The Teaching of Blessed Michał Sopoćko about Truth and Worship of the Divine Mercy

The article deals with the teaching and scientific-journalistic activities of bl. Michael Sopocko to the apostolate for the truth about the mercy of God and the cult of the Divine Mercy. Bl. Michael inspired by the revelations of the mercy of God received by St. Faustina Kowalska, undertook the verification of these revelations, and then the apostolate of ideas and the cult of Divine Mercy. Over the decades, he has published a number of works which showed the truth about the mercy of God, represented the essence of the devotion to the Divine Mercy and justified the need for the introduction of the cult of Divine Mercy with a separate holiday. His works are presented in this article in chronological order, and their short presentation in terms of content. In the whole dissertation is shown an important and pioneering contribution of bl. Michael in the promotion of the cult of Divine Mercy since the very beginning. The teaching of the truth of God's mercy and explanation of the essence of the cult, together with motifs of the introduction are based on a solid biblical, theological, liturgical and pastoral foundation. This appears to be a unique role of bl. Michael Sopocko in spreading the cult of Divine Mercy in modern times, although not sufficiently understood and appreciated yet.
