Redemptoris Missio §79

⁷⁹ Cooperation is expressed above all by promoting missionary vocations. While acknowledging the validity of various ways of being involved in missionary activity, it is necessary at the same time to reaffirm that a full and lifelong commitment to the work of the missions holds pride of place , especially in missionary institutes and congregations. Promoting such vocations is at the heart of missionary cooperation. Preaching the Gospel requires preachers; the harvest needs laborers. The mission is carried out above all by men and women who are consecrated for life to the work of the Gospel and are prepared to go forth into the whole world to bring salvation. I wish to call to mind and to recommend this concern for missionary vocations . Conscious of the overall responsibility of Christians to contribute to missionary activity and to the development of poorer peoples, we must ask ourselves how it is that in some countries, while monetary contributions are on the increase, missionary vocations, which are the real measure of self-giving to one's brothers and sisters, are in danger of disappearing. Vocations to the priesthood and the consecrated life are a sure sign of the vitality of a church.
