One of the often ignored jewels of Gregorian Chant which came out of the decrees of the Second Vatican Council is the Graduale Simplex, or Simple Gradual. This is the Communion Antiphon for the Solemnity of Sts. Peter and Paul, which we celebrate this Sunday.
Tu es Petrus, et super hanc petram ædificabo Ecclesiam meam.
You are Peter, and upon this rock I will build my church
Tu es Petrus,
too ays PAY-troos
Thou art Peter
et super hanc petram
ayt SOO-payr hahnk PAY-trahm
and upon this rock
ædificabo Ecclesiam meam.
ay-dee-fee-KAH-boh ay-KLAY-see-ahm MAY-ahm
I-will-build Church mine.
