Father Hugo wrote this "defense of the evangelical ideal" in the mid-1940's to counter four separately published "attacks" against the doctrine that he and Father Onesimus Lacouture, S.J., taught in the silent retreats and that Father Hugo had taught in Applied Christianity. In precise theological arguments, Father Hugo shows that the doctrine is traditional and orthodox Catholicism, exposes his critics' errors, and makes clear that the real enemy he is meeting and counter-attacking in this book is the false doctrine of "pious naturalism."
