Sign of the cross

The Sign of the Cross is a ritual performed mainly within Roman Catholicism and Eastern Orthodoxy, as well as Eastern-Rite Catholicism, Anglicanism, and Lutheranism. For the members of the Faith, it symbolizes by manifestly marking directly on one's own body or in the air, the four points of the Cross on Calvary. It also represents loving God with all one's heart, soul, mind and strength. There are two particular arrangements one is most likely to observe. One is followed by many of the Eastern Churches, the other by the Western (Latin) Rite of Roman Catholicism and the Oriental Orthodox.

Double-cross

The English-language expression "double-cross" has led to some fake etymology: the fact that the sign is made in one direction in the Western rite, and the other in the Eastern rites, leads to its sometimes informal use for two people to identify themselves and others as being from the West or East. There was a period in the Middle Ages when some Venetian merchants and others would cross themselves in the Western fashion when meeting with Westerners, and in the Eastern fashion when meeting with Easterners. This duplicity supposedly led to the coining of the phrase "double crosser" to mean someone who professes to be aligned with one party, but in reality is aligned with an opposing party or with no party.

The actual origin of the expression "double-cross" which dates in English from only 1834, has to do with "fixing" a horse-race in a pre-arranged swindle that is only very loosely connected with the sign of the cross.
