The article deals with the issue of using icons in catechetical biblical interpretation. The Baptism of the Lord icon can be used at the stage of theological understanding, which includes biblical, doctrinal, and liturgical context. The passages about St. John the Baptist and the Jordan River are important in the biblical context. St. John the Baptist is regarded as the lamp, the voice, and the friend of the bridegroom. He is also shown in relation to the prophet Elijah who was to come. As far as the doctrinal context is considered, John Paul II’s catecheses dealing with the baptism of Jesus in the Jordan River are important, along with the new Luminous Mysteries of the Rosary. The liturgical context points out the connection between the Feast of the Baptism of our Lord and the Epiphany. The article, coming within the range of material catechetics, is intended mainly for the researchers in the field of catechetics who are interested in programming of catechesis.
