Terminology
The
NT word for “church” is ekklēsia, which means
“gathering, assembly, congregation.” In classical Greek
the term was used almost exclusively for political gatherings. In
particular, in Athens the word signified the assembling of the
citizens for the purpose of conducting the affairs of the city.
Moreover, ekklēsia referred only to the actual meeting, not to
the citizens themselves. When the people were not assembled, they
were not considered to be the ekklēsia. The NT records three
instances of this secular usage of the term (Acts 19:32, 39, 41).
The
most important background for the Christian use of the term is the
LXX (Greek translation of the Hebrew Scriptures, dated c. 250
BC), which uses the word in a religious sense about one hundred
times, almost always as a translation of the Hebrew word qahal. While
qahal does not indicate a secular gathering (in contrast to ’edah,
the typical Hebrew word for Israel’s religious gathering,
translated by Greek synagōgē), it does denote Israel’s
sacred meetings. This is especially the case in Deuteronomy, where
qahal is linked with the covenant.
In
the NT, ekklēsia is used to refer to the community of God’s
people 109 times (out of 114 occurrences of the term). Although the
word occurs in only two Gospel passages (Matt. 16:18; 18:17), it is
of special importance in Acts (23 times) and the Pauline writings (46
times). It is found 20 times in Revelation and in isolated instances
in James and Hebrews. Three general conclusions can be drawn from
this usage. First, ekklēsia (in both the singular and the
plural) applies predominantly to a local assembly of those who
profess faith in and allegiance to Christ. Second, ekklēsia
designates the universal church (Acts 8:3; 9:31; 1 Cor. 12:28;
15:9; especially in the later Pauline letters: Eph. 1:22–23;
Col. 1:18). Third, the ekklēsia is God’s congregation
(1 Cor. 1:2; 2 Cor. 1:1).
The
Nature of the Church
The
nature of the church is too broad to be exhausted in the meaning of
one word. To capture its significance, the NT authors utilize a rich
array of metaphorical descriptions. Nevertheless, there are those
metaphors that seem to dominate the biblical pictures of the church,
five of which call for comment: the people of God, the kingdom of
God, the eschatological temple of God, the bride of Christ, and the
body of Christ.
The
people of God.
Essentially, the concept of the people of God can be summed up in the
covenantal phrase: “I will be their God, and they will be my
people” (see Exod. 6:6–7; 19:5; Lev. 26:9–14; Jer.
7:23; 30:22; 32:37–40; Ezek. 11:19–20; 36:22–28;
Acts 15:14; 2 Cor. 6:16; Heb. 8:10–12; Rev. 21:3). Thus,
the people of God are those in both the OT and the NT eras who
responded to God by faith and whose spiritual origin rests
exclusively in God’s grace.
To
speak of the one people of God transcending the eras of the OT and
the NT necessarily raises the question of the relationship between
the church and Israel. Modern interpreters prefer not to polarize the
matter into an either/or issue. Rather, they talk about the church
and Israel in terms of there being both continuity and discontinuity
between them.
Continuity
between the church and Israel. Two ideas establish the fact that the
church and Israel are portrayed in the Bible as being in a continuous
relationship. First, in the OT the church was present in Israel in
some sense. Acts 7:38 suggests this connection when, alluding to
Deut. 9:10, it speaks of the church (ekklēsia) in the
wilderness. The same idea is probably to be inferred from the
intimate association noted earlier existing between the words
ekklēsia and qahal, especially when the latter is qualified by
the phrase “of God.” Furthermore, if the church is viewed
in some NT passages as preexistent, then one finds therein the
prototype of the creation of Israel (see Exod. 25:40; Acts 7:44; Gal.
4:26; Heb. 12:22; Rev. 21:11; cf. Eph. 1:3–14).
Second,
Israel in some sense is present in the church in the NT. The many OT
names for Israel applied to the church in the NT establish that fact.
Some of those are “Israel” (Gal. 6:15–16; Eph.
2:12; Heb. 8:8–10; Rev. 2:14), “a chosen people”
(1 Pet. 2:9), “the circumcision” (Rom. 2:28–29;
Phil. 3:3; Col. 2:11), “Abraham’s seed” (Rom. 4:16;
Gal. 3:29), “the remnant” (Rom. 9:27; 11:5–7), “the
elect” (Rom. 11:28; Eph. 1:4), “the flock” (Acts
20:28; Heb. 13:20; 1 Pet. 5:2), and “priesthood”
(1 Pet. 2:9; Rev. 1:6; 5:10).
Discontinuity
between the church and Israel. The church, however, is not totally
identical with Israel; discontinuity also characterizes the
relationship. The church, according to the NT, is the eschatological
(end-time) Israel incorporated in Jesus Christ and, as such, is a
progression beyond historical Israel (1 Cor. 10:11; 2 Cor.
