On May 8 we will be celebrating the 148th anniversary of the establishment, by Mother Teresa Ewa Countess Potocki nee Sułkowski, of the first house of the Congregation of the Sisters of Our Lady of Mercy in Krakow. The sisters became involved in the education of girls and women in need of deep moral renewal, first in the „House of Mercy” at the Church of Divine Mercy at Smoleńsk street, and then in the convent at the crossroads of Zwierzyniecka and Straszewskiego (now occupied by Hotel Radisson). Since 1891, the convent’s house has been in Krakow-Łagiewniki. Today, the sisters are performing more than their original work, being also involved in the mission of St. Faustina to proclaim the message of Mercy to the world. They do this not only at the Shrine of Divine Mercy among the pilgrims from around the world, but also through many new works: the Association of Divine Mercy Apostles „Faustinum”, the publishing company „Misericordia”, the quarterly magazine „Orędzie Miłosierdzia”, the website available in 7 languages, the online broadcasts from the chapel of the miracle-famous Divine Mercy image and the tomb of St. Faustina, the perpetual Chaplet, the Chaplet for the dying, presence in the media, social networking, visits to parishes in Poland and abroad, participation in symposia and conferences devoted to the Mercy of God and the heritage of St. Faustina, meetings with young people in preparation for the World Youth Day in Krakow, correspondence, etc. Their ministry, even the most implicit, includes the proclamation of the message of the merciful Love of God to man.
