27 The drawbacks experienced by the few apostolic workers in the field are increased by their want of material means, which often approaches real poverty. Who will furnish these recently established missions with the generous financial backing they so urgently need? For they are situated, for the most part, in poverty-stricken districts which are, nevertheless, promising fields for the spread of the Gospel. The apostolic laborer is deeply grieved by his lack of so many things while the performance of so many tasks rests upon him. He does not need our admiration aiding the missions, if they are fully informed of the situation.
