Over the centuries, many different chaplets (series of prayers usually said on a string of beads) have been written to express devotion to a particular saint or to an aspect of the Christian faith. The Chaplet of the Divine Mercy is one of the most well-known chaplets. It is based on the visions received by Sister Faustina Kowalska, a Polish nun, in the 1930s. It is prayed to obtain Christ’s mercy and to bring mercy to others. The chaplet is usually prayed using rosary beads (and in fact the “Hail Mary” is one of the prayers of the chaplet), but its focus is on Christ and the promise of his mercy.
