There you have the definition of perversion. That's been superceded by a new one--more limited--which encompassed homosexual activity only. Now even that use of the term is out-of-favor for the obvious reason: it's no longer correct to call a spade a spade.
You may think that the quotation above was from some Church-type; if not a Pope, then a ranking cleric, right?
That's Siggy Freud--naming the contraceptive mentality of Planned Parenthood (and others) as "perversion."
He's right, you know.
