Christian Churches recognize two ordinances (not seven sacraments): baptism and the Lord's Supper. These are commanded by Christ and practiced by the apostolic church but are not sacraments in the Catholic sense of conveying grace ex opera operato (by the work done). Rather, they are visible signs of invisible grace and acts of obedience that express faith and covenant commitment.

Baptism is administered by immersion of believers only (credobaptism), never to infants. It is essential to salvation for those who hear the gospel, representing dying with Christ to sin and rising to new life. Following Acts 2:38, baptism is 'for remission of sins,' integrating it into the conversion process rather than treating it as merely commemorative. This distinguishes Christian Churches from most evangelical Protestants while maintaining that baptism's efficacy depends on faith and obedience, not on magical properties.

The Lord's Supper is celebrated weekly (in most congregations) as the primary gathered worship practice. It is understood as a memorial of Christ's death, where believers remember his sacrifice and renew covenant commitment. Real spiritual presence is affirmed, though transubstantiation is rejected. Instrumental music, permitting hymns and organ accompaniment, distinguishes this fellowship from the a cappella Churches of Christ.
