We consider too that a further reason for this very frequent divorce between faith and practice in Christians is an inadequate education in Christian teaching and Christian morality. In many places the amount of energy devoted to the study of secular subjects is all too often out of pro portion to that devoted to the study of religion. Scientific training reaches a very high level, whereas religious training generally does not advance beyond the elementary stage. It is essential, therefore, that the instruction given to our young people be complete and continuous, and imparted in such a way that moral goodness and the cultivation of religious values may keep pace with scientific knowledge and continually advancing technical progress. Young people must also be taught how to carry out their own particular obligations in a truly fitting manner.65Cf. John XXIII's encyclical letter Mater et Magistra, AAS 53 (1961) 454.
In this connection We think it opportune to point out how difficult it is to understand clearly the relation between the objective requirements of justice and concrete situations; to define, that is, correctly to what degree and in what form doctrinal principles and directives must be applied in the given state of human society.
The definition of these degrees and forms is all the more difficult in an age such as ours, driven forward by a fever of activity. And yet this is the age in which each one of us is required to make his own contribution to the universal common good. Daily is borne in on us the need to make the reality of social life conform better to the requirements of justice. Hence Our sons have every reason for not thinking that they can relax their efforts and be satisfied with what they have already achieved.
What has so far been achieved is insufficient compared with what needs to be done; all men must realize that. Every day provides a more important, a more fitting enterprise to which they must turn their hands—industry, trade unions, professional organizations, insurance, cultural institutions, the law, politics, medical and recreational facilities, and other such activities. The age in which we live needs all these things. It is an age in which men, having discovered the atom and achieved the breakthrough into outer space, are now exploring other avenues, leading to almost limitless horizons.
