I’m light-years from an authority on Catholicism or blasphemy, but there looks to be a difference between that definition of blasphemy and this, no mention of “a holly person” unless the Pope is a “sacred entity”. :
1)A contemptuous or profane act, utterance, or writing concerning God or a sacred entity. b. The act of claiming for oneself the attributes and rights of God.If the Pope was really maligned, I might still agree if the Pope qualifies as "sacred", but he looked more like a feeble old man who was victimized rather than slandered. He was then the one who proclaimed that there was no miracle in the ovulating statue. I don’t think there was any intention to slander the Virgin Mary. A statue of her was just a vehicle for lampooning miracle groupies. I think the episode approached your definition of blasphemy, but stopped short.
2) An irreverent or impious act, attitude, or utterance in regard to something considered inviolable or sacrosanct.
The definition you cite is not substantially different from what I provided off-the-cuff. "Sacred entity" is a collective term for "sacred person or thing", and "holy" is synonymous with "sacred". Both the Virgin Mary and the Pope are holy persons to a Catholic, and the reference to the mentrual blood is obscene by any standard.
