JLC:
Take note of “ut unum sint”. This is the very title of an encyclical by John Paul II and he directly promotes this previously condemned error.
To begin with, I too think that the “ecuminical effort” presently underway in the Church is misguided and that the methods need serious reconsideration. However, I feel that your position regarding the heresy of JPII in relation to the declarations of Mortalium Animos is in error. To begin with, you only quote a small section of the document and seem to focus on the phrase “Ut Unum Sint” as if this is some kind of PROOF of your position.
Mortalium Animos
5.Admonished, therefore, by the consciousness of Our Apostolic office that We should not permit the flock of the Lord to be cheated by dangerous fallacies, We invoke, Venerable Brethren, your zeal in avoiding this evil; for We are confident that by the writings and words of each one of you the people will more easily get to know and understand those principles and arguments which We are about to set forth, and from which Catholics will learn how they are to think and act when there is question of those undertakings which have for their end the union in one body, whatsoever be the manner, of all who call themselves Christians.
7.And here it seems opportune to expound and to refute a certain false opinion, on which this whole question, as well as that complex movement by which non-Catholics seek to bring about the union of the Christian churches depends. For authors who favor this view are accustomed, times almost without number, to bring forward these words of Christ: “That they all may be one… And there shall be one fold and one shepherd,”[14] with this signification however: that Christ Jesus merely expressed a desire and prayer, which still lacks its fulfillment. For they are of the opinion that the unity of faith and government, which is a note of the one true Church of Christ, has hardly up to the present time existed, and does not to-day exist. They consider that this unity may indeed be desired and that it may even be one day attained through the instrumentality of wills directed to a common end, but that meanwhile it can only be regarded as mere ideal. They add that the Church in itself, or of its nature, is divided into sections; that is to say, that it is made up of several churches or distinct communities, which still remain separate, and although having certain articles of doctrine in common, nevertheless disagree concerning the remainder; that these all enjoy the same rights; and that the Church was one and unique from, at the most, the apostolic age until the first Ecumenical Councils. Controversies therefore, they say, and longstanding differences of opinion which keep asunder till the present day the members of the Christian family, must be entirely put aside, and from the remaining doctrines a common form of faith drawn up and proposed for belief, and in the profession of which all may not only know but feel that they are brothers.
- Let, therefore, the separated children draw nigh to the Apostolic See, set up in the City which Peter and Paul, the Princes of the Apostles, consecrated by their blood; to that See, We repeat, which is “the root and womb whence the Church of God springs,”[27] not with the intention and the hope that “the Church of the living God, the pillar and ground of the truth”[28] will cast aside the integrity of the faith and tolerate their errors, but, on the contrary, that they themselves submit to its teaching and government.
It is clear from these quotations that the error that is being condemned is not ecumenical efforts, but efforts to reduce the truth to only those doctrines that are currently held in common among all of the various Christian Churches. Ut Unum Sint does not advocate this view so you accusation that it promotes the error condemned by Mortalium Animos is incorrect.
