SDA Belief No.13 - Unity in the Body of Christ:
The church is one body with many members, called from every nation, kindred, tongue, and people.

In Christ we are a new creation; distinctions of race, culture, learning, and nationality, and differences between high and low, rich and poor, male and female, must not be divisive among us.

We are all equal in Christ, who by one Spirit has bonded us into one fellowship with Him and with one another; we are to serve and be served without partiality or reservation.

Through the revelation of Jesus Christ in the Scriptures we share the same faith and hope, and reach out in one witness to all. This unity has its source in the oneness of the triune God, who has adopted us as His children.
