59 Therefore, in order that the demands of justice may be met, and attempts to achieve this goal may succeed, what is needed is the gift of grace, a gift which comes from God. Grace, in cooperation with human freedom, constitutes that mysterious presence of God in history which is Providence. The newness which is experienced in following Christ demands to be communicated to other people in their concrete difficulties, struggles, problems and challenges, so that these can then be illuminated and made more human in the light of faith. Faith not only helps people to find solutions; it makes even situations of suffering humanly bearable, so that in these situations people will not become lost or forget their dignity and vocation. In addition, the Church's social teaching has an important interdisciplinary dimension. In order better to incarnate the one truth about man in different and constantly changing social, economic and political contexts, this teaching enters into dialogue with the various disciplines concerned with man. It assimilates what these disciplines have to contribute, and helps them to open themselves to a broader horizon, aimed at serving the individual person who is acknowledged and loved in the fullness of his or her vocation. Parallel with the interdisciplinary aspect, mention should also be made of the practical and as it were experiential dimension of this teaching, which is to be found at the crossroads where Christian life and conscience come into contact with the real world. This teaching is seen in the efforts of individuals, families, people involved in cultural and social life, as well as politicians and statesmen to give it a concrete form and application in history.
