Definitely the right way to go. I was very troubled by the books and talks of both West and Popcak. The way they presented their theses, the tone they took, the analogies they used, and with Popcak, the heavy-handed way he pushed for “infallible loving”, completely ignoring situations where wives had valid reason to be hesitant in the bedroom, it all really upset me, so much that I threw away the books. My husband also was very put off by their presentation in their books and talks. While they may have not technically said anything that directly contradicts what the Church teaches, I had a sense of dread about adopting their attitude. Still, their books were so popular and I couldn’t find any other sources for a while. Now I know that there are many other good sources to form one’s conscience, but a fellow forum member here (shout out to LongingSoul) helped me to understand that** the intellect can only take a person so far, and then one must rely upon the Holy Spirit to illuminate the conscience**. Beyond the specific teachings of the Church is a tremendous opportunity to grow in discernment and holiness, and prayer and patience and the sacrament of Confession are the way to step into that region. The specific teachings of the Church cannot cover every single aspect of human life. Life is too varied and complex for that. So once we are sure we are already in obedience to the basic teachings, the only thing we can do next is ask Jesus to call us to Him, and then step out of that boat with our eyes on Him and then walk. That is the hope and the vision that I perceive in von Hildebrand’s and Grisez’s writings. That is why I have personally rejected the writings of Popcak and West (although I have still mentioned them to others at times as a primer in Catholic sexual ethics).
