Saeculo Exeunte Octavo §32

³² You have, and no doubt appreciate, that notable memorial of the solicitude of the Apostolic See for those to be trained properly for work in the sacred missions. It is the Portuguese Society for the Promotion of the Catholic Foreign Missions, which Our predecessor Pius XI encouraged. We strongly endorse it also. This does not mean that We trust less the works and zeal of the religious orders and congregations of both sexes because, in the course of the ages, the greatest number of missionaries came from them. For this reason We place Our great hope in these orders and congregations, as do the missionaries themselves. And since We know well the spiritual needs of the Portuguese colonies, We desire that others join in the missionary efforts. The local ordinaries indeed should cherish and protect them, so that the number of consecrated laborers grows daily.
