75. We thought We should explain these matters to you in this encyclical letter, venerable brothers and beloved sons, to inform you of the reasons why the Apostolic See has for a long time felt that the laborious task of revising your Euchologion should be undertaken, and to make known to you the care, zeal and cautious reasoning with which the work was undertaken and brought to completion. No changes were made in the oldest and most authoritative euchologies; only what seemed to have been included in some more recent editions by the credulity or wickedness of some men was eliminated or emended. Everything was kept which could possibly be kept, and some benevolent interpretation was employed to save your Rite from any appearance of attack.

We do not doubt that all of this speaks of Our real love for you and of the love of the Apostolic See. We are also certain that you will understand how great Our zeal and concern is that you persevere firmly in holy union and that the wanderers be recalled one day by God's grace to the same union and the way of salvation. It is up to you to use this revised edition of the Euchologion and to see to it carefully that any new edition of it conforms in every point to this edition, which has been published in 1754 at the press of the Congregation for the Propagation of the Faith. This will ensure that all the errors and nonsense which formerly found their way into and spoiled other editions will be kept out.

Finally We ask you to assist Us by your prayers in Our difficult task of governing the universal Church and We lovingly impart to you Our Apostolic blessing.

Given at Rome in St. Mary Major's on the 1st of March 1756 in the sixteenth year of Our Pontificate.
