Book excerpt: Professor Brian V. Johnstone, CSsR, has been quietly and unobtrusively contributing to the intellectual life of Catholicism, especially in the field of moral theology, for nearly four decades. Having published numerous theological articles on many topics, including biomedical ethics, peace and war, and fundamental moral theology, and directed many doctoral dissertations, it is no exaggeration to say that he has dedicated his entire life to teaching and writing theology. In honor of Johnstone's work, this felicitation volume covers a wide range of themes in the Christian moral life with original articles written by internationally recognized theologians. In the spirit of Johnstone's thought and work, each article challenges the reader to reflect upon the present while contemplating the future of moral theology.
