It must be true: I read it on the internet.
One of the more infamous bits of anti-Catholic bigotry circulating over the last century or two is the so-called "Jesuit Oath," sometimes in the form of the "Knights of Columbus Oath." As a third degree Knight, I can testify that we take no such oath. Needless this say, it has found its way onto the internet and even You Tube. Read about how this vile lie got itself into the Congressional Record and the Library of Congress in The Jesuit Oath Debunked.
