There are thousands of different churches in the world, but the Bible knows only one. Hear the inspired Apostle Paul: "There is one body, and one Spirit, even as ye are called in one hope of your calling; one Lord, one faith, one baptism, one God and Father of all who is above all, and through all, and in you all" (Ephesians 4:4-6).
Please notice that "there is one body." That one body is the church. Please note that God "gave Him (Christ) to be the head over all things to the church, which is His body, the fullness of Him that filleth all in all" (Ephesians 1:22,23). If the church is the body and there is one body, that means there is only one church which is approved by God. If there is but one church, then no man has any right to start another one. In fact, none of the churches founded by men have the approval of God. Our Lord Jesus Christ said: "Every plant, which my heavenly Father hath not planted, shall be rooted up" (Matthew 15:14).
While our Lord Jesus Christ lived on this earth, He responded to Peterís confession, "Thou art the Christ, the Son of the living God," by saying: "Upon this rock I will build my church" (Matthew 16:16-18). Please notice that Jesus used the singular. He did not say, "I will build my churches!" Nor did He promise to build many churches. He built only one! Because He is the Christ, the Son of the living God, He has the right to build the church. No one else can truthfully make the same claim. Therefore, no one else has the right to start a church or religious organization different from that one which Jesus built.
The church that Jesus built, the church of Christ, began on the first Pentecost following the resurrection and ascension of our Lord. We can read about its beginning in Acts, chapter 2.
Why not be content to become a member of Christís church? Follow the perfect pattern given for the church in the New Testament. Obey the same gospel which was preached on Pentecost day in the same way it was obeyed then and the same Lord will add you to the same church, the church of Christ!
You must believe in Jesus Christ, the Son of God (Mark
16:16; John 8:24). Repent of all your past sins (Acts 2:38; 17:30,31).
Confess your faith in Christ (Romans 10:9-10; Acts 8:37). Be buried with
Christ in baptism for the remission of your sins (Mark 16:16; Romans 6:4;
Acts 2:38). You will thereby be added by the Lord to His one true church
. .And the Lord added to the church daily such as should be saved"
