The Eastern Orthodox Church affirms Matthew 28:19 as the scriptural foundation for Christian baptism administered in the Trinitarian name. Orthodox baptismal practice explicitly incorporates the Matthean formula, traditionally using triple immersion (one in the Father, Son, and Holy Spirit) as the sacramental form. The passage establishes both the command to baptize all believers and the proper invocation necessary for valid baptism. Patristic theology extensively commented on this passage as the basis for Trinitarian baptismal practice. In Orthodox theology, baptism is the sacrament of incorporation into the church and the foundation of Christian life, sanctified by the apostolic use of the Trinitarian formula.
