Tu es Petrus
Tu es Petrus,
et super hanc petram aedificabo Ecclesiam meam,
et portae inferi non praevalebunt adversum eam.
Et tibi dabo claves regni coelorum.
Thou art Peter,
and upon this rock I will build my church,
and the gates of hell shall not prevail against it.
And I will give unto thee the keys of the kingdom of heaven.
Maurice Duruflé (b. 1902)
One of the most distinguished French organists and a respected though unprolific composer for his instrument.
