[Itaxpica]

Much of the Christian symbolism is just there for the sake of aesthetics, but this is less so true for the Jewish (and especially Kabbalistic) imagery - there's actually a lot of overlap between the plot of Evangelion and themes from Lurianic Kabbalah (especially the notion of the ein sof and the traditional interpretation of tikkun olam, which is reflected in the Human Instrumentality Project), so the visual/aesthetic nods to it are a nice touch.
