Summa Theologica, Part III (Tertia Pars) From the Complete American Edition

The third part of this towering medieval theological treatise turns its careful mind to the mystery of the Incarnation. Presented in a clean, modern translation, it guides listeners through a systematic series of questions that examine why the divine Word assumed human flesh, how the two natures were united, and what that means for Christ’s knowledge and will. The editor’s notes make the structure easy to follow, while the prose retains the logical rigor of its original author.

Each article treats a single point—such as the fitness of the Incarnation, the grace of Christ as man and head of the Church, or the role of the Blessed Virgin—by posing a precise question and then exploring it step by step. Listeners will hear thoughtful arguments about the unity of Christ’s being, the limits of his human nature, and the theological implications for worship and doctrine. The result is an inviting invitation to contemplate foundational Christian beliefs through reasoned, articulate discussion.
