Pray for us on this, your feast day. From the collect of the Mass:

Oremus.

Tuórum corda fidélium, Deus miserátor, illústra : et, beátæ Elísabeth précibus gloriósis ; fac nos próspera mundi despícere, et cælésti semper consolatióne gaudére.

Let us pray.

Merciful Lord, we pray thee to pour the bright beams of thy grace into our hearts : that, by the glorious prayers of thy blessed Elisabeth ; we may learn to despise all worldly prosperity, and ever to rejoice in all heavenly consolation.
