The Complete Works Of Francisco Suárez - On the One and Triune God, Volume I - Francisco Suárez

This first volume presents Suárez’s systematic treatment of the doctrine of God, focusing on divine unity and the mystery of the Trinity within the scholastic tradition. Writing in the context of mature post-medieval scholasticism, Suárez develops a highly structured metaphysical account of God as the absolutely simple, infinite, and necessary being.

The work begins with natural theology, examining what human reason can know about God’s existence and attributes. It then proceeds to the doctrine of divine simplicity, perfection, and infinity, carefully analyzing how all divine attributes are identical in the one essence without division or composition.

A major portion of the volume is devoted to Trinitarian theology. Suárez explains the distinctions of persons in God through relations of origin—paternity, filiation, and spiration—while preserving the absolute unity of the divine essence. He offers detailed metaphysical reasoning to clarify how real personal distinctions exist without introducing multiplicity in the Godhead.

Throughout, Suárez employs a rigorous scholastic method characterized by conceptual precision and careful argumentation. The volume stands as a comprehensive exposition of classical Catholic doctrine on the one God and the Trinity, synthesizing earlier scholastic developments into a unified metaphysical framework.
