An autobiographical lecture at the Faculty of Social Sciences of The John Paul II Catholic University of Lublin, presents the genesis and evolution of my research projects in their tight connection with the ontology of development and educational achievements in science and school practice. It is an introspective and socio-historical insight into the emergence of ideas, the scope of my personal involvement in radical changes in pedagogy as science and practice from kindergarten to university professor. My works have been appreciated, among other things, by rewarding the third honorary doctorate honoris causa.

In this article the author shows the meaning of revelation to the faith and christian life, Church, the world and theology. In his light the author criticises the pluralistic theology of religion.
