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:
- Heresy defiles and communion with heresy must be
avoided.
- 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:
- Defilement from communion with heresy is real.
It is not a metaphor with no ecclesiastical consequence.
- This defilement applies even before formal synodal
condemnation, when the heresy is publicly preached and knowingly
maintained.
- 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.
- Communion transmits participation. Those who
knowingly commune with uncondemned heretics participate in their heresy,
condemnation, and schism.
- Economy does not abolish the principle.
Historical economies are exceptional pastoral measures, not evidence that
communion with heresy is harmless.
- 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.
- 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.
