On 24th December, 1894, Pope Leo XIII issued his Encyclical Letter Christi Nomen regarding the Propagation of the Faith and the Eastern Churches:
"3. To ensure that the Eastern Christians who have seceded will return to the one true Church, it is necessary to provide them with an abundance of holy ministers who, endowed with doctrine and piety, may persuade the others to accept the desired unity. In addition, Catholic wisdom and life must be made known and imparted to them in such a fashion that it will fit their national character congenially. Therefore houses must be opened wherever expedient for the sacred education of the youth, a sufficient number of high schools should be available, distributed according to population. Their power of exercising each rite may thus be supplied with dignity. Genuine knowledge of religion, should be extended to all by making the best literature available. You can easily understand the costs of these and similar ventures. You also understand that the Eastern Churches by themselves cannot meet all these expenses. Nor can We Ourselves in these hard times offer the help We would like. Suitable aid must be asked principally from the Society for the Propagation of the Faith which We have just now 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 are sustained, suffer any harm, We must insist that the generosity of the Catholics toward the Society become greater. It is fitting that a similar concern also be applied 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."
