At baptisms, we repeat the words of Christ in the Great Commission “in the name of the Father, Son, and Holy Spirit” without realizing that we are referring to the stragglingly in-depth doctrine of the Trinity. Jesus in the taught both the oneness of God’s essence and the threeness of the Persons in the Trinity in the baptismal formula: “Baptize in the name of the Father, Son, and Holy Spirit” (Mt 28:19). The one deity of the Trinity is seen in the singular “name” because God is one in substance or essence. But then Jesus followed up saying baptize in the name of the Father, Son, and Holy Spirit” or the three persons of the Trinity.
