Any way you slice it, it's the Second Sunday of Easter, the Octave Day of Easter. Easter and Christmas are the only two days left that have octaves (eighth days). At one time, Ascension had an Octave, and the Sunday following it was simply the "Sunday in the Octave of the Ascension". I'm sure there were more feasts with octaves out there at one point, but I'll save that for another discussion (or even save it for those more theologically inclined than I).
As stated in previous years, this Second Sunday of Easter is traditionally known as "Low Sunday", and even more liturgically known as "Quasimodo Sunday", after the beginning of the Latin Introit for this day: Quasimodo geniti infantes, alleluia, rationabiles, sine dolo lac concupiscite, alleluia, alleluia, alleluia (Like newborn babes, alleluia, crave pure spiritual milk, alleluia, alleluia, alleluia.). Then there is "Divine Mercy Sunday", as declared by Pope John Paul II in 2000.
MUSIC FOR HOLY MASS
Sung Ordinary of the Mass: Missa "Cristo Risusciti", by Luigi Picchi (the Mass setting we did at the Easter Vigil and on Easter Sunday)
Alleluia: from the chant O Filii et Filiae, which you may have heard in English as Ye sons and daughters. The melody originated in Paris in the late 15th century.
All numbers given are in the maroon hymnal ("The Hymnal"), except where noted.
Entrance hymn: Jesus lives, thy terrors now, #88
Psalm 118: Give thanks to the Lord for he is good; his love is everlasting, music by Owen Alstott (as written in the missalette under April 12)
