Christian Church and the word church are used to
denote both a Christian association
of people and a place of
worship. The word is church usually, but not exclusively,
associated with Christianity.
The Christian Church is a religiously ambiguous
and cultural-sociological term to refer to all religions based on the worship
of Jesus of
Nazareth as the son of God. It is not a single
religious institution, neither a single faith. Today there is no
single political entity recognized by the secular world as the
unique Christian Church.
The Roman
Catholic Church and the Orthodox
Churches all claim to be the unique church established by Jesus
in the Great
Commission. Protestants on the other hand would hold that the
concept is justified by the notion that the Church is ultimately
headed by Jesus Christ himself, who acts as the unifying figure for
all who claim to follow him. Anglicans feel
that they are but a branch of the
Church. The term means something quite different for each
religious institution that sees itself as belonging to the
Christian traditions.
The phrase The Church in its widest sense, as the
Body of Christ has a similar breadth.
Etymology of church
The English language word "church" developed from Old English cirice, from West Germanic kirika, from Greek kyriake (oikia) "Lord's (house)", from kyrios "ruler, lord." The Greek word kyriakon (an adjective meaning "of the Lord") was used of houses of Christian worship since c.300, especially in the East, though it was less common in this sense than ekklesia or basilike. An abbreviation of ekklesia kyriake used in the septuagint to mean congregation of the lord.Terminology
Through history there have been various terms
that have been used to express the concept of a united Christian
Church. This section discusses some of these.
The English word church derives from the Greek
κυριακή (kyriake), "Lord's (house)". The term has expanded over
time to the allow today's more general meanings.
The Greek/Latin
word εκκλησια/ecclesia, literally "assembly" in Greek, is the
traditional Roman
Catholic/Orthodox term
referring to the Christian Church. Most Romance
languages use derivations of this word. This Latin word is
sometimes used in English as well.
The phrase One, Holy, catholic and Apostolic
Church appears in the Nicene Creed
() and, in part, in the Apostles'
Creed ("the holy catholic church", ἁγίαν καθολικὴν ἐκκλησίαν).
The phrase is intended to set forth the four marks, or identifying
signs, of the Christian Church — unity, holiness,
universality, and apostolicity — and is based on the
premise that all true Christians form a single united group founded
by the apostles.
The terms orthodox Church and orthodox
faith (not to be confused with the modern term "Eastern Orthodox"
with a capital 'O') have been used to distinguish what is
considered the true Church from groups considered heretical. The term
became especially prominent in referring to the doctrine of the
Nicene
Creed and, in historical contexts, is often still used to
distinguish this first "official" doctrine from others.
The term body of
Christ (cf. Bible verse 1|Cor|12:27|NAB), also known as the
Bride of Christ, is used to refer to the total community of
Christians seen as interdependent in a single entity headed by
Jesus
Christ.
The phrase Church Militant and Church Triumphant
(Ecclesia Militans, Ecclesia Triumphans) is used to express the
concept of a united Church that extends beyond the earthly realm
into Heaven. The term Church Militant comprises all living
Christians while Church Triumphant comprises those in Heaven. Within the
Roman
Catholic Church there is also the concept of Church Suffering,
or Church Expectant, comprising those Christians in
Purgatory.
The term Communion of Saints expresses the idea
of a shared faith which, through prayer, binds all Christians
regardless of the physical separation or separation by death. In
Roman Catholic theology this would be differentiated from the
Church Militant and Church Triumphant alone because it also
includes the Church Suffering.
History
The Christian Church originated in Roman
Judea in the first century AD, founded on the teachings of
Jesus of
Nazareth
believed by all Christians to be the Messiah, or
deliverer king, of the Jewish people. The
precise start of the Church is considered to be at Pentecost, but it
is usually thought of as originating with Jesus' Apostles.
According to scripture
Jesus commanded
the Apostles to spread his teachings to all the world.
Although springing out of the first century
Jewish
faith, from its earliest days some
sects of the Church accepted non-Jews without requiring
them to adopt Jewish customs (e.g.
circumcision), running counter to tradition. Conflict with
Jewish religious authorities quickly led to the expulsion of the
Christians from the synagogues in Jerusalem,
see also Council
of Jamnia.
The Church gradually spread through the Roman Empire
and outside it gaining major establishments in cities such as
Jerusalem,
Antioch,
and Edessa.
Christianity became a widely persecuted religion,
hated by the Jewish authorities as a heresy, and by the
Roman authorities because, like Judaism, its monotheistic teachings were
fundamentally foreign to the traditions of the
ancient world, as well as a challenge to the imperial
cult. Despite this the Church grew rapidly until finally
legalized and then promoted by Emperors Galerius and
Constantine
in the fourth century. A major controversy as the Church was being
formalized
was the Arianism vs.
