107. If the proclamation of justice and peace is an integral part of the task of evangelization, it follows that the promotion of these values should also be a part of the pastoral programme of each Christian community. That is why I urge that all pastoral agents are to be adequately trained for this apostolate. "The formation of clergy, religious and laity, imparted in the areas of their apostolate, should lay emphasis on the social teaching of the Church. Each person, according to his state of life, should be specially trained to know his rights and duties, the meaning and service of the common good, honest management of public goods and the proper manner of participating in political life, in order to be able to act in a credible manner in the face of social injustices".211

As a body organized within the community and the nation, the Church has both the right and the duty to participate fully in building a just and peaceful society with all the means at her disposal. Here we must mention the Church's apostolate in the areas of education, health care, social awareness and in other programmes of assistance. In the measure that these activities help to reduce ignorance, improve public health and promote a greater participation of all in solving the problems of society in a spirit of freedom and co-responsibility, the Church creates conditions for the progress of justice and peace.
