In this series, from January 10 to 12 this year, there will be a retreat under the motto: “A Source of Hope in the Desert of the World.” The theme is the words of Jesus recorded in the “Diary”: “When you feel that your strength is fading, come to the Source of Mercy and refresh your soul, and you will not falter on the way” (Diary, 1486). Participants in these spiritual exercises are invited to discover that only the merciful God is the true source of hope and strength to overcome their weakness, all difficulties, and painful experiences. The retreat will be led by Father Dr. Michał Legan, a Pauline monk, Head of the Department of Media Theology at the Faculty of Social Sciences at the Pontifical University of John Paul II, Head of the Catholic Broadcast Editorial Office at Polish Television, and Sister M. Eliana Chmielewska from the Krakow community of the Congregation of the Sisters of Our Lady of Mercy, serving in the “Faustinum” association.
