Jimmy Akin's article on the Christopher West Nightline interview is well worth reading:
Mr. West's approach to teaching TOB has a number of critics, including Dr. Scott Hahn and Dr. Alice von Hildebrand. Dr. von Hildebrand has written at least one very detailed commentary, of which I quote a small portion below, expressing the problems she sees with Mr. West's approach to TOB:
It is a joy to praise a great book or author; it is a grief and duty to criticize a bad one. But it is especially difficult to criticize someone who has many talents, whose work has positive sides, but which also suffers from certain faults, calling for correction. Such is the case with Christopher West, with his popular presentation of John Paul II’s “Theology of the Body.”
As gifted as he is—and as much as I appreciate all the good he has done for the Church—West’s work continues to fall short in many respects. He has sometimes misunderstood the authentic Catholic tradition; overlooked or disregarded essential aspects of it; and promoted a new form of religious “enthusiasm” which can best be described as wayward. Monsignor Ronald Knox, who critiqued this attitude so well in his book Enthusiasm, was a prophet, recognizing such outbursts as recurring phenomena in the history of the Church, characteristic of easily misguided movements for which we should always be on the watch.
Key to my concerns is West’s hyper-sexualized approach to the Theology of the Body. The French have a wonderful word to capture the veiling of one’s intimate feelings, out of a proper sense of shame—pudeur, a “holy bashfulness,” so to speak. Seized as he is by what he regards as his calling to evangelize a new generation with this theology in “modern” ways they can supposedly better understand, West practically ignores the importance of pudeur, and, by his imprudence, winds up undermining his own message.
well said... it is interesting to me that if you wonder if Mr. West 's TOB is over sexualized, some people here think that you must be a prude and think marital sex is a bad thing. The mere fact that it necessary to produce babies does not make it a bad thing - it is a necessary thing. But, let's not make married couples who aren't intimate all the time feel bad. That could be one unintended consequence of some of Mr. West's talks.
