Not just for April Fools Day either.
I think there are a few online hoaxes going around once again. We know the Fatimist hoax, the Sr. Lucia double, the incomplete secret, and now more absurdly, the newly found addition to the secret stating Church authority will be transferred to Fatima. (Here) Then there are all the Masonic conspiracy theories which tend to indict the Popes and Vatican II and the Novus Ordo. Many Catholics are deceived.
It reminds me of the Leo Taxil hoax, his fake conversion, as well as the Diana Vaughan hoax. I've written about it before. April Fools posts were unusual enough this year to suggest that some of the most faithful people online could maybe not be as faithful as we think. Pope Francis talks a lot about corruption and corrupt people. Leo Taxil was corrupt. He even deceived Leo XXIII, and of course, the Carmelites of Lisieux.
"About 1894 there appeared in France a series of self-styled revelations of the secrets of Freemasonry, published by a certain Dr. Bataille (Leon Taxil) and a woman called Diana Vaughan. These accounts gripped the imagination of the French public for a while. Later they were found to be false. The Servant of God took a certain interest in them at first, but long before there was any official denial of them she told us that they were not to be believed. Her only reason for rejecting them was the fact that Diana Vaughan once spoke against episcopal authority. 'That kind of thing cannot come from God, ' she said." - St. Therese By Those Who Knew Her
Keep that in mind when vetting the more preposterous things you read online. When Catholics speak against episcopal authority - especially and including the Pope - remember what St. Therese said about the Taxil hoax: 'That kind of thing cannot come from God.'
