This work investigates the nature, function, and necessity of the seven gifts of the Holy Spirit in the life of the believer. Saint Thomas Aquinas, a 13th-century Dominican friar and Doctor of the Church, utilizes the Aristotelian-Thomistic framework to reconcile faith and reason. He argues that these gifts are supernatural habits that perfect the virtues, allowing the human soul to be moved directly by the Holy Spirit rather than solely by human reason.

Scholars and theologians regard this text as a foundational component of the Summa Theologiae, noting its high level of academic density and precise logical structure. It is frequently studied by students of medieval philosophy and systematic theology as a primary source for understanding the mechanics of grace.
