 I don't even know where this came from, and the truth is people don't know sort of where this practice originated. Some people think that it originated in Christian churches, and the idea was that Christians would make this sign of the cross and hide it when they were telling a lie or saying something that was not true as a way of sort of protecting themselves from the repercussions of having broken one of the Ten Commandments. So it's like if you're going to do something bad, so long as you make the sign of the cross while you do it, you're covered, this sort of idea, this superstitious idea.
