Policy #2: non-sacramental sharing:

Further, given the same principles, common participation by Catholics with their Eastern separated brethren in sacred functions, things and places is allowed for a just cause.(Agitur de s. d. communicatione in sacris extrasacramentali, Concilium est quod mitigationem concedit, servatis servandis.)

What might constitute a “just cause” in the experience of anyone involved in an East/West mingling? Remember that the issue of ecumenism with other Western traditions will be upcoming in our next Vatican II document.

    It is my understanding that if you are in Russia, and cannot find a RC Church, than it is acceptable to receive on Sunday at an Orthodox Church. This is true vice versa. Until an Orthodox Church was built in my community, there were two or three Greek Orthodox who received at RC Churches.

    But I seriously doubt a Russian Orthodox priest would administer communion to a stranger.

  3. Gavin says:

    Right, Eastern Orthodox do not allow non-Orthodox to commune, so far as I know. Rome DOES allow them to commune at a Mass, but they do not extend the same privelege to us.

    Well, there are places in western Greece and southern Italy where Catholic and Greek Orthodox pastors are more, shall we say, ecumenical with each other’s congregations. It’s an interesting remnant of the time when Greece was under the patriarchate of Rome (Greece only became part of the patriarchate of Constantinople in the 8th century, in the wake of disputes between Rome and the eastern emperors).

  5. For my part, and for the last 20 years, I’ve been singing at various Orthodox liturgies, vigils and other gatherings, at the invitation of Orthodox choir directors, and I have often invited Orthodox to sing with my choir and at my church. I personally think that this has done more to assist ecumenism in my small part of the world than all of the top-down gatherings for the last 40 years.

  6. Warm greetings in the True Christmas Spirit!

    I hope all is well, you seem very knowledgeable. I read through your blog/web site–very sharp indeed! Do you have a Doctorate in Divinity or Philosophy?

    Anyhow, I was wondering if you could give some priceless advice. I am thinking of buying a some good old Catholic theology books for some family members and loved ones, and well, I recently received an advertisement for this very interesting book called “Communicatio in Sacris: The Roman Catholic Church against Intercommunion of non-Catholics” by Mr. William J. DeTucci.

    I was wondering if you have seen any book review on this book? I could not find anything on the author. It seems the book talks about the Role of Vatican II in the Modern World and how some Traditionalists have resisted many of the Modernistic teachings of Ecumenism, Religious Liberty, and the New Mass, as opposed to the old Latin Tridentine Mass. However, I also recently read Benedict XVI’s Motu Proprio ( http://www.vatican.va), which seems to be give the Liberty of “Open Communion” to so-called Traditional Catholic Groups who dissent from Vatican II, i.e. Marcel Lefebvre’s SSPX, Mark Pivarunas’ CMRI, Clarence Kelly’s SSPV, Br. Michael Dimond’s Most Holy Family Monastery, the various Saint Benedict Centers, Jason Spadafore’s Raphael Society, Patrick Taylor’s Society of the Virgin Mary, and so many other Independent Bishops at Large)–all who promote Intercommunion Latin Mass Ritual, of course! I think the Spirit of Vatican II is really being recognized now by many of the Traditionalists who once followed Bishop Lefebvre in resisting Vatican II Conciliar Reforms, but since the Motu Proprio Latin Mass Ecumenism has been widely promoted and it has been “well received” by many of these same various Traditionalists Sects and also by many Liberal Bi-Ritual Bishops who offer both the Latin Mass and Ecumenical Modern Liturgies.

    However, breaking the rule of judging a book by its cover, and only peaking its table of contents, it seems to me this book is an itchy reaction to this Neo-Ecumenism that both Greek and Latin Churches have been involved with. Not sure if you have read the book, or know of some theologian who has written a review? Here is the link to the contents that I browsed:


    and also here:


    I would most greatly appreciate any book review that you or a theologian has done. This book seems to have positive merit in as much it claims to be “a Compendium of Roman Catholic Doctrine on the subject of Intercommunion with non-Catholics. This book produces the overwhelming theological consensus for the Dogmatic Teaching condemning Intercommunion with non-Catholics, putting together a treasury of Sacred Scriptures, Church Fathers, Doctors, Saints, Theologians, and Popes who have written on the matter.”

    However, I just wanted to verify that before I make my last minute shopping for this Christmas & New Year Season.

    May God bless you!

    Kind regards,


  7. Hello there,

    As the great Olympic Games are approaching, I was wondering what will Roman Catholics do in China to attend Liturgy Services? Will they attend the Patriotic Church that is in Schism from Rome, and commit Communicatio in Sacris?

    Well, this topic of Intercommunion with a Schismatic Sect really made me think.


    And then, the other day, I received this wonderful advertisement covering this topic from a TRADITIONAL Roman Catholic Theological position. I wanted to share this book with all Chinese people, but all tourists who may be going to the Summer Olympics and will be worried about going to MASS (Byzantine or Latin Tridentine, and any other Rite). Here is a clip about this Theological Opus Magnus:

    “Communicatio in Sacris is a Compendium of Roman Catholic Doctrine on the subject of Intercommunion with non-Catholics. This book produces the overwhelming theological consensus for the Dogmatic Teaching condemning Intercommunion with non-Catholics, putting together a treasury of Sacred Scriptures, Church Fathers, Doctors, Saints, Theologians, and Popes who have written on the matter. This book also covers the Theological Controversies, Scandals, and Hypocrisies of how so-called Traditionalist Catholics and pseudo-Orthodox have openly communicated in the sacred with those they consider the Heterodox and yet have tried to justify their actions. This book, not only reveals their crimes, but it opens the door for anyone to understand what the Roman Catholic Church has always taught on this subject, namely, that it is forbidden for Catholics to join non-Catholic Communion.”



    I hope Catholics – all Catholics – who wish to remain truly Christian will read this book and understand this Great Dogma on “Communicatio in Sacris” and this Schismatic Crisis in China and abroad.

    Sincerely in the Christ Child,

    Merry Christ’s Mass (Christmas)!

    A Catholic Wanderer

    P.S. I also wanted to wish all a very Happy New Year, and there is this site for Catholic Latin Books, and also Tridentine Liturgy Books. Hard to find in CHINA I AM SURE!!!! CHINA NEEDS TO EMBRACE THE LATIN WESTERN IDEAS BY READING GREAT BOOKS! Please share, and also we want to share our knowledge, but please share with others this knowledge, and we hope to learn from you all!!!!!!

    Enjoy & Peace!
