The Institute of Divine Mercy's mission is strictly connected with Blessed Fr. Michael Sopoćko's mission and Jesus's proclamation of Divine Mercy received by Saint Faustina Kowalska.

The idea of Divine Mercy - as the Institute's foundation - is fulfilled by consecration and laity at the same time.

Our aim is to worship Divine Mercy with prayer, consecrated life and deeds of mercy; as well as to proclaim and promote the worship of Divine Mercy in the environment in which we live and work. (IDM Constitution, Art. 9)

The essential means to carry out the task are the vows to live by the evangelical counsels, prayer and the Eucharist. Being close to Virgin Mary - Mother of Mercy - is vital for our spiritual life.

In response to Jesus's merciful love, we strive to establish a personal, heartfelt and self-denying bond with Jesus by carrying out the consecration vows as perfectly as possible and putting all our trust in Him, so that the invocation "JESUS, I TRUST IN YOU" would become a characteristic spiritual feature of all Institute's members. (IDM Constitution, Art. 15)

Our formation is based on the Bible, the Diary of Saint Faustina, Blessed Fr. Michael Sopoćko's writings as well as current Catholic Church documents. The Papal encyclicals and bulls of John Paul II's (Dives in Misericordia), Benedict XVI's (Deus Caritas Est) and Francis's (Misericordiae vultus) are of special importance.

Each member's life should be aimed at an apostolate carried out in the spirit of mercy which comes from her intense spiritual life. None IDM member can walk indifferently past someone either materially or spiritually in need but rather, following Merciful Jesus and driven by His love, she should do them good by deed, word or prayer. We trust that the good we do to someone is a true act of merciful love only when doing it we deeply believe that we also receive good from the person we help. (based on John Paul II, Dives in Misericordia).
