5 This salutary work which We have long since commended to the zeal of thefaithful demands many others of similar scope. A great outlay is required toprovide for the education of missionaries, long journeys, constructingbuildings, erecting churches, and teaching, as well as for other similarnecessities. These expenses must be borne for some years, until the heralds ofthe gospel can establish themselves and take responsibility for their ownfinancial affairs. We hope that We have enough strength to undertake such a project. When serious difficulties obstruct Us, We turn to you, venerable brother, and the other bishops, as well as all Catholics. We commend such a holy and salutary work to your love and to theirs. We desire that everybody participates; even if the collection is small, the burden spread among many people will make it lighter for all. Thus, the grace of Christ - for this concerns the spreading of His kingdom - might reach everybody and give everybody a share in peace, forgiveness of sins, and special gifts.
