Below is an extensive English summary of Hieromonk Eugenios’ Greek work Η ΕΝΝΟΙΑ ΤΟΥ ΜΟΛΥΣΜΟΥ ΤΩΝ ΟΡΘΟΔΟΞΩΝ ΕΚ ΤΗΣ ΕΚΚΛΗΣΙΑΣΤΙΚΗΣ ΚΟΙΝΩΝΙΑΣ ΜΗ ΚΑΤΑΔΙΚΑΣΘΕΝΤΩΝ ΑΙΡΕΤΙΚΩΝ — The Meaning of the Defilement of Orthodox Christians from Ecclesiastical Communion with Heretics Not Yet Condemned. The online posting identifies the work as dealing with the defilement of Orthodox Christians through communion with uncensured / not-yet-condemned heretics, and the downloadable PDF is listed under the same title on the Agiorites Pateres site.

General aim of the work

The book is written as an anti-ecumenist canonical-patristic study. Its central concern is the meaning of μόλυσμος, “defilement,” when Orthodox Christians remain in ecclesiastical communion with hierarchs or clergy who publicly teach heresy but have not yet been formally condemned or deposed by a council.

The work is not merely asking whether heresy is spiritually dangerous in an abstract sense. Its more precise question is this: what exactly happens ecclesiologically and sacramentally when one communes with a heretic before that heretic has been synodically judged?

The author presents the study as a corrective to two opposite errors. The first error is the view that defilement from communion with an uncondemned heretic means automatic loss of priesthood and loss of sacramental grace before formal deposition. The second error is the view that because no automatic loss of priesthood occurs before deposition, no real defilement exists and therefore separation from such a heretic is optional. In the author’s framing, both positions distort the patristic and conciliar evidence.

Method: Ecumenical Councils and consensus Patrum

The author explicitly grounds his method in the Acts of the Ecumenical Councils and the consensus Patrum, rather than in isolated patristic quotations. He argues that one must interpret particular passages from within the whole mind of the Church, not construct the whole doctrine from an isolated passage. He states that the infallibility of the Church is expressed through the Church as a whole, especially through Ecumenical Councils and the consensus of the Fathers.

This methodological point is important because the book is arguing against selective use of sources. The author believes that both rigorists and moderates sometimes take individual patristic phrases out of context. His stated approach is to examine how the Fathers and Councils actually treated heretical bishops in practice: whether they considered them already deprived of priesthood, whether they considered communion with them defiling, and when deposition took effect.

The author also treats the Councils of 879–880 under Saint Photios and 1341–1351 under Saint Gregory Palamas as ecumenical in ecclesial consciousness, even though he acknowledges that only seven Ecumenical Councils have been formally recognized in the usual official numbering.

The main thesis

The book’s thesis may be summarized as follows:

Communion with uncondemned heretics truly defiles Orthodox Christians, but this defilement does not mean that the uncondemned heretic has automatically lost the priesthood or that his mysteries have automatically become graceless before synodal deposition.

In the author’s terminology, defilement means participation in the heresy, condemnation, and schism of the heretic through ecclesiastical communion, not automatic ontological disappearance of priesthood before judgment. The author explicitly says that, according to the consensus Patrum, defilement is not to be understood as loss of priesthood in the way some rigorists claim, but as communion in the heretic’s heresy and ecclesiastical guilt.

This distinction is the key to the entire work. The author wants to preserve both principles:

1. Heresy defiles and communion with heresy must be avoided.
2. Deposition and loss of ecclesiastical rank occur by conciliar act, not automatically before judgment.

Thus, the book argues against the idea that the Mysteries of an uncondemned heretic are automatically invalid, but also against the idea that Orthodox Christians may safely or indifferently remain in communion with such a person.

Chapter A: The existence of defilement

The first chapter argues that defilement from communion with uncondemned heretics is attested in Scripture, the Ecumenical Councils, and the Fathers. According to the table of contents preserved in the online text, the chapter begins with “the existence of defilement from testimonies in Scripture, the Ecumenical Councils, and the Holy Fathers,” and then answers the objection that one who unites with condemned heretics does not lose priesthood without formal deposition.

The purpose of the chapter is foundational: before defining what defilement is, the author first establishes that such defilement exists. He is especially concerned with cases where the heretic has not yet been condemned. In his view, patristic practice does not allow the conclusion that no defilement exists merely because no council has yet deposed the heretical bishop.

The author’s argument is not that every association with a heretic has the same canonical consequence. Rather, he focuses on ecclesiastical communion: commemoration, liturgical communion, concelebration, and sacramental participation with those publicly teaching heresy.

