And if you decide to sing “St. Patrick’s Breastplate,” don’t forget to include the verses most hymnals omit:

Against the demon snares of sin,
The vice that gives temptation force,
The natural lusts that war within,
The hostile men that mar my course;
Or few or many, far or nigh,
In every place and in all hours,
Against their fierce hostility
I bind to me these holy powers.

Against all Satan’s spells and wiles,
Against false words of heresy,
Against the knowledge that defiles,
Against the heart’s idolatry,
Against the wizard’s evil craft,
Against the death wound and the burning,
The choking wave, the poisoned shaft,
Protect me, Christ, till Thy returning.
