“I shall sing forever the Lord’s mercy” (Ps 89 [88]). This Sunday is popularly known as Divine Mercy Sunday. Between 1930 and 1938 Christ appeared to Sister Faustina, a Sister of Mercy in Poland who initiated the Divine Mercy devotion. She was canonized on April 30, 2000, the Sunday after Easter, the Feast of Divine Mercy. On Good Friday, 1937, Jesus requested that Blessed Faustina make a special novena before the Feast of Mercy, from Good Friday through the following Saturday. Jesus also asked that a picture be painted according to the vision of Himself as the fountain of mercy. He gave her a chaplet to be recited and said that it was appropriate to pray the chaplet at three o’clock each afternoon (the Hour of Great Mercy).
