About This Volume On the Nature of God and the Trinity includes two of Gerhard's commonplaces: On the Nature of God and On the Most Holy Mystery of the All Hallowed and Ineffable Trinity. On the Nature of God explores the etymology of the name of God and attends to His various attributes. Among others, Gerhard defines and defends God's simplicity, eternality, immutability, infinity, omnipotence, goodness, mercy, justice, omniscience, freedom, perfection, and majesty. On the Most Holy Mystery of the All Hallowed and Ineffable Trinity presents and defends six propositions concerning the Trinity: that the Trinity must be known and believed to be saved, that the mystery should be taught and preserved, that the Trinity can and ought to be proved from the scriptures, that both the Old and the New testaments witness to the Trinity, that reason is insufficient to prove the Trinity, and that the Trinity ought not be overruled or ridiculed by force of reason.
