The Bible uses a wide range of metaphors to describe the church. These include:
Family of God the Father (Ephesians 3:14-15,2 Corinthians 6:18)
Brothers and sisters with each other in God's family (Matthew 12:49-50)
Bride of Christ (Ephesians 5:31-32)
Branches on a vine (John 15:5)
Olive tree (Romans 11:17-24)
Field of crops (1 Corinthians 3:6-9)
Building (1 Corinthians 3:9)
Harvest (Matthew 13:1-30,John 4:35)
New temple and new priesthood with a new cornerstone (1 Peter 2:4-8)
God's house (Hebrews 3:3-6)
Pillar and foundation the truth (1 Timothy 3:15)
Body of Christ (1 Corinthians 12:12-27)
Prayers: Continuing the pattern of the Jerusalem church, the early church planters gave themselves to prayer as well as to preaching the gospel (see Acts 6:4). As in other cities, they had suffered labor pains in giving birth to the church at Thessalonica, and the infant church at Thessalonica was deeply ingrained in their hearts (see 2:13, 17; 3:5, 6).
As for the church of the Corinth read in your Bible 2Corinthians 1:2-7. A local church of God is a group of people who identify themselves with God and gather together to worship and serve Him. sanctified in Christ Jesus: The Corinthians holiness came from their position in Christ, not from their own goodness. The tense of the verb sanctified indicates that God had sanctified the Corinthians at a specific time in the past, producing a condition that they still enjoyed in the present. called to be saints: The work of Jesus Christ makes a believer holy forever in God's eyes.
Catholic Church & Apostolic Church = Christian Church
The phrase One, Holy, Catholic and Apostolic Church appears in the Nicene Creed and, in part, in the Apostles' Creed ("the holy catholic church", sanctam ecclesiam catholicam). The phrase sets out 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, the body of Christ (1 Cor 12:27), founded by the apostles and innately holy.
Conflicting boundaries and definitions
The Roman Catholic Church, comprising the one Western and 22 Eastern Rite particular Churches, teaches that the "one, holy, catholic and apostolic" Church subsists in it. The Eastern Orthodox Church, comprising about 16 mutually recognizing autocephalous hierarchical Churches, similarly teaches that it is the One, Holy, Catholic and Apostolic Church. Before the Great Schism of 1054, both sides saw themselves as belonging to the same One, Holy, Catholic and Apostolic Church. Oriental Orthodoxy shares this view, seeing the churches of the Oriental Orthodox communion as comprising the One, Holy, Catholic and Apostolic Church founded by Christ.
Both the Catholic Church and the Eastern Orthodox Church believe that the term "one" in the Nicene Creed describes and prescribes a visible institutional unity, not only throughout the world, but also throughout history. As they see it, unity is one of the four marks that the Creed attributes to the 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" in the original language - normally refers to believers on earth, and Catholics and Orthodox conclude that the Creed's description "one" must be applicable to the Church on earth. The only exception to the normal New Testament use of the word is the mention of the firstborn who are enrolled in heaven" in Hebrews 12:23; and even there the Christians to whom the letter is addressed are associated with that heavenly Church ("you have come to..."). Catholic and Orthodox teaching both include the saints - that is, the holy dead - in One Church and describe the Church as a community of Christians both in the present life and the afterlife, as well as historical entity.
Protestant and Evangelical Christians hold that the "One, Holy, Catholic, and Apostolic Church" refers to the "true" church of Christ and the Communion of Saints ( those who have been saved through Divine Grace). From this perspective, any earthly church is an imperfect man-made institution intended to represent the "true" church - the One, Holy, Catholic (Universality), and Apostolic Church that exists in eternity.
Anyone that repented and accepted Jesus Christ as their personal savior is born again. " Most assuredly, I say to you, unless one is born again, he can not see the kingdom of God." (John 3:3). Brothers and Sisters when you accepted Jesus Christ as your personal savior walk with Him, be like Him and hear the word of the Father with Him.
