The Divine Mercy Chaplet is a relatively recent but very popular devotion revealed by Our Lord to St. Maria Faustina Kowalska, a Polish nun. On Good Friday 1937, Christ appeared to Saint Faustina and asked her to recite this chaplet for nine days, starting on Good Friday and ending on the Octave of Easter (the Sunday after Easter Sunday), now known as Divine Mercy Sunday. In her diary, St. Faustina tells of Jesus’ great love and mercy for us when He told her, “Whoever will recite this prayer will receive great mercy at the hour of death”.

The chaplet is most often recited during those nine days, but it can be prayed at any time of the year, and Saint Maria Faustina recited it almost unceasingly.

A standard rosary can be used to recite the chaplet, and the entire devotion takes just 20 minutes—about the time it takes to pray the rosary.

Divine Mercy Sunday is April 8, 2018