Chapter B: Defilement and the subsistence of priesthood

The second chapter examines the relation between defilement and what the Greek text calls τὸ ἐνυπόστατο τῆς ἱερωσύνης, that is, the continuing concrete existence or subsistence of priesthood in a heretical cleric prior to deposition. The chapter studies this question through the Acts of several Ecumenical Councils, including the Third, Fourth, Sixth, Seventh, Eighth, and Ninth as the author numbers them.

The author’s conclusion is that the Fathers could regard heretical bishops as defiling, dangerous, and to be avoided, while still treating them as possessing priestly rank until formally deposed. This is especially important for the author’s rejection of the “automatic loss of priesthood” thesis.

The example of Nestorius is central. The author argues from the Acts of the Third Ecumenical Council that Nestorius was not treated as already automatically deposed from the moment he began preaching heresy. Rather, the Council summoned him, examined his teaching, judged it heretical, and then pronounced deposition. The author highlights that the Council speaks of making a decision against him and states that Nestorius was deposed on June 22, 431.

For the author, this proves that the heretical bishop’s deposition is a real ecclesiastical act, not merely a declaration that something had already happened invisibly or automatically. Yet before that deposition, communion with him was still understood as spiritually and ecclesiastically dangerous.

Chapter C: The meaning of defilement according to the Fifth Ecumenical Council and the Fathers

The third chapter is the conceptual heart of the book. It examines the meaning of defilement in light of the Fifth Ecumenical Council and the Fathers. The online text states that this chapter finds defilement to mean participation by knowingly communing Orthodox Christians in the heresy, condemnation, and schism of the uncondemned heretics. The author compares this to the principle of “communicating vessels”: communion transmits participation in the ecclesiastical condition of the one with whom communion is shared.

This is where the author most clearly distinguishes his position from a strictly sacramental-validity debate. He does not reduce defilement to the question, “Are the Mysteries valid or invalid?” Instead, he treats defilement as a matter of ecclesial participation and accountability. One who knowingly communes with a public heretic becomes implicated in that heresy, even if the heretic has not yet been formally deposed.

The author also examines patristic objections and passages often cited in the debate, including Saint John of Damascus and Athonite Fathers under Michael VIII Palaiologos, according to the contents shown in the online text.

Chapter D: “He who communes with the excommunicate is himself excommunicate”

The fourth chapter studies the principle:

ὁ κοινωνῶν ἀκοινωνήτῳ ἀκοινώνητος ἔστω

“He who communes with one out of communion, let him also be out of communion.”

The author argues that this principle applies not only to those already formally condemned, but also to those who are “ἀκατάκριτοι” or not yet judged, when they are nevertheless public heretics and therefore objectively outside Orthodox confession. The online text explicitly says the chapter concludes that this principle applies in the Fathers not only from a condemned “one out of communion,” but also from an uncondemned one.

This chapter is meant to show that the patristic tradition recognizes a real ecclesiastical contamination through communion, even before final synodal judgment. In other words, synodal judgment is necessary for deposition, but the faithful are not required to wait until final deposition before avoiding communion with manifest heresy.

This is also where the book’s practical anti-ecumenist thrust becomes clear. The author uses this principle to support the necessity of breaking communion with hierarchs who publicly teach Ecumenism.

Chapter E: Defilement and economy

The fifth chapter examines οἰκονομία, economy, and whether historical cases of temporary tolerance or reception of heretical clergy disprove the existence of defilement. The chapter studies seven economies, including cases connected with Saint Athanasius’ letter to Rufinianus, the father of Saint Gregory the Theologian, Nestorius, Theodore of Mopsuestia, the Monoenergists and Monothelites, Saint Theodore the Studite, and the Franks.

The author’s conclusion is that economy does not prove that defilement does not exist. On the contrary, he argues that economy presupposes the existence of a problem that is being temporarily managed. Economy is not a denial of canonical danger; it is a limited pastoral handling of that danger under specific historical conditions. The online introduction states that the author examined seven economies and concluded that economy confirms rather than denies the existence of defilement from communion with heretics under judgment.

This chapter is especially important because it prevents the book’s argument from becoming simplistic rigorism. The author recognizes that the Church has sometimes used economy toward persons involved in heresy. But he insists that economy must be bounded, purposeful, and temporary; it cannot become a permanent excuse for communion with heresy.

