A good many Christian hymns and poems wander off unthinkingly in the direction of Gnosticism. The “just passing through” spirituality (as in the spiritual “This world is not my home, / I’m just a’passin’ through”), though it has some affinities with classical Christianity, encourages precisely a Gnostic attitude: the created world is at best irrelevant, at worst a dark, evil, gloomy place, and we immortal souls, who existed originally in a different sphere, are looking forward to returning to it as soon as we’re allowed to.
