The Foursquare Church affirms Matthew 28:19 as the normative command of the risen Christ requiring baptism 'in the name of the Father, and of the Son, and of the Holy Spirit.' The Trinitarian formula is essential to valid Christian baptism and is consistently used in all Foursquare baptisms.

Baptism in the Foursquare Church is practiced as believer's baptism, administered to those who have made a conscious commitment to Christ. The Trinitarian formula connects the baptized believer to the threefold work of God in salvation: the Father's creative purpose, the Son's redemptive work, and the Holy Spirit's sanctifying presence and power.

Matthew 28:19 is also understood in Foursquare theology as the Great Commission, establishing the church's mandate to evangelize and make disciples of all nations. The Trinitarian formula affirms the church's partnership with the Triune God in this commission.
