As a body of the universal Church, it is also at the service of the local Churches. It maintains systematic contacts with Episcopal Conferences and their regional groupings and collaborates regularly with them. Through the Episcopal Conferences, or with their assent, the Pontifical Council likewise is in touch with a broad range of Church bodies on the national level that have been established to make the faithful aware of their responsibilities in the field of justice and peace. Some of these are primarily for study and reflection, while others are more action-oriented. They include national Justice and Peace Commissions or Commissions for Social Questions, movements for the defense of human rights or for the promotion of peace or development etc.
