St. Faustina Kowalska
Saint Faustina Kowalska, in her diary on Divine Mercy, wrote that Our Lord said to her: “I desire that the first Sunday after Easter be the Feast of Mercy. On that day the very depths of my tender mercy are open.” (Source: Divine Mercy in My Soul, 1987, Sister M. Faustina Kowalska)
Jesus emphasized to Saint Faustina that the depths of His Mercy were already open on that day, long before official recognition of the Feast by His Church. With the birth of Luisa Piccarreta on the day which would eventually be proclaimed the Feast of Divine Mercy, Jesus left a special sign of the unique importance of Luisa’s Mission, which her special confessor, Saint Annibale Maria Di Francia, described as “the triumph of the Divine Will in the entire universe.”
