The Feast of Divine Mercy is celebrated on the Sunday after Easter, the Octave Day of Easter. The celebration of Divine Mercy Sunday is an opportunity to reflect on the theme of how God’s mercy can overcome sin and, as the Congregation for Divine Worship and the Discipline of the Sacraments states, “a perennial invitation to the Christian world to face, with confidence in divine benevolence, the difficulties and trials that mankind [sic] will experience in the years to come.”
