Cardinal Karol Wojtyła several times preached the homily during the annual pilgrimage of men to Our Lady of Piekary. Mystagogy was the key element in his speeches. Preaching the Word of God should be a reminiscence and a presentation of the work of Jesus Christ. The goal of preaching is to transform the life of each individual who listens to the word of God and to point him to all of the possiblities on how to answer to God in daily life. The listener should hear how his or her faith is going to resonate in the contemporary world. The content of mystagogical homilies of Cardinal Karol Wojtyła in Piekary was clearly seen in initation in the mysteries of faith and the rules of Christian life.
