There are some books you read. These books, you read, and read again, and read again, and probably never stop repeating this process:
At some point I will try to discuss each of these, their value, and suggestions on “how to use” them. They are not simply books; they are resources for a life of growth.
The first two are simply a primer on thinking straight. The next three get you focused on the Word of God, Jesus Christ, who is Truth Himself. To know the Truth is to know Christ, and vice versa. After that, three books go deeper into some specific truths of reality, informed by faith, but not entirely derived from it. The second to last book, Reality, is just that: a synthesis of reality, informed by both faith and reason (in this it derives much from Thomas’ five volume Summa above, but with a much different presentation). The last selection needs no explanation to those who are drawn by grace to the highest in truth.
For now, regarding the Summa Theologica in Five Volumes as listed above, see my earlier post on the Concise Translation of the Summa.
