| Term | Definition |
| a koinonia of persons | When Migliore uses this expression, he means that God is a fellowship of love shared among three persons. He does not mean that God is just like us, and enjoys a friendship with others. |
| Perichoresis | mutual indwelling or "being in one another" |
| Eternity | This is not a communicable attribute. Mercy, love, and justice are communicable attributes. |
| Gregory the Great | He is not one of the Cappadocian Fathers. Gregory of Nazianzus, Gregory of Nyssa, and Basil of Ceasarea are Cappadocian Fathers. |
| Deus non est Genere | Thomas Aquinas (and Karl Barth) use this phrase to express that God is utterly unique. God is not a particular instance within a class. |
| via positiva | Theologians often employ a strategy of identifying divine attributes by choosing facets of existence that we find to be good and then "extending them out" to the nth degree. |
| persona | In his article on the Cappadocians, Allison reminds us that it is a mistake to imagine that this word (when translated into English) in the ancient world (especially when used to speak of God) meant personality rather, it meant a capacity for relationship. |
| individual self-consciousness | Proper trinitarian theology questions the modern understanding of person that grounds personal identity in this. |
| social nature of the triune God | Migliore warns that our understanding of this should not be a projection of our own ideals of community; to which he adds, we must not forget that God is God and we are creatures. |
| Karl Barth's retrieval of classical attributes (in dialectical pairs) | According to Migliore, this enables Barth to say that God is "free to be compassionate toward us, free to become vulnerable for our sake, without ceasing to be God." |
| Leonardo Boff | He believes that the Trinity lays a foundation for a society of brothers and sisters, of equals, in which dialogue and consensus are basic constituents of living together in the world and the church. |
| Marcina | Two of the great Cappadocian Fathers, Basil of Ceasarea and Gregory of Nyssa, were taught theology by her. |
| Divine Love | One of the key implications of speaking of this as the constitutive attribute of God, is the recognition that "God is the one who freely loves, and loves in freedom." |
