This Sunday commonly called with us Low Sunday, has two names assigned to it in the Liturgy: Quasimodo, from the first word of the Introit; and Sunday in albis ( or more explicitly in albis depositis), because on this day the neophytes assisted at the church services attired in their ordinary dress. In the Middle Ages it was called Close--Pasch no doubt in allusion to its being the last day of the Easter Octave. Such is the solemnity of this Sunday that not only is it of Greater Double rite, but no feast, however great, can ever be kept upon it.

Ps. Rejoice to God our helper: sing aloud to the God of Jacob.
V. Glory, etc. As new-born etc.