Trinitarianism
debate which occupied the Church during the fourth
century. This period would begin the long-term persecution of
pagans and "heretical"
Christians in the Empire and the kingdoms that followed. See also
Christendom.
The Church of the Roman Empire was divided into
Patriarchal Sees with five holding particular prominence, one in
the West
(Rome), and
the rest in the East
(Constantinople,
Jerusalem,
Antioch,
and Alexandria). The
bishops of these five
would become the Patriarchs of the
Church. Even after the
split of the Roman Empire the Church remained a relatively
united institution (excluding Oriental
Orthodoxy and some other groups which separated from the rest
of the Church earlier). The Church came to be a central and
defining institution of the Empire, especially in the East. In
particular, Constantinople
would come to be seen as the center of the Christian world, owing
in great part to its economic and political power.
Once the Western
Empire fell to
Germanic
incursions in the 5th century, the (Roman) Church for centuries
became the primary link to Roman
civilization for Medieval
Western
Europe and an important channel of influence in the West for
the Eastern
Roman, or Byzantine, emperors. While, in the West, Christianity
struggled as the so-called orthodox (i.e. Roman) Church
competed against the Arian Christian
and pagan faiths of the
Germanic rulers, the Eastern Romans spread Christianity to the
pagan Slavs
establishing the Church in what is now Russia, Central
Europe and Eastern
Europe. The reign of Charlemagne in
Western Europe is particularly noted for bringing the last major
Western tribes outside of the Church into communion with Rome, in
part through conquest and forced conversion.
Starting in the 7th century the Islamic
Caliphates rose and gradually began to conquer larger and
larger areas of the Christian
world. The challenge presented by the Muslims would help to
solidify the religious identity of eastern Christians even as it
gradually weakened the Eastern Empire.
Even in the Muslim
World, the Church survived (e.g. the modern Copts, Maronites, and
others) albeit at times with great difficulty.
Although there had long been frictions between
the Bishop of
Rome (i.e. the Western
Pope) and the other patriarchs, Rome's changing
allegiance from Constantinople to the Frankish
king Charlemagne set the Church on a course towards separation. The
political and theological divisions would grow until Rome
excommunicated the East in the 11th
century, ultimately leading to the division of the Church into
the Western
(Roman Catholic) and Eastern
(Eastern Orthodox) Churches. Some Eastern churches even broke with
Eastern Orthodoxy and entered into communion with Rome. The changes
brought on by the Renaissance eventually led to the Protestant
Reformation during which the Protestant Lutheran and the
Reformed followers of Calvin, Hus, Zwingli, Melancthon, Knox, and
others split from the Roman Catholic Church. At this time, a series
of non-theological disputes also led to the English
Reformation which led to the independence of the Anglican
Communion. Then during the Age of
Exploration and the Age of
Imperialism, Western Europe spread the Roman Catholic Church
and the Protestant and Reformed Churches around the world,
especially in the Americas. These
developments in turn have led to Christianity's being the largest
religion in the world today.
Origins
The Christian concept of a "Church" is used for the Greek (ecclesia, church, ekklesia), ref. [Strong's Concordance] 1577, Bauer's, Thayer's, and Moulton's and is introduced by Jesus of Nazareth in the New Testament. Of the 114 occurrences of the term in the New Testament, three are found in the Gospel of Matthew: "And I tell you that you are Peter, and on this rock I will build my ekklesia, and the gates of Hades will not overcome it" (Mt 16:18); and "If he refuses to listen to them, tell it to the ekklesia; and if he refuses to listen even to the ekklesia, let him be to you as the Gentile and the tax-collector" (Mt 18:17).The Greek term 'ekklesia', which literally means
a "gathering" or "selection" or "called out assembly", was a
governmental and political term used to denote a national
assembly.
This concept in Christian terms has its direct
antecedent in the Koine Greek translation of the Old Testament (see
also Septuagint), where the noun ekklesia has been employed 96
times to denote the congregation of the Children of Israel, which
Christians regard as a Type of the "Body of Christ", as they also
call the Christian Church of Jesus Christ.
Each church may recognize some or all other
Christian churches as legitimate. Mainstream denominations can be
far apart ecumenically, but generally do not require members to be
rebaptized when they switch from one denomination to another. They
share common ground in that they believe and follow Jesus Christ as
the savior, and seek to follow Jesus' teachings.
