Today is Ash Wednesday, which marks the beginning of Lent. A popular saying to accompany the celebration of Ash Wednesday is taken from Gen 3.19, which reads, “For you are dust, and to dust you shall return.” Or, in Latin, quia pulvis es et in pulverem reverteris.
The Book of Common Prayer puts it this way for the burial service: Earth to earth, ashes to ashes, dust to dust. Terram terrae: cinerem cinere; pulverum pulveri.
And, somehow I think the saying would still be appropriate if you change ‘pulvis’ to ‘pelvis’, as more often than not man also comes from pelvis to pelvis.
