“Again, the things we do, like acts of virtue, and the things nature does, are not contained in the same science, for the one pertains to moral, the other to natural science. But divine science deals with the things we do, treating virtues and precepts, and it also deals with things which are not our works, like angels and other creatures. It seems, then, that it is not one science.”

Review:
Having read two of St. Augustine’s key works (City of God and Confessions) the past two Lenten seasons, I felt that it was time to read from another saint. I wasn’t intimidated by the size after City of God, but as soon as I started reading, I realized that I’d picked up a heavy work of philosophy. Although I initially started to feel uncertain about my ability to understand it, I’m glad that I didn’t shy away from the challenge.
In this collection of writings, we get a mix of St. Thomas Aquinas’ early works through to his writings toward the end of his life (including his great Summa Theologiae). The topics range from Church doctrine, commentaries on ancient philosophers, and discussions of life and the angels, among other Biblical topics.
It took me some time to get used to the structure that he used, especially when it came to philosophical discussions and commentaries. As a modern reader, I had to keep reminding myself that these writings date back several centuries and are also translated, so things aren’t written as to the point as I’m used to. After my initial bout of frustration, I was able to grasp more without constantly wishing for an abbreviation.
Though it wasn’t intentional, I’m glad to have been acquainted with St. Augustine’s works before reading St. Thomas Aquinas, as the latter references the former frequently. Both of their works complement each other well, making it no wonder that both men have become Doctors of the Church.
I wish I could claim that I understood every word of this book. I had to take what I could and know there will be a time when I can revisit some of these concepts with fresh eyes. It was probably the most challenging book I’ve ever read, but it was a perfect discipline for Lent. By the time I reached the last couple of hundred pages, I was in a good routine. I need to remember how much I enjoy spiritual reading and remind myself that I don’t need to wait until Lent to come around again to pick up more works by the saints.
Likes & Dislikes:
What I liked:
- Reading his discussions on the angels was fascinating.
- Extremely well-balanced, offering both sides of an argument before commenting.
What I didn’t like:
- Again, as a modern reader, I found the writing style extremely repetitive, making me wish for simplified sentence structure.
Afterthoughts:
Having finished this and not giving up truly feels like an accomplishment.
