Here we will examine, that if indeed, there is only one church.
The first notion to dispel is, that scripture identifies there being only one church in existence.
There was a church ( a congregation) in the wilderness before Christ came that worshiped the Lord...........[Acts 7:38 KJV] 38 This is he, that was in the church in the wilderness with the angel which spake to him in the mount Sina, and [with] our fathers: who received the lively oracles to give unto us:
[Exodus 34:14 KJV] 14 For thou shalt worship no other god: for the LORD, whose name [is] Jealous, [is] a jealous God:
If this church is acknowledged, is it unimaginable that there could be others formed during other dispensations?
Jesus established his church...........[Matthew 16:18 KJV] 18 And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it.............Lord Jesus chose twelve disciples to be apostles............[Luke 6:13 KJV] 13 And when it was day, he called [unto him] his disciples: and of them he chose twelve, whom also he named apostles;
[Acts 2:14 KJV] 14 But Peter, standing up with the eleven, lifted up his voice, and said unto them, Ye men of Judaea, and all [ye] that dwell at Jerusalem, be this known unto you, and hearken to my words:
[Acts 2:41 KJV] 41 Then they that gladly received his word were baptized: and the same day there were added [unto them] about three thousand souls...........those that believed Peter were baptized, and were ADDED to them..............[Acts 2:47 KJV] 47 Praising God, and having favour with all the people. And the Lord added to the church daily such as should be saved..........The Lord ADDED to them, the existing church, the church Jesus built during his time on earth. A new church was NOT formed at Pentecost. This church continued thru, and beyond the conversion of Paul.
This existing church, built by Jesus, was the church that Paul persecuted before his conversion. This was the church of God, the church at Jerusalem, the little flock........[Acts 8:1 KJV] 1 And Saul was consenting unto his death. And at that time there was a great persecution against the church which was at Jerusalem; and they were all scattered abroad throughout the regions of Judaea and Samaria, except the apostles.
[1Corinthians 15:9 KJV] 9 For I am the least of the apostles, that am not meet to be called an apostle, because I persecuted the church of God.
This church was never called the body of Christ.
Paul was saved and chosen by the Lord Jesus to be an apostle to the Gentiles...........[Romans 11:13 KJV] 13 For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office:
Peter and Paul had separate apostleship..............[Galatians 2:8 KJV] 8 (For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles:)..........Peter was apostle to the Jews, and Paul to the Gentiles. Peter and Paul were not apostles over the same church. Their was no animosity between Peter and Paul. Paul could never have been selected as an apostle to the church in Jerusalem because he didn't meet the requirements. To be an apostle with Peter and the twelve, he would have to have been with the other apostles during the entire time Jesus was on earth, beginning from the baptism of John until the ascension of Christ..........[Acts 1:21-22 KJV] 21 Wherefore of these men which have companied with us all the time that the Lord Jesus went in and out among us, 22 Beginning from the baptism of John, unto that same day that he was taken up from us, must one be ordained to be a witness with us of his resurrection.
Paul received revelations from the risen Christ Jesus............[Ephesians 3:3-4 KJV] 3 How that by revelation he made known unto me the mystery; (as I wrote afore in few words, 4 Whereby, when ye read, ye may understand my knowledge in the mystery of Christ)...............Among these revelations, Paul received knowledge of the church Jesus formed for this dispensation of grace. Christ revealed that the church in this dispensation was the body of Christ, and it's members are members of his body. Christ revealed offices and functions to be set in place in the body of Christ.............[1Corinthians 12:27-28 KJV] 27 Now ye are the body of Christ, and members in particular. 28 And God hath set some in the church, first apostles, secondarily prophets, thirdly teachers, after that miracles, then gifts of healings, helps, governments, diversities of tongues.........................Revealed was Christ as the head of the body............. [Colossians 1:18 KJV] 18 And he is the head of the body, the church: who is the beginning, the firstborn from the dead; that in all [things] he might have the preeminence..............Nowhere was the church in Jerusalem, overseen by Peter and the apostles, referred to as being the body of Christ. Nowhere was it said that Jew and Gentile were one body in the church overseen by Peter. Only in the body of Christ was Jew and Gentile revealed to be reconciled in one body............... [Ephesians 2:16 KJV] 16 And that he might reconcile both unto God in one body by the cross, having slain the enmity thereby:
Paul said that the body of Christ would sit in heavenly places..........[Ephesians 1:3 KJV] 3 Blessed [be] the God and Father of our Lord Jesus Christ, who hath blessed us with all spiritual blessings in heavenly [places] in Christ:
[Ephesians 2:6 KJV] 6 And hath raised [us] up together, and made [us] sit together in heavenly [places] in Christ Jesus:..........Peter never spoke of himself, or his church, as sitting in heavenly places. Paul said that by the church, the body of Christ, the principalities and powers in heavenly places would know by the church, the body of Christ, the manifold wisdom of God..............[Ephesians 3:10 KJV] 10 To the intent that now unto the principalities and powers in heavenly [places] might be known by the church the manifold wisdom of God,..............this was not made known by Peter's church.
What was made known by the preaching of the gospel of the kingdom by Peter and the apostles was that their believing members, would become a holy nation and a kingdom of priests; they would reign with Christ in his earthly kingdom.................[Exodus 19:6 KJV] 6 And ye shall be unto me a kingdom of priests, and an holy nation. These [are] the words which thou shalt speak unto the children of Israel.
[Revelation 20:6 KJV] 6 Blessed and holy [is] he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years..............Only Israel was told they would be a kingdom of priests. Nowhere does Paul say the members of the body of Christ are, or will be made priests; this differentiates Peter's church from the body of Christ. Only Peter's church could have the expectation of being priests in the kingdom on earth.
It has been determined that Paul was not qualified to be an apostle along with the twelve apostles in Peter's church according to Acts 1:21-22, as discussed above, yet PAUL IS AN APOSTLE............[Romans 1:1 KJV] 1 Paul, a servant of Jesus Christ, called [to be] an apostle, separated unto the gospel of God,...............One of the qualifications in Acts 1 :21-22 was "must one be ordained to be a witness with us of his resurrection.", Paul did see the risen Christ, and did meet this qualification to be an apostle.......................[1Co 9:1 KJV] 1 Am I not an apostle? am I not free? have I not seen Jesus Christ our Lord? are not ye my work in the Lord?..............Paul however, not only could he not be a replacement apostle for Judas, but he also could not be set equally beside Peter and the others as an apostle if there was just one church at the time.
For Paul to be an apostle, he would have had to be an apostle for a DIFFERENT CHURCH. Paul is an apostle to the church, the body of Christ, which means, the body of Christ IS A DIFFERENT CHURCH, ANOTHER CHURCH.
The only conclusion that can be reached is that there are TWO CHURCHES. There is Peter's church and there is the body of Christ. Peter's church was still in operation during Paul's ministry to the body of Christ. The body of Christ is not the same church as Peter's church. Neither is it Peter's church fully manifested in knowledge thru the completed progressive revelation given to the apostle Paul. These two churches have different apostles. These two churches have different destinies; Peter's church is destined to reign with Christ on earth; the body of Christ is destined to dwell in heavenly places. Two churches with different purposes; Peter's church will reconcile the earth and be a blessing to the nations in the kingdom on earth; the body of Christ will reconcile the heavens and make know the wisdom of God. Scripture presents two distinct churches in Christ Jesus.
Footnote: In describing the church at Jerusalem I used the term "Peter's church" only out of convenience It was not Peter's church, It was The Lord Jesus Christ's church.
