More testimony from Pope Pius XII in the 1950’s:
Consequently, unless we are willing that the responsibility of procreating life should be left to the arbitrary decision of men, we must accept that there are certain limits, beyond which it is wrong to go, to the power of (a person) over (her or) his own body and its natural functions—limits, let it be said, which no one, whether as a private individual or as a public authority, can lawfully exceed. These limits are expressly imposed because of the reverence due to the whole human organism and its natural functions, in the light of the principles We stated earlier, and in accordance with a correct understanding of the “principle of totality” enunciated by Our predecessor Pope Pius XII. (See Pius XII, Address to Association of Urology: AAS 45 (1953), 674-675; to leaders and members of Italian Association of Cornea Donors and Italian Association for the Blind: AAS 48 (1956), 461-462 [TPS III, 200-201].)
Reverence for the person: a very high ideal. Preaching that ideal is very challenging when the preacher may be perceived as less respectful of other areas of human expression. A Church with credibility might well be more persuasive if their message in “totality” were perceived more strongly.
That said, that a person or institution lacking credibility in one area can certainly be correct in another–it doesn’t sink a whole set of virtues that human beings and institutions are not perfect, either in expression or, just as importantly, how they communicate desired values.
Thoughts on that?