5:14–21). Indeed, significant discontinuity is introduced by
the fact that the church includes Gentiles as members of Israel,
without requiring them to convert to Judaism first. Gentiles enter as
Gentiles. However, a caveat must be issued at this point. Although
the church is a progression beyond Israel, it does not seem to be the
permanent replacement of Israel (see Rom. 9–11, esp. 11:25–27).
The
kingdom of God.
Many scholars have maintained that the life, death, and resurrection
of Jesus inaugurated the kingdom of God, producing the overlapping of
the two ages. The kingdom has already dawned but is not yet complete.
The first aspect pertains to Jesus’ first coming, and the
second aspect relates to his second coming. In other words, the age
to come has broken into this age, and now the two exist
simultaneously. This background is crucial in ascertaining the
relationship between the church and the kingdom of God, because the
church also exists in the tension that results from the overlapping
of the two ages. Accordingly, one may define the church as the
foreshadowing of the kingdom. Two ideas flow from this definition:
first, the church is related to the kingdom of God; second, the
church is not equal to the kingdom of God.
The
church and the kingdom of God are related. Not until after the
resurrection of Jesus does the NT speak with regularity about the
church. However, there are early signs of the church in the teaching
and ministry of Jesus, in both general and specific ways. In general,
Jesus anticipated the later official formation of the church in that
he gathered to himself the twelve disciples, who constituted the
beginnings of eschatological Israel—in effect, the remnant.
More specifically, Jesus explicitly referred to the church in two
passages: Matt. 16:18–19; 18:17. In the first passage Jesus
promised that he would build his church despite satanic opposition,
thus assuring the ultimate success of his mission. The notion of the
church overcoming the forces of evil coincides with the idea that the
kingdom of God will prevail over its enemies and bespeaks the
intimate association between the church and the kingdom. The second
passage relates to the future organization of the church, not unlike
the Jewish synagogue practices of Jesus’ day.
The
church and the kingdom of God are not identical. As intimately
related as the church and the kingdom of God are, the NT does not
equate the two, as is evident in the fact that the early Christians
preached the kingdom, not the church (Acts 8:12; 19:8; 20:25; 28:23,
31). The NT identifies the church as the people of the kingdom (e.g.,
Rev. 5:10), not the kingdom itself. Moreover, the church is the
instrument of the kingdom. This is especially clear from Matt.
16:18–19, where the preaching of Peter and the church become
the keys to opening up the kingdom of God to all who would enter.
The
eschatological temple of God.
Both the OT and Judaism anticipated the rebuilding of the temple in
the future kingdom of God (e.g., Ezek. 40–48; Hag. 2:1–9;
1 En. 90:29; 91:3; Jub. 1:17, 29). Jesus hinted that he was
going to build such a structure (Matt. 16:18; Mark 14:58; John
2:19–22). Pentecost witnessed to the beginning of the
fulfillment of that dream in that when the Spirit inhabited the
church, the eschatological temple was formed (Acts 2:16–36).
Other NT writers also perceived that the presence of the Spirit in
the Christian community constituted the new temple of God (1 Cor.
3:16–17; 2 Cor. 6:14–7:1; Eph. 2:19–22; see
also Gal. 4:21–31; 1 Pet. 2:4–10). However,
that the eschatological temple is not yet complete is evident in the
preceding passages, especially in their emphasis on the need for the
church to grow toward maturity in Christ, which will be fully
accomplished only at the parousia (second coming of Christ). In the
meantime, Christians, as priests of God, are to perform their
sacrificial service to the glory of God (Rom. 12:1–2; Heb.
13:15; 1 Pet. 2:4–10).
The
bride of Christ.
The image of marriage is applied to God and Israel in the OT (see
Isa. 54:5–6; 62:5; Hos. 2:7). Similar imagery is applied to
Christ and the church in the NT. Christ, the bridegroom, has
sacrificially and lovingly chosen the church to be his bride (Eph.
5:25–27). Her responsibility during the betrothal period is to
be faithful to him (2 Cor. 11:2; Eph. 5:24). At the parousia the
official wedding ceremony will take place, and with it the eternal
union of Christ and his wife will be actualized (Rev. 19:7–9;
21:1–2).
The
body of Christ.
The body of Christ as a metaphor for the church is unique to the
Pauline literature and constitutes one of the most significant
concepts therein (Rom. 12:4–5; 1 Cor. 12:12–27; Eph.
4:7–16; Col. 1:18). The primary purpose of the metaphor is to
demonstrate the interrelatedness of diversity and unity within the
church, especially with reference to spiritual gifts. The body of
Christ is the last Adam (1 Cor. 15:45), the new humanity of the
end time that has appeared in history. However, Paul’s usage of
the image, like the metaphor of the new temple, indicates that the
church, as the body of Christ, still has a long way to go
spiritually. It is not yet complete.
Sacraments
At
the heart of the expression of the church’s faith are the
sacraments of baptism and the Lord’s Supper. The former
symbolizes entrance into the church, while the latter provides
spiritual sustenance for the church.
