“There once lived a most devout priest; (this incident was narrated to me by the blessed departed Gerontas (Spiritual Elder) Gabriel, who for a great period of time was the Abbott at the Holy Monastery of Dionysios on Mount Athos). Even though he barely knew how to read and write, he was a priest, a clergyman of strong faith, great virtue and of many spiritual struggles. He used to stand up-right for hours during the Proskomedia, despite the fact that the veins of his feet had been affected and were hemorrhaging. There were times when one could see the blood running down since he was standing up-right commemorating the names of numerous people. He was a man of sacrifice to his last breath; in fact, his soul departed just after the Divine Liturgy.
As he barely knew how to read and write, by some misundertsanding he did not place the portions on the Holy Diskos properly.
When we place the portion of the All-Holy (Panagia) Theotokos on top of the Holy Diskos, we say: “The queen stood at thy right hand…” The gerontas priest was under the impression that, since he said “at thy right hand”, the portion of the All-Holy (Panagia) Mother of God must be placed on the right side of the Lamb (as he was looking at the Holy Diskos); in other words, he was placing the portions backwards.
