Aristotle's thinking has had a profound influence on Catholic theology. You may have heard of Thomas Aquinas. If you haven't, he was a significant Catholic theologian, and Aristotle figured prominently in his thought.

You seem to find nothing wrong with unmarried men making policy on marriage. I suppose that you would want admiralty law written only by people who lived inland and had never gone to sea, or the laws governing the use of automobiles written only by non-drivers. In both cases, with no input from the experienced.

Humanae Vitae is a brilliant example. Written by a celibate -- indeed, the man was very likely a virgin -- and who had never in his career had what the Anglicans call a "cure of souls". He was a man who didn't have a clue about the place of sex in marriage -- clearly the sort of man you believe should be setting policy on the subject, since you make it quite clear that you prefer the inexperienced to deal with matters rather than those who know the subject.
