Archbishop Lefebvre's last book. Describes a sanctity, simple yet profound, based on the writings of Saint Thomas Aquinas. "Souls find in the Summa not only the light of the faith, but also the source of sanctity."

Originally for priests and seminarians, it is now a popular favorite. In satisfying the intellect rather than the emotions, we're encouraged to make "a total and unreserved offering of ourselves to God by our Lord Jesus Christ Crucified."
