26. A particular thought goes to the lands of the diaspora where many faithful of the Eastern Churches who have left their countries of origin are living in a mainly Latin environment. These places, where peaceful contact is easier within a pluralist society, could be an ideal environment for improving and intensifying cooperation between the Churches in training future priests and in pastoral and charitable projects, also for the benefit of the Orientals' countries of origin.

I particularly urge the Latin Ordinaries in these countries to study attentively, grasp thoroughly and apply faithfully the principles issued by this Holy See concerning ecumenical cooperation(⁶⁵) and the pastoral care of the faithful of the Eastern Catholic Churches, especially when they lack their own hierarchy.

I invite the Eastern Catholic Bishops and clergy to collaborate closely with the Latin Ordinaries for an effective apostolate which is not fragmented, especially when their jurisdiction covers immense territories where the absence of cooperation means, in effect, isolation. The Eastern Catholic Bishops will not neglect any means of encouraging an atmosphere of brotherhood, sincere mutual esteem and cooperation with their brothers in the Churches with which we are not yet united in full communion, especially with those who belong to the same ecclesial tradition.

Where in the West there are no Eastern priests to look after the faithful of the Eastern Catholic Churches, Latin Ordinaries and their co - workers should see that those faithful grow in the awareness and knowledge of their own tradition, and they should be invited to cooperate actively in the growth of the Christian community by making their own particular contribution.
