Your blessing is worse, because it is a sinful misfortune both for you in attempting to give something beyond your power, and for sandyeggo if she pretends to receive it.
Pope John Paul II scandalized some by giving a certain amount of reverance towards the Koran. If he sinned, which I don't necessarily grant because I believe his act was partially misunderstood, his sin affected no one but himself. And he certainly did nothing nearly as bad as what Pope St. Marcellinus (the 29th Roman Pontiff), who offered incense as a sacrfice to the gods in a moment of weakness during the persecutions to avoid martyrdom (he was later martyred anyway).