Related Concepts
Universal church
The term "catholic" is derived from the Greek adjective καθολικός pronounced katholikos, which means "general" or "universal".Church is taken by some to refer to a single,
universal community, although others contend that the doctrine of
the universal church was established until later. The doctrine of
the universal, visible church was made explicit in the Apostles'
Creed, while the less common Protestant
notion of the universal, invisible church was not stated explicitly
until the Reformation.
The universal church traditions generally accept that the Church
includes all who are baptized into her common faith, including the
doctrines of the trinity, forgiveness of sins through the
sacrificial action of Christ, and the resurrection of the body.
These teachings are expressed in liturgy with the celebration of
sacraments, visible
signs of grace. They
are passed down as the deposit of
faith.
Catholic and catholicism
This term appears in both the Nicene Creed and the Apostle's Creed, statements of faith adhered to by almost all modern denominations. When the word "catholic" or "universal" is applied to the Church, it is generally intended to indicate that the institution is the uniquely legitimate Christian church intended for all of humanity.In Christian
theology the term is often used to imply a calling to spread
the faith throughout the whole world and to all ages. It is also
thought of as implying that the Church is endowed with all the
means of salvation for
its members.
Saint Ignatius
of Antioch, the earliest known writer to use the phrase "the
Catholic church", excluded from it heterodox groups whose teaching
and practice conflicted with those of the bishops of the Roman-Catholic
church. In keeping with this idea, many churches and communions see
groups that it judges to be in a state of heresy or schism
with their church or communion as not part of the catholic Church.
E.g. the Roman
Catholic and Eastern
Orthodox Churches follow this doctrine.
Others have, since the Protestant
Reformation, used the word "catholic" to designate instead
adherence to the doctrines and essential practices of the
historical institutional Churches, in contrast to those propounded
by the Reformers. In this sense indicated in this paragraph,
"Catholic" tends to be written with an upper-case "C". The
Roman-Catholic church, the Eastern
Orthodox Church and the Oriental
Orthodox Churches all see themselves as fully "catholic" in all
the foregoing senses.
Some Anglicans see
their communion as a component part of the Catholic Church, albeit
not subject to the Holy See of
Rome, and maintain beliefs and practices akin to those of the
Roman-Catholic church. They are however not recognised by
Roman-Catholic or Orthodox tradition as being part of them.
Most other Protestant
denominations interpret "catholic", especially in its creedal
context, as referring to the concept of the eternal church of
Christ and the Elect, referenced in the Bible in phrases such
as "body of
Christ" and "great cloud of witnesses." Expressed in the
language of traditional Roman Catholicism this Protestant
interpretation of the words "one holy, catholic, and apostolic
church" identifies the "one holy, catholic, and apostolic church"
exclusively with the Church
Triumphant - i.e. the church that exists "in heaven" or in
eternity as opposed to the Church
Militant which is the communion of the faithful here on Earth.
They view this understanding of "catholic" as necessarily distinct
from any concrete expression in an institutional Church. In this
last sense, "catholic" tends to be written with a lower-case
"c".
Orthodoxy
The term orthodox is generally used to
distinguish the faith or beliefs of the "true Church" from other
doctrines which disagree, traditionally referred to as heresy.
This distinction can be seen as originating with
the biblical
proscriptions against false
prophets. "Orthodoxy" means both "true glory" and "correct
teaching" this theological term is explicitly used by Orthodox
Christians to refer to themselves as a shorthand for "the one,
holy, catholic, and apostolic, Orthodox and Orthoprax, Church of
Jesus Christ and His saints." In the same manner, the
Roman-Catholic church describes itself as orthodox, meaning having
possession of the whole faith. Of course, other Christian
denominations, who disbelieve the claims of the Orthodox Churches
refer to her thus as the "Eastern Orthodox" churches.
This concept of "orthodoxy" began to take on
particular significance during the reign of the Roman
Emperor Constantine
I, the first to actively promote Christianity. Constantine
convened the first Ecumenical
Council, the Council
of Nicea, which attempted to provide the first universal creed
of the Christian faith.
The major issue of this and other councils during
the fourth
century was the christological
debate between arianism
and trinitarianism.
Trinitarianism is the official doctrine of the Catholic church and
is strongly associated with the term "orthodoxy", although some
modern non-trinitarian churches dispute this usage. Churches that
subscribe to the Nicene
Creed, the first official trinitarian creed, are sometimes referred to
as "orthodox".
Apostolic succession
The doctrine of "apostolic
succession" asserts that the bishops of the true Church enjoy
the favor, or grace, of
God as a result of legitimate and unbroken sacramental succession
from Jesus'
apostles. Modern bishops, therefore, must be viewed as an
unbroken line of leadership from the original apostles. Note that
this doctrine is distinct from that of Papal
supremacy, which grants the Roman-Catholic
bishop of
Rome special powers in the Roman-Catholic church.
