Crossed fingers - wikipedia Crossed fingers See also : Cross-fingering Crossed fingers To cross one 's fingers is a hand gesture commonly used to wish for luck. Occasionally it is interpreted as an attempt to implore God for protection. The gesture is referred to by the common expressions `` cross your fingers '', `` keep your fingers crossed '', or just `` fingers crossed ''. Some people, mostly children, also use the gesture to excuse their telling of a white lie. By extension, a similar belief is that crossing one 's fingers invalidates a promise being made.

The origin of the gesture traces back to the biblical Kingdom of Israel. Courts of Mosaic law would often render verdicts with the phrase `` May God have mercy upon your soul '' in order to reaffirm God 's supreme authority over the law. Most judges felt that while they could pass a sentence of death upon a person, they personally did not have the authority to destroy souls and that only God had the authority to do that. As a result, some judges would cross their fingers whenever they said the phrase as a result of concern for the criminal 's soul as they said it as a prayer. Common usage of the gesture traces back to the early centuries of the Catholic Church. Common use of crossed fingers is found in the Christians who would cross their fingers in order to invoke the power associated with Christ 's cross for protection, when faced with evil. Moreover, Christians, when persecuted by the Romans, used the symbol of crossed fingers in order to recognize one another and assemble for Holy Mass. `` When they were persecuted in Rome, Christians would secretly come together with the sign of the fish, and they would hold up their crossed fingers, as a Sign of the crossed emblem that had once been on the vestments of the army of Barabbas. It became a custom everywhere, for Christians when meeting, to make the sign of a cross by crossing their fingers. '' In 16th century England, people continued to cross fingers or make the sign of the cross in order to ward off evil, as well as when people coughed or sneezed. This superstition thus became popular among many early European Christian cultures. In some places, a comrade or well - wisher placed his index finger over the index finger of the person making the wish, the two fingers forming a cross. The one person makes the wish, the other empathizes and supports. Over centuries, the custom was simplified, so that a person could wish on his own, by crossing his index and middle fingers to form an X. But traces remain -- two people hooking index fingers as a sign of greeting or agreement is still common in some circles today. Charles Panati believes that the act of crossing one 's fingers as a sign of luck or making a wish traces back to pre-Christian times, speculating that the cross was a symbol of unity and benign spirits dwelt at the intersection point. A wish made on a cross was a way of `` anchoring '' the wish at the intersection of the cross until the wish was fulfilled. Anecdotal use The 1787 A Provincial Glossary, with a Collection of Local Proverbs, and Popular Superstitions by Francis Grose records the recommendation to keep one 's fingers crossed until one sees a dog to avert the bad luck attracted by walking under a ladder.
