I could begin this lecture with many topics: with the first lines of the Nicene Creed or with any catechism textbook. However, before touching on these matters, I want to start with the meaning of the Church itself. This may sound simple, even childlike, but everything important begins with
something simple.
“I believe… (The Nicene Creed)… in one, holy, catholic, and apostolic
Church.”
As we see, this is a matter of faith, because the words begin with “I believe.”
It is not something that comes only from daily experience. There are many
differences and divisions in the Christian world, yet we say that the Church is one.
There are many sins and even persecutions among people, but the Church is still
one. Both in priestly life and in ordinary human life, we see many weaknesses, and
still we believe in the holiness of the Church. It is very difficult to connect today’s
Church directly with the Church of the Apostles, but even so, the Church that we
see with our own eyes—no matter how surprising it may seem—is still apostolic.
This, too, is a matter of faith.
Despite all these difficulties, the Church knows something deeper about
itself. So, what is the Church? In different languages, the word “church” has
different meanings. One meaning comes from the Greek expression kyriou oikos,
which means “the house of the Lord.” This refers mainly to the building, the
temple. From this meaning, we get the English word church and the German
Kirche.
But there is also another Greek word: ekklesia. In many catechetical books it
is translated simply as “assembly” or “gathering,” but this is not fully correct.
Ekklesia comes from the verb ek-kaleo, which means “to call out” or “to
summon.” It sounds almost like a challenge or a call. The word ek means “out.”
The Apostle Paul uses a related idea when he speaks about the “chosen people.”
From the same root we get words like elect and election. So, the Church is a
calling.
The Church is made of people who have heard a call and who realized that
they are strangers to what once seemed normal and natural. We hear a voice that
calls us. We do not fully understand this voice, but we hear it and we follow it in
order to understand it more deeply. At the same time, there are many people around
us who do not hear this voice at all. This is our spiritual community, the invisible
Church, which we cannot fully feel yet.
In the twentieth century there was Archbishop John of San Francisco, whose
name as a layman was Dmitry Shakhovskoy. He was a very interesting person:
handsome, a poet, a friend of Marina Tsvetaeva. He lived in emigration in France
and had his own journal. Suddenly, he left everything and went to Mount Athos.
One year later, when he explained why he became a monk, he said: “I became tired
of my own truth, and I wanted the Truth.” People like this—people who hear the
call—form the Church. This is who you are.
From here, we can better understand another word often used in Church life:
parish. This comes from the Greek word paroikia. The Greek prefix para appears in
many words. The word paroikos originally meant a person without a permanent
home, a stranger or foreign resident. From this word, in the first century, Saint
Ignatius of Antioch formed the idea of living “as a stranger.”
When Saint Ignatius was arrested in Antioch and taken to Rome, he wrote
letters to the Christians in the cities where he stopped on the way. This road is still
known as Via Egnatia. In his letters he begins with words like: “The Church of
God, which lives as a stranger in Corinth, in Ephesus, in Rome, in Smyrna.” This
was how early Christians felt. The Church means leaving the past behind and
beginning a new future. From here we get the word parish in English, prikhod in
Russian, and paroisse in French.
In English, the word church can also translate the Greek word used in the
Septuagint for the Hebrew qahal, which means an assembly. But this was not just
any gathering. It meant the chosen people. Not everyone living in Jerusalem or
Palestine could belong to it—only the descendants of Abraham who accepted the
Law of Moses. In ancient Athens, ekklesia also meant the assembly of citizens, and
not everyone had the right to participate. Because of this, the word always kept a
sense of being chosen.
We have spoken about the meaning of the word “Church.” Now imagine
modern radio stations that send signals through waves from special points. In the
same way, we need the right spiritual “frequency” to connect to God’s wave—that
is, to the Church.
,
Now let us speak about the attributes of the Church. The Church is one. It is
not one because we all vote together or smile nicely at each other. The Church is
one because it has one source. Its source, foundation, and head is Christ Himself.
