This Sunday is the 2nd Sunday after Paschal Sunday which is commonly called Good Shepherd Sunday in the Extraordinary Form since all of the propers revolve around the traditional devotion to Christ as the Good Shepherd. These are also the Latin Propers for the 4th Sunday of Paschaltide in the Ordinary Form (also known as Good Shepherd Sunday).