Chapter F: “The omitted matters”

The sixth chapter, titled Τὰ Παραλειπόμενα, “The omitted matters,” functions as a large appendix of related canonical and ecclesiological issues. According to the online table of contents, it includes sections on the Councils, their definitions and Acts, the meaning of deposition, the meaning of anathema, objections concerning the Lateran Council, the 1983 ROCOR anathema, which council deposes the Ecumenists, and the interpretation of the 15th Canon of the First-Second Council.

The chapter also includes extensive discussion of the 15th Canon of the First-Second Council, especially the phrase πρὸ συνοδικῆς διαγνώσεως, “before synodal judgment.” The author argues that this canon is not merely optional advice but expresses a binding patristic principle when the bishop publicly preaches heresy. The online text notes that the author is responding to the claim that treating defilement incorrectly leads some to view the second part of Canon 15 as optional.

The author also argues that ceasing commemoration of an uncondemned heretical bishop does not create schism when the separation is made because of the bishop’s heresy. Rather, the author’s position is that the heretic is the one introducing schism into the Church, while those who separate from his heretical teaching are preserving Orthodox communion.

Saint Basil and the distinction between healthy and diseased members

A major later section of the book treats Saint Basil the Great and his approach to heretics not yet condemned. The table of contents indicates that the author examines Saint Basil’s teaching on the existence of defilement, the relation of defilement to the subsistence of priesthood among heretics of his time, and Basil’s distinction between two flocks within the one Church: the healthy and the diseased.

The author uses Basil to argue that heresy creates a real wound within the visible ecclesiastical body before formal judgment. In this framework, there can be a diseased portion and a healthy portion, without implying that the Church herself has ceased to exist or that every cleric connected with the diseased portion has automatically lost ordination.

This is one of the book’s most important balancing points. It allows the author to say that uncondemned heretics are genuinely dangerous and defiling, while avoiding the conclusion that the Church has already vanished wherever such hierarchs remain administratively in place.

The book’s position on Canon 15 of the First-Second Council

The work strongly supports the use of the 15th Canon of the First-Second Council in cases of public heresy. The author argues that ceasing commemoration before synodal judgment is not schismatic when done because of publicly preached heresy. In the prologue to the online posting, Geron Savvas Lavriotis says the book explains why breaking communion with un-deposed Ecumenist heretics is obligatory, what defilement of mysteries means, how anathema and deposition are to be understood, and how Canon 15 is to be interpreted patristically.

The author’s own introduction similarly frames the dispute: if defilement is wrongly denied, Canon 15 becomes optional; if defilement is wrongly equated with automatic loss of priesthood, one falls into another error.

Thus, for the author, Canon 15 is the canonical expression of a deeper dogmatic and ecclesiological reality: Orthodox Christians must not remain in communion with publicly preached heresy, even before formal conciliar judgment.

The work’s anti-ecumenist application

Although the book is historical and patristic in structure, its immediate target is contemporary Ecumenism. Geron Savvas’ prologue explicitly describes the book as written for the struggle against Ecumenism and says it addresses the necessity of breaking communion with un-deposed Ecumenist heretics.

The author’s epilogue, according to the introduction, applies the conclusions to the pan-heresy of Ecumenism in the present age.

The work therefore functions as a canonical-theological defense of walling off from Ecumenist bishops, but with a specific qualification: the author does not argue that such bishops automatically lose priesthood or that their mysteries automatically become graceless before synodal judgment. Rather, he argues that communion with them nevertheless brings defilement understood as participation in their heresy and ecclesiastical guilt.

The book’s overall conclusion

The work’s final position can be condensed into several propositions:

1. Defilement from communion with heresy is real. It is not a metaphor with no ecclesiastical consequence.
2. This defilement applies even before formal synodal condemnation, when the heresy is publicly preached and knowingly maintained.
3. Defilement does not mean automatic loss of priesthood or automatic invalidity of Mysteries before deposition. Deposition is a formal ecclesiastical act, as shown especially in the case of Nestorius.
4. Communion transmits participation. Those who knowingly commune with uncondemned heretics participate in their heresy, condemnation, and schism.
5. Economy does not abolish the principle. Historical economies are exceptional pastoral measures, not evidence that communion with heresy is harmless.
6. Canon 15 of the First-Second Council is not merely optional when public heresy is being preached; it expresses the patristic obligation to separate from false teaching before synodal judgment.
7. The contemporary application is Ecumenism. The book is intended to justify and encourage the cessation of communion with hierarchs who publicly teach or participate in Ecumenism, while avoiding the claim that such persons are automatically deprived of priesthood before a council.

In short, the book tries to occupy a middle but still militant anti-ecumenist position: no communion with public heresy, but no private declaration of automatic loss of priesthood before synodal deposition.
