Calvary Chapel's expository method presents Matthew 28:19 as the risen Christ's mandate to baptize new believers in the name of the Trinity. Chuck Smith taught that this verse establishes the pattern: believers are to be baptized after becoming disciples of Christ. The singular 'name' emphasizes God's unity while the three persons (Father, Son, Spirit) are distinct.

In Calvary Chapel tradition, water baptism is a public declaration of faith following conversion, not conferring grace but witnessing to Christ's work. The Great Commission integrates baptism with making disciples and teaching them to obey all Christ's commands. Matthew 28:19 is thus foundational to church practice and missionary activity.
