This book dedicates three essays each to three different theological problems regarding the Holy Spirit: In God and for Us (The "Filioque" and "Uncreated Grace"); Thomas's Understanding (Not His Commentators) of the Relation between nature and sanctifying grace; and our ability (and that of the angels at their creation) in fact to resist God' grace and thus be the first cause of sin. This later problem is developed in an "excursus" on the way God moves the free will, one that takes into consideration much recent work on this issue and situates the essays' position in relation to it. The book ends with a brief epilogue on the credibility of God, again giving Thomas's account of this. The principal aim throughout is to understand the doctrine of Thomas Aquinas. It places his views in relation to three audiences: chiefly to the orthodox regarding the first issue; to Catholics in relation to the second; and to Protestants in relation to the third. Thus, its second aim is to join "ecumenical debate" about these matters. The essays were mostly written to be delivered orally, to an informed audience of philosophers and theologians., but one that consisted of "generalists" and serious students of Thomas, as well as of "professional" philosophers and theologians. All three of the debated issues discussed have generated an enormous amount of disagreement and debate, not a little of it being quite "technical." Thus, each issue would easily require a long and significant book to be addressed as it deserves. The essays do not do this, but they do indicate what Torre holds is the "directive line" of Thomas's thought that deserves to be defended and developed in each case, and, in each case, this line is held to be markedly different than many have thought it to be.
