The bishops have delved into the procedure and the reasons for migrations, above all, by taking into consideration pastoral aspects. The study of ecclesial documents led them again to state that "the foreigner should not be seen as a threat or a problem", but should be "welcomed, first of all, as child of God, created in his own image, and thus owning inalienable dignity and rights". Single bishops’ conferences and dioceses are invited "to achieve a higher awareness of the presence and the difficulties of migrants of any kind", and to pay special attention "to refugees, migrating workers, women and students, who are often the most vulnerable". Therefore, the Churches are encouraged to appoint operators (chaplains, religious, etc.) for the pastoral care of migrants. "The immigrants they stated should be welcomed and respected, so as to encourage the spirit of brotherhood and mutual enrichment, which leads to collaboration among the people involved". Laymen, "busy with the things of the world", are also encouraged to take part "in the social, political, economical and cultural contexts". The two continental bodies (CCEE and SECAM) are committed to go on "studying and sharing experiences to the benefit of our populations, considering migrations ‘new room for evangelization and solidarity".” “
