Many people who are in the Church of Christ said that members of the Church of Christ are Christians, but not others as they pretend to be. In other words a person who is not the member of Church of Christ is not the real Christians. The members of the Church of Christ are said to be Christians, only on the basis of self-righteousness. The Bible plainly teaches that "salvation is in Christ" (II Tim 2:10, Acts 4:12) and that "To be in Christ is to be in the body of Christ", which is the Church of Christ (Col 1:18, Eph 1:22-23, Acts 10:18, Heb 9:22, Rom 5:8-9). The Bible says "one God, one Lord, one Sprit, one hope, one faith, one baptism and one body" (Eph 4:4-6). In fact God is one and we are one body (Church of Christ for which Jesus Christ died). The Bible authorizes only one true Church of Christ which is his body, the Church which was purchased by the blood of Christ, as Acts 20:28 "Church of God, which He hath purchased with his own blood". God planed this Church in eternity (Please refer the following verses, Eph 2:13-18, 3:10-11, 1:22-23, 4:4). The Old Testament prophets proclaimed of that one Church (Isa 2:1-4).Christ builds it and Christ is the founder.
