Rooted in Christian doctrine and biblical echoes, 'Passing and Glassing' can also be read as a spiritual allegory - The poem alludes to themes of vanity, human frailty, and divine constancy - ideas central to Rossetti’s religious beliefs - Rather than mourning transience, it ultimately gestures towards acceptance and wisdom, aligning human experience with scriptural truths - This interpretation sees the poem not as a lament but as a didactic piece, urging reflection on eternal truths beyond worldly appearances
