona, The Zone in Stalker, or how Pomegrantes is filmed like if you're watching a series of icons. And so on with the examples.
In a way, Ordet feels to me like a more purebreed film. It's the religious movie most squarely set in our world. It's squarely about faith. Johannes may be a living Christ, yet his character feels so "this-wordly".
All of this gives Inger's bodily resurrection a more direct impact. The fact that Stalker's child has telekinetic powers or that Kris meets his father in the ending of Solaris feels very diegetic because both films where thoroughly imbued with elements that feelt metaphysical. Yet in Ordet we never encounter anything that feels
that metaphysical. Inger's resurection therefore feels more wordly, more set in our plane of existence rather then gifted from some abstracted metaphysical realm. The living Jesus exists squarely in our world.
Yeah I have no idea where I'm going with this.