The Roman
Catholic Church, the Eastern
Orthodox Churches, the Oriental
Orthodox churches, the Anglican
Church Communion and others interpret the adjective "apostolic"
as referring not only to the Church's origin from Christ's Apostles
and their teachings, but also to the Church's structure around
bishops who have
succeeded the apostles by unbroken succession transmitted by
episcopal consecration (laying on of
hands), which is traceable to the Apostles themselves.
Spiritual authority
It is a widely held belief among Christians that the Christian church is guided by the Holy Spirit and given spiritual authority by Christ.According to Christian tradition the "authority"
of Jesus Christ to preach, to teach, and to do all the things that
He had done while on Earth came from God. Before Jesus Christ
ascended to Heaven He had given His apostles and disciples the
authority to preach (that may include teaching, exhorting,
rebuking, correcting) and to baptize. This "authority" was passed
on by the apostles to the disciples, and was to be passed from one
generation of disciples to the next until His second
coming. The passing on of this authority had been conducted
solely by the church. This passing on of authority was sometimes
called the anointing or
appointing of pastors or leaders of a church.
(Membership in the Christian church has
traditionally been defined by baptism. The church administers
Christianity's sacred acts: baptism, the Lord's supper, worship,
etc.)
The visible and the invisible church
Many believe that the Church, as described in the Bible, has a twofold character that can be described as the visible and invisible church.The Church invisible consists of all those from
every time and place who are vitally united to Christ through
regeneration and salvation and who will be
eternally united to Jesus Christ in eternal
life. The Church visible consists of all those who visibly join
themselves to a profession of faith and gathering together to know
and serve the Head of the Church, Jesus Christ.
The visible church exists globally in all who
identify themselves as Christians and locally in particular places
where believers gather for the worship
of God. The visible church may also refer to an association of
particular churches from multiple locations who unite themselves
under a common charter and set of governmental principles. The
church in the visible sense is often governed by office-bearers
carrying titles such as minister,
pastor, teacher, elder,
and deacon.
Some say that no reference to the church is ever
made in the Bible that is not referring to a local visible body,
such as the church in someone's house or the church as Ephesis.
They believe that the term is sometimes used in an institutional
sense in which the term refers to all of a certain type, meaning
all of the local visible churches.
Church government
Major forms of church government include hierarchical (Anglican, Eastern Orthodoxy, Roman Catholic), presbyterian (rule by elders), and independent (Baptist, charismatic, other forms of independency). Before the Protestant Reformation clergy were understood to gain their authority through apostolic succession, as still affirmed by the Anglican, Eastern Orthodox, and Roman Catholic churches.Metaphors
Christian scriptures use a wide range of metaphors to describe the Church. These include:- Family of God the Father (Bible verse |Ephesians|3:14-15|KJV,Bible verse 2|Corinthians|6:18|KJV)
- Brothers and sisters with each other in God's family (Bible verse |Matthew|12:49-50|KJV)
- Bride of Christ (Bible verse |Ephesians|5:31-32|KJV)
- Branches on a vine (Bible verse |John|15:5|KJV)
- Olive tree (Bible verse |Romans|11:17-24|KJV)
- Field of crops (Bible verse 1|Corinthians|3:6-9|KJV)
- Building (Bible verse 1|Corinthians|3:9|KJV)
- Harvest (Bible verse |Matthew|13:1-30|KJV,Bible verse |John|4:35|KJV)
- New temple and new priesthood with a new cornerstone (Bible verse 1|Peter|2:4-8|KJV)
- God's house (Bible verse |Hebrews|3:3-6|KJV)
- Pillar and foundation the truth (Bible verse 1|Timothy|3:15|KJV)
- Body of Christ (Bible verse 1|Corinthians|12:12-27|KJV)
- Temple of the Holy Spirit (Bible verse 2|Corinthians|6:16|KJV)
Divisions and controversies
Today the churches that consider themselves to be Christian are numerous with a variety of different doctrines and traditions. There are many controversies between the denominations which persist today.Existence of the notion of single Christian church
One significant controversy is simply the
definition of the notion Christian church or Catholic church. To
some degree this controversy is related to the Nicene
Creed, to which virtually all modern denominations subscribe
albeit in somewhat different forms, which specifically references a
catholic, or universal, church.
