An Expanded Trinitarian Glossary

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).

James Dobson in his book Marriage Under Fire illustrates the difference between husbands and wives.

The most eye-opening encounter between us occurred on our first Valentine’s Day together, six months after we were married. It was something of a disaster.
