On February 22 it will be four years since the Congregation of the Sisters of Our Lady of Mercy started its ministry on Facebook, in our open group “Sanktuarium Bożego Miłosierdzia”. The project essentially involves proclamation of the message of Mercy and support religious formation by disseminating knowledge. The group has more than 18, 400 members. On this occasion, we would like to thank the Admins and all participants of the Group for their work. We pray for you all every day in the chapel with the miracle-famous image of Merciful Jesus and the tomb of St. Faustina. The Congregation has been present on Facebook since 2014 in preparation for the World Youth Day. We run three profiles for the young: Faustyna2016 (in Polish, English and Spanish), and the fan page of the Shrine of Divine Mercy associated with the website: www.krakow.faustyna.pl.
