3 To ensure that the Eastern Christians who have seceded will return to the onetrue Church, it is necessary to provide them with an abundance of holy ministerswho, endowed with doctrine and piety, may persuade the others to accept thedesired unity. In addition, Catholic wisdom and life must be made known andimparted to them in such a fashion that it will fir their national charactercongenially. Therefore houses must be opened wherever expedient for the sacrededucation of the youth, a sufficient number of high schools should be available,distributed according to population. Their power of exercising each rite maythus be supplied with dignity. Genuine knowledge of religion, should be extendedto all by making the best literature available. You can easily understand thecosts of these and similar ventures. You also understand that the EasternChurches by themselves cannot meet all these expenses. Nor can We Ourselves inthese hard rimes offer the help We would like. Suitable aid must be askedprincipally from the Society for the Propagation of the Faith which We have justnow praised. Its purpose is entirely consonant with what We now have in mind.But lest apostolic missions, deprived in part of the aids by which they aresustained, suffer any harm, We must insist that the generosity of the Catholicstoward the Society become greater. It is fitting that a similar concern also beapplied to the Society for the Schools of the East whose growth We encouraged, especially since its directors have openly promised to contribute as much as possible for this worthy cause.
