15. The Council clearly highlighted the need in our day for harmonizing the strengths deriving from the interchange of prudence and experience within the Episcopal Conference, since “Bishops are frequently unable to fulfill their office suitably and fruitfully unless they work more harmoniously and closely every day with other Bishops”.(⁶²) It is not possible to give an exhaustive list of the issues which require such cooperation but it escapes no one that issues which currently call for the joint action of Bishops include the promotion and safeguarding of faith and morals, the translation of liturgical books, the promotion and formation of priestly vocations, the preparation of catechetical aids, the promotion and safeguarding of Catholic universities and other educational centres, the ecumenical task, relations with civil authorities, the defence of human life, of peace, and of human rights, also in order to ensure their protection in civil legislation, the promotion of social justice, the use of the means of social communication, etc.
