It is not a matter of being different. All religious organizations are different. It is a matter of accurately understanding the teachings of Jesus as revealed in the New Testament. There are at least seven beliefs held by the Church of Christ which are different.
The church holds the Bible to be the only way that God now communicates His will to man. It holds the New Testament as the part in which Christians are instructed in matters of faith and practice. It holds the Bible to be verbally inspired, and the Bible's silence as an important element in understanding God's will for us.
The church holds that water baptism is a condition of the sinner's receiving God's forgiveness (Acts 2:38). One is not a Christian -- not a saved person until one has been baptized.
The church holds that the first century church observed the Lord's Supper on the first day of every week (Acts 20:7). Therefore, such is the practice of the Church of Christ today.
The church holds that singing in the first century church was a cappella style (without an instrument) (Colossians 3:16). Therefore, such is the practice of the Church of Christ today.
The church holds that each congregation was an independent body organized under the leadership of elders and deacons (Philippians 1:1). Therefore, the Church of Christ today is organized that way believing that such is the Lord's way.
The church holds that the Lord's church exists on earth today anywhere folks learn what first century Christians learned, believe what they believed, and practice what they practiced. It further believes such is exactly what God intended (Ephesians 3:20).
The church holds that all believers could be and should be united in the one body of Christ, and that this could be accomplished by the restoration of Christianity as it is revealed in the New Testament, and that such unity is the Lord's desire (John 17:21).
The Church of Christ is not trying to be different. It is different because of what it believes and practices that others do not believe and practice. And some of the differences are of such nature that they separate it spiritually, and therefore physically, from all others.
