The Christian Church (Disciples of Christ) operates on the motto 'No creed but Christ,' meaning that no formal doctrinal statement is imposed on members. However, Trinitarian faith is the working assumption of Disciples worship, theology, and ecumenical relationships. The denomination participates in the ecumenical movement and affirms the classic baptismal formula of Matthew 28:19.

The absence of a binding creed does not mean theological indifference; Disciples generally affirm Trinitarian Christianity but allow significant latitude in how members articulate their faith. This breadth is consistent with the founding vision of Stone and Campbell, who sought a Christianity united around Scripture and the confession of Jesus as Lord rather than around doctrinal systems.
