"St Elias died with the fingers of his right hand formed to make the Sign of the Cross in the position accepted even today in the Orthodox Church: the first three fingers together and the two outermost fingers folded onto the palm. During the struggle with the Old Ritualist Schism (seventeenth-nineteenth centuries) this information about the saint served as a powerful proof in favor of the present positioning of the fingers."
As so often is the case in the Orthodox Faith, the lives of the saints point the way to true orthopraxis (correct worship). To this day, Orthodox Christians cross themselves with this hand position. The three fingers joined in unity to represent the Three Persons of the Holy Trinity and the two fingers in the palm of the hand to represent the Dual Natures of Christ. We cross ourselves very often during the liturgies, and each time we invoke the central Truths of the Orthodox Faith, even down to our fingertips.
Saint Elias is commemorated on December 19th on the new calendar, and January 1st on the old calendar.
