However, in order to emphasize the incomparable greatness of the divine Liturgy and to benefit the faithful, whether as simple churchgoers or as communicants of the Cup of Life, I tried to refer to true events that have a direct or indirect relationship with the Mystery of the Divine Eucharist. These experiences were taken from the abundance of the Elders, the lives of the Saints, and from what I personally heard and saw during my forty-three years of priestly ministry from Elders and sanctified priests-ascetics, from blessed and humble priests-parish priests in the world, from monks of Mount Athos, and from simple but devout Christians.
