A Polish religious sister whose ordinary convent work accompanied a deep life of prayer, Faustina is remembered for her witness to Divine Mercy.
Faith in everyday work
Helena Kowalska was born on 25 August 1905 in Głogowiec, Poland, into a large farming family. Her schooling was brief. As a young woman she worked in domestic service, helping to support herself and her parents, while discerning a call to religious life.
In 1925 she entered the Sisters of Our Lady of Mercy and received the religious name Mary Faustina. Her assignments included cooking, gardening and welcoming people at the convent door. She lived in several communities, including Kraków, Płock and Vilnius. Behind these ordinary duties was a sustained life of prayer centred on Christ's mercy. She recorded her spiritual experiences in a diary and died in Kraków on 5 October 1938.
The message of mercy
John Paul II canonized Faustina on 30 April 2000. In his homily he connected her witness with the risen Jesus showing his wounds to the disciples and entrusting them with the ministry of forgiveness. He also announced that the Second Sunday of Easter would be called Divine Mercy Sunday throughout the Church.
The homily presents mercy as something received from Christ and then shared. Trust in God's compassion calls for compassion toward other people, rather than indifference to their needs. Faustina's remembrance therefore points beyond interest in extraordinary experiences toward a daily response of prayer, forgiveness and service. Her optional memorial was added to the General Roman Calendar in 2020 and is observed on 5 October, subject to the calendar's rules of precedence.

A moment for reflection
Name one worry that makes it difficult to trust God, and speak about it honestly in prayer. Then think of someone who needs mercy from you. A gentle answer, a sincere apology or practical help may be the next step. When reconciliation is difficult, ask for wisdom, patience and the support needed to act with both charity and truth.
