Ran the French through an internet translator, not sure if the French posted here is entire; because this is all I came up with:
Saint Pius X LETTER EX QUO NO NO (December 26, 1910) By a writing which is blamed on the question of the return of churches to Catholic unity Ever since the day, the decline of the ninth century, the nations of the East have begun to be torn down to the unity of the Catholic Church, it is difficult to tell the quantity of efforts which have been made by saints characters in order to bring in the breast of this Church the brothers dissidents. Over all, the Pontiffs, Our Predecessors, under the load they are filled to defend the faith and of ecclesiastical unity, have failed to stop any attempt by either paternal exhortation, or by official delegations or by solemn councils, the very schism that was fatal to the West a great sorrow and caused serious damage East. They testify to this concern, just to name a few, and Gregory IX, Innocent IV, Clement IV, Gregory X, Eugenius IV, Gregory XIII and Benedict XIV (the Constitution of our ad nuper March 16, 1743 prescribes a profession Special faith Orientals). But nobody knows with what eagerness generous in recent times, Our Predecessor of happy memory, Leo XIII, has invited all nations of the East to reunite the Roman Church. "For us, he says (Address If leaks in re, 13 December 1880, the Cardinals, Acta tome II, p. 179, see also the Apostolic Letters praeclara gratulationis of June 20, 1894, Acta t. XIV, p. 195 ) is a fact that even the memory of the very ancient glory of the East and the reputation of his services to mankind We are a charm. There, indeed, is the cradle of salvation of mankind that are the origins of Christian wisdom, that's where, as a plentiful river, flowed to the West the flow of all the benefits we received with the Holy Gospel ... By delivering our mind these considerations, we do not want and want nothing more than to give our care that throughout the East revive the virtue and greatness of their ancestors. And more so that the course of human events it leaves appear from time to time evidence to be hoped that the peoples of the East, long separated from the bosom of the Roman Church, will be reconciled one day, God willing, with her ".
It is certainly not least, you know, Venerable Brethren, We desire that makes us want to see soon shine on the day, subject to the wishes of so many eager devotees, which falls quite definitely the wall has long separated the two peoples, which, entwined in the embrace of one faith and charity, they will finally bloom again implored both peace and where there will be only one fold and one Pastor (John x, 16).
We were under the impression of these feelings when once, in a review of recent foundation, Roma e l'Oriente, appeared an article which caused us great grief. It was titled: "Thinking about the question of church union." The writing is full of so many and so serious theological errors, and even historical, it was difficult to earn more in fewer pages.
