Christ is risen.
An interesting thread. I did, actually, the first time I saw this practice, think that it had been imported from the satanic "Charismatic" movement. But it does, as we know, have an ancient history, and a modern history which is not limited to the Oriental churches. In Munich, in the early 20th century, the orans was common among the people attending Roman Catholic Mass.
It's similar to the old Western Rite practice of praying "in the cross," that is, with one's arms stretched out wide like Christ crucified. Which is done by the priest at the old Roman rite Mass, but not by the people, who, however, do use this posture in their private prayers. Or used to.
