Brethren in Christ interpret Matthew 28:19 as the baptismal formula reflecting Trinitarian theology. The singular 'name' emphasizes the unity of the Godhead (Father, Son, Holy Spirit) while affirming distinct persons. BIC practices believer's baptism—baptism of confessing individuals who have made conscious profession of faith in Christ, not infant baptism.

For BIC, baptism is the outward sign of inward faith and commitment to follow Christ. The passage commissions disciples to make disciples and baptize them, emphasizing the connection between faith, discipleship, and the sacrament. Matthew 28:19 is also central to the Great Commission and the missionary calling of the church.
