The Coptic Orthodox Church affirms Matthew 28:19 as the biblical foundation for Christian baptism administered in the name of the Holy Trinity. Coptic baptismal practice explicitly follows this apostolic formula, invoking the names of the Father, Son, and Holy Spirit. Baptism in Coptic theology is the sacrament of entry into the church and incorporation into Christ's body. The passage establishes both the universality of Christian salvation (all nations) and the Trinitarian invocation necessary for valid baptism. Coptic baptismal theology understands baptism as a mystery involving grace, chrismation, and the gift of the Holy Spirit.
