58 We also wish to bestow particular praise on all members of the pontifical mission society who have undertaken the noble, if sometimes thankless, task of collecting funds in the Church's name, becoming, as it were, beggars for the newly founded communities of faithful in the mission fields, which afford the Church so much glory and hope. We congratulate these Our beloved sons from Our heart, just as We are happy to express Our best thanks to all those, likewise, who support the Society for the Propagation of the Faith with such alacrity. To the latter has been entrusted a gigantic task: namely, the promotion of missionary work in vast continents under the direction of Our dear son, the Cardinal Prefect.
