Misericordia

The Third Sunday of Easter is the day that occurs two weeks after the Christian celebration of Easter. Western Christianity In the traditional Roman Rite of the Catholic Church, this day is officially the Second Sunday after Easter, also known as Misericordia Sunday and Good Shepherd Sunday. "Misericordia Sunday" is due to the incipit ("Misericórdia Dómini") of the introit assigned to this day's liturgy. The full text of the introit in Latin is: "Misericórdia Dómini plena est terra, allelúia: verbo Dómini caeli firmáti sunt, allelúia, allelúia. Exsultáte, iusti, in Dómino: rectos decet collaudátio." This introit is based on verses 5, 6, and 1 of Psalm 33. "Good Shepherd Sunday" is due to the Gospel reading assigned to it. In the 1970 revision of the Roman Missal, this day was designated the "Third Sunday of Easter." The "Misericórdia Dómini" introit for this Sunday was swapped with that of the following Sunday, and the "Good Shepherd" Gospel reading was likewise moved forward one week.