The Church is born from above, from Christ. As Christ says to His apostles: “You
did not choose me, but I chose you.” The Church is not born from the earth; it
comes down from heaven, from the Lord, with His meaning and purpose.
This is clearly seen in Orthodox iconography. In Orthodox icons, figures are
not always drawn with perfect anatomy or natural proportions. Sometimes you see
long necks or unusual shapes of hands and bodies. These proportions may look
strange, but in the end, the icon appears harmonious. In early icon painting, the
painter first drew the outline and then filled it with details. This could cause some
distortion, but the final image was still harmonious.
The same is true of the Church. The unity of the Church is created and given
by Christ. Christ is the head, and we are the body. We enter into Christ’s outline
with our imperfect and unbalanced human forms.
In John 20:23, Jesus says to His disciples: “If you forgive anyone’s sins, their sins
are forgiven; if you do not forgive them, they are not forgiven.” What do these
words mean for the Church? To whom does Jesus say this, and why? Some say this
applies only to the apostles and their successors, the bishops. Others say it is said
to all Christians: what you do with your soul will reach heaven. This also sounds
logical.
However, Church history shows us that what happens on earth is not always
immediately confirmed in heaven. Two simple examples can be given. Saint
Nicholas of Myra was once removed from the priesthood at the First Ecumenical
Council. Those who know his life understand this story. According to tradition,
Christ and the Mother of God appeared and intervened, and his episcopal dignity
was restored. We may not have many historical documents, and the story may be
partly legendary, but it is meaningful.
Another example is Saint John Chrysostom, whose Divine Liturgy we
celebrate. He was removed from his position as bishop. Similar things happened
many times in Church history—in Georgia, Greece, Russia, and elsewhere. Even in
the twentieth century, there were anathemas in the Church.
Why do I mention this? Because the Church can visibly make mistakes. But
such decisions are not final judgments. God may not agree with them. Later, the
Church often re-examined these decisions, removed anathemas, restored people,
and even canonized them. This happened with Saint John Chrysostom. In the West,
we see the same with Joan of Arc, who was condemned and later canonized as a
saint.
God is more merciful than our human declarations. On Mount Athos and in
some Churches—such as in Georgia, Serbia, Russia, and Romania—Catholics and
Protestants are sometimes baptized again. This shows how seriously the Church
understands its calling, its unity, and its holiness. In America, however, we receive
people through chrismation, and this is also a Church tradition. I will not go deeply
into this topic now, because we will need to speak about the sacraments in detail
another time.
Now imagine this picture, and why the Church is important, why
understanding the true Church matters. From the early centuries, when debates and
conflicts began, churches opposed one another and separated from the true source.
As a result, people in later generations were born into these mistaken views, and
the earlier history became unknown to them.
Imagine that two Orthodox Christians argued, and one of them became
Catholic or Protestant. Then he founded a church, and the people living in that
region continued their religious life under his authority. They did not know what
had happened or what had changed. They liked their pastor and his teaching and
simply followed him blindly, without noticing much difference. Often, divisions
were caused by personal conflicts between individuals, not by the true essence of
faith itself.
There are mistakes—real theological mistakes—but they do not always
destroy a person’s spiritual life immediately. Saint Theophan said that Catholics
and Protestants are like people with sick lungs, like tuberculosis. A person with
tuberculosis is alive, not dead. The illness is serious, breathing is difficult, but life
is still there.
Dogma and canon law are not the same. The Church has dogma, and it also
has canon law. Dogma includes truths such as Christ being one and the Holy
Trinity. For example, if my finger is cut off—whether by accident or by choice—
that finger no longer belongs to my body. In the same way, a person who separates
from the Church, for any reason, cannot be part of the Church, just as a finger
cannot live apart from the hand.
The Church says that if for three weeks a person does not receive
Communion, that person is no longer living as a member of the Church and needs
repentance. At the same time, there are canonical rules. Saint Basil says that there
are different rules and different ways of receiving Christians into the Church, and
he admits that he does not fully understand why it happens this way. Still, he says
that he trusts the wisdom and decisions of his predecessors. These rules were not
created by us; they come from the Lord.
