St. Thomas Aquinas, often referred to as the ‘Angelic Doctor’, is one of the Catholic church’s greatest theologians. Thomas Aquinas Books are some of the most important to our Catholic faith. And he is known to be one of the best philosophers in history, especially during the middle ages. His contributions to natural law and western philosophy are as profound as Aristotle’s and Plato’s.
Just because Thomas wrote during the middle ages doesn’t mean he’s irrelevant to people today. The theology and philosophy he developed are as true today as they were back in his time. Despite what modern philosophy may say, human nature doesn’t change. And the lessons of Thomas Aquinas are timeless.
Saint Thomas wrote in the 1200s and was a member of the Dominicans. He spent most of his life teaching in universities around Europe. Back in those days, universities were places of debate and religious formation. Medieval universities produced great advances in philosophy, theology, law, politics, and science. These advancements would eventually become part of the scholastic movement.
There is so much more to be said about Saint Thomas. If you want to learn more about his life, we recommend the GK Chesterton biography below.

Thomas Aquinas Books
The books in this article provide an overview of Saint Thomas Aquinas’ thought. It is not an exhaustive list, and we encourage you to read more than what’s listed. Saint Thomas was a prolific writer. One of his influential works is the ‘Catena Aurea (Golden Chain)’, a commentary on the Gospels encompassing theology, philosophy, and textual commentary. This list will give you a good starting point either by reading Thomas Aquinas directly or by reading one of the books we recommend about Thomas Aquinas.
Summa Theologica/Summa Theologiae

The Summa Theologiae, sometimes called the Summa Theologic, is Saint Thomas’ most famous work. It’s so famous it’s often just referred to as The Summa. The Summa Theologiae is a compendium of the main theological teachings of the Catholic Church. It is an instructional guide for theology students, including seminarians and the laity. This contrasts the Summa Contra Gentiles, which is more apologetic.
It’s been taught in Catholic schools for centuries and is the gold standard for catholic theology.
In addition to the Summa, Thomas Aquinas’ reflections on the Hail Mary and the ten commandments are significant parts of his theological contributions.
The Summa is written in an interesting style with arguments in favor and against certain positions. It reads more like an encyclopedia than a history book or modern textbook. But if you are interested in learning more about Catholic theology and natural theology there is no better book.

Saint Thomas is best known for his work on natural law. But he also wrote many insightful commentaries. He wrote commentaries on each of the Gospels–Mathew, Mark, Luke, and John. Each provides excellent lessons for anyone reading the Gospels. Saint Thomas is a model teacher; you can learn much from this spiritual master.
The Summa Theologiae gets all the attention for its exposition on natural reason. But the truth is that Saint Thomas’ Gospel commentaries can often provide more insight to the average person because they’re more accessible. Many people think that Saint Thomas only wrote dense books on metaphysics, but they forget that he had a mystical experience. As a philosopher Thomas Aquinas is unmatched, but he’s underappreciated as a mystic and commenter on the faith.
On Law, Morality, & Politics

Thomas Aquinas, like his favorite philosopher Aristotle, wrote about everything. Not only did he have a profound impact on church history, but he also advanced natural law ideas about politics and morality. His book On Law, Morality, & Politics furthers philosophical ideas started by Plato and Aristotle making them Catholic and part of the Western world.
