The Complete Works Of Francisco Suárez - Commentaries on the Third Part of St. Thomas, Part IV, Volume XX - Francisco Suárez

This twentieth and final volume completes Suárez’s extensive commentary on the Third Part of the Summa Theologiae of Thomas Aquinas, bringing together his mature synthesis of Christology, sacramental theology, and ecclesiology.

The work focuses primarily on the sacramental economy of the Church, examining how the mysteries of Christ are communicated to the faithful through the sacraments. Suárez analyzes their institution, causal efficacy, and role in the application of redemption, emphasizing their dependence on the Passion of Christ as their ultimate source.

A further section is devoted to the Eucharist, treated as the central sacrament of Christian worship. Suárez discusses the real presence of Christ, transubstantiation, and the sacrificial dimension of the Mass, presenting the Eucharist as both sacrament and sacrifice in continuity with Christ’s saving work.

The volume also addresses final ecclesiological and eschatological themes, including the ongoing life of the Church as the mystical body of Christ and its consummation in eternal glory.

Throughout, Suárez maintains his characteristic precision and systematic method, integrating metaphysics, theology, and sacramental doctrine. As the concluding volume of the series, it presents a unified vision of Christ’s work as continuing in the life of the Church and culminating in the final union of the faithful with God.
