It happens that a person simply does not want to be brought up. One of the basic resources of the Church in its educational ministry is catechesis. The author looks at the first phenomenon of conscience, and his ties to the truth and freedom (point 1), then the phenomenon of secularization of morality in Polish conditions (point 2), and finally catechesis, in the course of which is to pursue the formation of conscience (point 3). Thus, the analysis is carried out in various conventions of research: successively in the ethical, sociological and catechetical.