Canonically, the Church has used three ways of receiving people: baptism,
chrismation, and repentance. All three are valid and truly Christian. Outside the
Church, there is no salvation, and without the Church, there are no sacraments.
The Church recognizes three orders: bishop, priest, and deacon. The Church is not
holy because of us; the Church is holy because of Christ. The word “holy” itself
has a history. It originally meant “set apart,” “chosen,” or “separated” for a special
purpose. A holy cup was used for holy service. Holy land, holy Israel, holy service
—these were not called holy because the people were without sin. There were
sinners then, and there always will be. The meaning is that God has His own vision
for humanity: being chosen for a special service. This was the Old Testament
understanding.
In the New Testament, holiness receives a new meaning. What is holy is
what is purified by the Holy Spirit. In this sense, the Church is holy. But holiness
does not work automatically. The Church is holy, but this does not mean that every
Christian is holy.
During the Soviet period, the martyr Saint Valentina Sventsitskaya wrote:
“Every sin committed in the Church is a sin against the Church, but not a sin of the
Church.” I remember a book that I probably would not read again now that I try to
live more consciously as a Christian, though I still read all kinds of books for
analysis and growth. That book was The Decameron by Giovanni Boccaccio.
In The Decameron, there is a story set in Paris in the 14th century. Two
friends live there: one is French and Christian, the other is Jewish. The Christian
wants very much to convert his Jewish friend. One day they actually choose a date
for baptism. Suddenly, the Jewish man says he does not want to be baptized yet. He
wants to go to Rome first. He says he has heard many things about the Church
there—about bishops and priests—and wants to see everything with his own eyes.
The French friend knows very well that at that time many priests were not living
good lives, and that such a journey might harm his friend spiritually. He asks him
not to go. But the Jewish man insists and goes anyway. After six months, he
returns. The French friend no longer speaks about baptism, but the Jewish man
says: “When will I be baptized?”
The Frenchman is surprised and asks, “You want to be baptized? You were
in Rome? You saw the bishops? You saw the priests? You saw how they live?”
“Yes,” he answers.
“And still you want to be baptized?”
“Of course,” he says. “Priests may sometimes do things that damage the
Church, but the Church is still alive. That means the Church is from God, not from
them.”
This is exactly the point. The Church is holy because God is holy. The
Church is given by a testament, not by agreement. An agreement needs two sides,
and it can be broken if one side refuses to keep it. But a testament is given freely
by the one who leaves it. You cannot refuse it. Christ gave us His blood, His body,
His Church.
The Lord said: “I am with you always, until the end of the world.” What
does this mean? It means that He remains with us always—despite our falls,
despite our rejection of Him, despite our forgetting Him. In spite of everything, He
is with us.
There are many such stories in the Church. That is why Saint Ephrem the
Syrian writes: “Every Church is an ekklesia of the repentant. Every Church is a
Church of sinners.” There is strength, and there is weakness. Strength is when we
understand the true nature of the Church. Weakness is when we want to keep living
with our sins and do not plan to change anything.
The holy apostles were not tolerant of sin, but they were tolerant of the sinner—of
the repentant sinner. If this were not so, they would not have been killed
everywhere they went. People sometimes imagine that the Church is united
because everyone votes together at councils. But this is not true. Conciliarity and
democracy are not the same thing. Christianity cannot be a democratic religion,
simply because it is a revealed religion. It is not created by people; it is given by
God.
When we say that the Church or the bishops are successors of the apostles,
what do we mean? If we read the New Testament, especially the letters, we see that
Timothy and Titus were not mainly tasked with preaching like the apostles. Their
role was administrative and organizational. They supervised the Church. But we do
not see Peter or Paul saying to them: “Go now and continue my line of preaching.”
The apostle preaches, founds a Church, appoints a bishop, and then continues his
journey and his preaching.
