Peccantem me quotidie

Fra Angelico, Penitent St. Jerome. Princeton University, c.1424

Peccantem me quotidie
et non penitentem,
Timor mortis conturbat me.

I sin every day
and am not penitent;
the fear of death upsets me:

Quia in inferno nulla est redemptio. 
Miserere mei, Deus, et salva me.

Because in hell there is no redemption.
Have mercy upon me, O God, and save me.

Deus, in nomine tuo salvum me fac,
et in virtute tua libera me.

O God, save me for Thy name's sake
and deliver me in Thy strength.
