On Ecumenism:
"MORTALIUM ANIMOS
ENCYCLICAL OF POPE PIUS XI
ON RELIGIOUS UNITY
TO OUR VENERABLE BRETHREN THE PATRIARCHS, PRIMATES,
ARCHBISHOPS, BISHOPS, AND OTHER LOCAL ORDINARIES
IN PEACE AND COMMUNION WITH THE APOSTOLIC SEE.
Venerable Brethren, Health and Apostolic Benediction.
Never perhaps in the past have we seen, as we see in these our own times, the minds of men so occupied by the desire both of strengthening and of extending to the common welfare of human society that fraternal relationship which binds and unites us together, and which is a consequence of our common origin and nature. For since the nations do not yet fully enjoy the fruits of peace - indeed rather do old and new disagreements in various places break forth into sedition and civic strife - and since on the other hand many disputes which concern the tranquillity and prosperity of nations cannot be settled without the active concurrence and help of those who rule the States and promote their interests, it is easily understood, and the more so because none now dispute the unity of the human race, why many desire that the various nations, inspired by this universal kinship, should daily be more closely united one to another.
- A similar object is aimed at by some, in those matters which concern the New Law promulgated by Christ our Lord. For since they hold it for certain that men destitute of all religious sense are very rarely to be found, they seem to have founded on that belief a hope that the nations, although they differ among themselves in certain religious matters, will without much difficulty come to agree as brethren in professing certain doctrines, which form as it were a common basis of the spiritual life. For which reason conventions, meetings and addresses are frequently arranged by these persons, at which a large number of listeners are present, and at which all without distinction are invited to join in the discussion, both infidels of every kind, and Christians, even those who have unhappily fallen away from Christ or who with obstinacy and pertinacity deny His divine nature and mission. Certainly such attempts can nowise be approved by Catholics, founded as they are on that false opinion which considers all religions to be more or less good and praiseworthy, since they all in different ways manifest and signify that sense which is inborn in us all, and by which we are led to God and to the obedient acknowledgment of His rule. Not only are those who hold this opinion in error and deceived, but also in distorting the idea of true religion they reject it, and little by little. turn aside to naturalism and atheism, as it is called; from which it clearly follows that one who supports those who hold these theories and attempt to realize them, is altogether abandoning the divinely revealed religion.
- But some are more easily deceived by the outward appearance of good when there is question of fostering unity among all Christians.
Is it not right, it is often repeated, indeed, even consonant with duty, that all who invoke the name of Christ should abstain from mutual reproaches and at long last be united in mutual charity? Who would dare to say that he loved Christ, unless he worked with all his might to carry out the desires of Him, Who asked His Father that His disciples might be “one.”[1] And did not the same Christ will that His disciples should be marked out and distinguished from others by this characteristic, namely that they loved one another: “By this shall all men know that you are my disciples, if you have love one for another”?[2] All Christians, they add, should be as “one”: for then they would be much more powerful in driving out the pest of irreligion, which like a serpent daily creeps further and becomes more widely spread, and prepares to rob the Gospel of its strength. These things and others that class of men who are known as pan-Christians continually repeat and amplify; and these men, so far from being quite few and scattered, have increased to the dimensions of an entire class, and have grouped themselves into widely spread societies, most of which are directed by non-Catholics, although they are imbued with varying doctrines concerning the things of faith. This undertaking is so actively promoted as in many places to win for itself the adhesion of a number of citizens, and it even takes possession of the minds of very many Catholics and allures them with the hope of bringing about such a union as would be agreeable to the desires of Holy Mother Church, who has indeed nothing more at heart than to recall her erring sons and to lead them back to her bosom. But in reality beneath these enticing words and blandishments lies hid a most grave error, by which the foundations of the Catholic faith are completely destroyed.