Baptism.
Baptism symbolizes the sinner’s entrance into the church. Three
observations emerge from the biblical treatment of this sacrament.
First, the OT intimated baptism, especially in its association of
repentance of sin with ablutions (Num.19:18–22; Ps. 51:7; Ezek.
36:25; cf. John 3:5). Second, the baptism of John anticipated
Christian baptism. John administered a baptism of repentance in
expectation of the baptism of the Spirit and fire that the Messiah
would exercise (Matt. 3:11 // Luke 3:16). Those who accept Jesus
as Messiah experience the baptism of fire and judgment (which may be
an allusion to undergoing the great tribulation/messianic woes that
lead into the messianic kingdom). Third, the early church practiced
baptism in imitation of the Lord Jesus (Matt. 3:13–17 //
Mark 1:9–11 // Luke 3:21–22; see also John 1:32–34;
cf. Matt. 28:19; Acts 2:38; 8:16; Rom. 6:3–6; 1 Cor.
1:13–15; Gal. 3:27; Titus 3:5; 1 Pet. 3:21). These
passages demonstrate some further truths about baptism: baptism is
intimately related to faith in God; baptism identifies the person
with the death and resurrection of Jesus; baptism incorporates the
person into the community of believers.
Lord’s
Supper.
The other biblical sacrament is the Lord’s Supper. This rite
symbolizes Christ’s spiritual nourishment of his church as it
celebrates the sacred meal. Two basic points emerge from the biblical
data concerning the Lord’s Supper. First, it was instituted by
Christ (Matt. 26:26–29; Mark 14:22–25; Luke 22:15–20;
1 Cor. 11:23–25), probably as an adaptation of the
Passover meal. If that is the case, then, Jesus will have introduced
two changes into the Passover seder: he replaced the unleavened bread
with a reference to his body being given for us on the cross; he
replaced the cup of redemption with a reference to his shed blood on
the cross, the basis of the new covenant. Second, the early church
practiced the Lord’s Supper probably weekly, in conjunction
with the love feast (see 1 Cor. 11:18–22; cf. Jude 12). A
twofold meaning is attached to the Lord’s Supper by the NT
authors. First, it involves participation in Christ’s salvation
(Luke 22:19; 1 Cor. 11:24–25), and in two ways:
participating in the Lord’s Supper looks back to the death of
Jesus, in which the believer now shares; participating in the Lord’s
Supper looks forward to Christ’s return, the culmination point
of the believer’s salvation. Second, the Lord’s Supper
involves identification with the body of Christ, the community of
faith (1 Cor. 10:16–17; 11:27–33).
Worship
The
ultimate purpose of the church is to worship God through Christ and
in the power of the Holy Spirit (see, e.g., Rev. 4–5). The
early church first worshiped in the Jerusalem temple (Acts 2:46; 3:1;
5:42) as well as in the synagogue (Acts 22:19; cf. John 9:22; James
2:2). At the same time, and into the near future, believers met in
homes for worship (Acts 1:13; 2:46; 5:42; cf. Rom. 16:15; Col. 4:15;
Philem. 2; 2 John 10; 3 John 1, 6). Although many Jewish
Christians no doubt continued to worship God on the Sabbath, the
established time for the church’s worship came to be Sunday,
the day of Jesus’ resurrection (Acts 20:7; Rev. 1:10). The
early church most probably patterned its order of worship after the
synagogue service: praise in prayer (Acts 2:42, 47; 3:1; 1 Thess.
1:2; 5:17) and in song (1 Cor. 14:26; Phil. 2:6–11; Col.
1:15–20), the expounding of Scripture (Acts 2:42; 6:4; Col.
4:16; 1 Thess. 2:13; 1 Tim. 4:13), and almsgiving to the
needy (Acts 2:44–45; 1 Cor. 16:1–2; 2 Cor. 8–9;
James 2:15–17).
Service
and Organization
Five
observations emerge from the NT regarding the service and
organization of the early church. First, the ministry of the church
centers on its usage of spiritual gifts, which are given to believers
by God’s grace and for his glory as well as for the good of
others (Rom. 12:3; Eph. 4:7–16). Second, every believer
possesses a gift of the Spirit (1 Cor. 12:7; Eph. 4:7). Third,
it is through the diversity of the gifts that the body of Christ
matures and is unified (Rom. 12:4; 1 Cor. 12:12–31; Eph.
4:17–18). Fourth, although there was organized leadership in
the NT church, including elders (1 Tim. 3:1–7 [also called
“pastors” and “bishops”; see Acts 20:17, 28;
1 Pet. 5:1–4]) and deacons (1 Tim. 3:8–13),
there does not seem to have been a gap between the “clergy”
and the “laity” in the church of the first century;
rather, those with the gift of leadership are called to equip all the
saints for the work of the ministry (Eph. 4:7–16). Fifth,
spiritual gifts are to be exercised in love (1 Cor. 13).
