The fundamental mission of St. Leopold Mandić was serving the penitents in the sacrament of reconciliation and penance. He was a highly sought-after and respected confessor, who was always available to his penitents. He was very merciful when hearing someone’s confession. But, when necessary, he was a strict and righteous judge. He stood out as a wise confessor who dealt with his penitents according to God’s inspiration. By the gift of knowing the heart, he helped penitents the most to truly repent for the sins they committed. He prayed and did penance for his penitents so that the reparation for sins would be properly done. Faith was of great importance in his life. He was always devoted to the Blessed Virgin, and she helped him to resolve difficult situations. He set the Eucharist as the foundation of his life, from which he drew strength for his tireless service in the sacrament of reconciliation. The Eucharist led him toward confession, and confession led him toward the Eucharist. He lived according to the Eucharist in the manner in which, like Christ, he sacrificed himself for the salvation of souls. St. Leopold Mandić is very current today as a confessor. The example of his spirituality and the way of hearing confessions can nowadays serve many confessors as a model of an excellent confessor.