Both the Orthodox
Church and the Roman
Catholic Church have each traditionally regarded itself as the
one true and unique church of Christ, hence the names. Note that
the formulation of this principle by the Roman
Catholic Church in the document
Lumen Gentium of the Second
Vatican Council was purpously made ambiguous. This ambiguity
proved so contentious that in 2007 the Vatican Congregation for the
Doctrine of the Faith issued a clarification
document.[http://212.77.1.245/news_services/bulletin/news/20581.php?index=20581&lang=en#TESTO%20IN%20LINGUA%20INGLESE]
Many other Christian groups take the view that
all denominations are part of a symbolic and global Christian
church which is a body bound by a common faith if not a common
administration or tradition.
Note that in classical
times the term Catholic Church came to be most widely used in
reference to the official Roman Imperial church from which the
Catholic church, and all of its split offs descend directly or
indirectly. The term, however, dates back to the Apostles'
Creed which predates the official sanction of the Church by the
Empire.
Like the Roman Catholic Church, the Orthodox
Church and some others have always referred to themselves as the
Catholic church. Oriental
Orthodoxy shares this view, seeing the Churches of the Oriental
Orthodox communion as constituting the one true Church. In the
West the
term Catholic has come to be most commonly associated with the
Roman Catholic Church because of its size and influence in the West
(although in formal contexts most other churches still reject this
naming). These Churches believe that the term one in the Nicene Creed
describes and prescribes a visible institutional unity, not only
geographically, throughout the world, but also historically,
throughout history. They see unity as one of the four marks that
the Creed attributes to the genuine Church, and the essence of a
mark is that it be visible. A Church whose identity and belief
varied from country to country and from age to age would not be
"one".
In the New
Testament, the word "Church" or "assembly" - (ekklesia) in the
original language - normally refers to believers on earth, and they
conclude that the Creed's description "one" must be applicable to
the Church on earth and must not be reserved for some eschatological reality. The
only exception to the normal New Testament use of the word "" is
the mention of the " of the firstborn who are enrolled in heaven"
in Bible verse |Hebrews|12:23; and even there the Christians to
whom the letter is addressed are associated with that heavenly
Church ("you have come to..."). In line with this passage, the
ancient Churches mentioned see the saints too - that is, the holy
dead - as part of the one Church and not as ex-members, so that
Christians both in the present life and the afterlife form a single
Church.
Many Anglicans,
Lutherans,
Old
Catholics, and Independent
Catholics view unity as a mark of catholicity, but see the
institutional unity of the Catholic Church as manifested in the
shared Apostolic
Succession of their episcopacies, rather than a shared
episcopal hierarchy or rites.
Reformed Christians hold that every person
justified by faith in the Gospel committed to the Apostles is a
member of "One, Holy, Catholic, and Apostolic Church". From this
perspective, the real unity and holiness of the whole church
established through the Apostles is yet to be revealed; and
meanwhile, the extent and peace of the church on earth is
imperfectly realized in a visible way.
First church
The right to be considered the first or oldest
Christian Church is claimed by the Roman
Catholic Church, but also by the Orthodox
Churches and Anglican
Church. Christianity, of course, began with the birth of
Jesus
Christ in Roman
Judea and gradually spread westward into Asia
Minor, Egypt,
Illyria, Rome and
eventually the entire Empire.
The Roman
Catholic Church is linked to an unbroken succession of Bishops
of Rome, who trace their authority to Saint Peter,
the first Bishop of Rome.
The Orthodox Churches have argued that the
Scripture in no way designated Saint Peter as having unique
authority over the Church and that all the patriarchs of the Roman
Empire, including the bishop of Rome, as well as the local
Churches in Corinth, Thessalonica,
Ephesus and
many other places, even outside the Roman Empire, trace their roots
to the Twelve
Apostles.
Other debates
Other debates include the following:
- There are many opinions as to the ultimate fate of the souls of individuals who are not part of a particular institutional church, i.e. members of a particular church may or may not believe that the souls of those outside their church organisation can or will be saved.
- There have always been differing opinions as to the divinity of God, the Son and or his unity with God, the Father. Although historically the most significant debate in this arena was the arianism and trinitarianism debate in the Roman Empire, debates in this realm have occurred throughout Christian history.
- It has been debated whether or not the Christian Church is in fact a unified heavenly institution with the earthly institutions relegated to secondary status.
Criticisms
Throughout its history the Christian church, both
as a single abstract
entity and as concrete institutional groups has been criticized
both by outsiders and by its own members. (On criticisms of
Christianity in general, see Criticism
of Christianity.)
One criticism is that the Church does not accept
others and so does not follow the example of Jesus in accepting
children, women, gentiles, and adulterers, whom the religious
establishment and society of the time rejected. These critics often
pass over in silence his recommendations to "sin no more".
From early times some have seen the Church as
intolerant of outsiders and prone to fierce internal
disputes.
