==How to==

In general Orthodox practice, the right hand is used. The thumb, index, and middle finger are brought to a point. They are then placed on the forehead after that moved down to the sternum. Finally the hand is moved to the right shoulder and horizontally across to the left. [[Oriental Orthodox]] and Western Christians, however, go in reverse order on this last step, from left to right. As one moves through the Sign, one recites, at the forehead, "In the name of the Father"; at the sternum, "and of the Son"; and across the shoulders, "and of the Holy Spirit, Amen." There are variations that occur. For example, some may mark a very large cross, or a very small one. Some may say "and of the Holy ''Spirit''" across the shoulders. After moving the hand from one shoulder to the other, it may return to the sternum. It may be accompanied instead at times with the words of the [[Jesus Prayer]] in some form, or simply "[[Lord]] have mercy". The thumb, index and middle finger brought to a point symbolize the [[Trinity]], three persons sharing a single essence. The remaining two fingers are kept pressed close together and to the palm, representing the human and divine natures united together in [[Jesus Christ]].
