This article is, personally, one of my favorites in the entire Summa of St. Thomas. It gives us the tools to quite lucidly explain the liturgical and patristic statements concerning the persons.
For example, we often state that the Son is "wisdom" (cf., 1 Cor. 1:24) or express the Spirit under terms like "sanctity" and "fire." Why is this the case since the attributes, as stated above, are really identical and predicated of each of the persons equally? This consideration was the fruitful source for much of the reflection that St. Augustine gave us in De Trinitate.
