Elder Paisos was asked, “Geronta, why do temptations often occur on feast days?”
Don’t you know? On feast days, Christ, the Panagia, and the Saints are joyful. They treat people, giving blessings and spiritual gifts. If parents give gifts when their children celebrate their namedays and kings release prisoners when a prince is born, why shouldn’t the Saints care for us on special occasions, too? Certainly the joy they give greatly endures and our souls are greatly helped. Knowing this the devil creates temptations in order to deprive people of the Divine gifts: they neither rejoice nor benefit from the feast. Sometimes you even see when a family is preparing to commune on a feast day, that the devil will send them a temptation to fight and then not only do they not commune, but they don’t even go to church! That’s how the little demon does it, so as to be deprived of all Divine help.
The same thing can be seen in our own monastic life. Many times the little demon—tempter that he is, because he knows from experience that we will be spiritually helped on some feast—will, beginning on the eve of the feast, create an atmosphere of temptation. For example, he might get us to quarrel with another brother, and then afterwards torment us in order to overpower us both spiritually and bodily. In this way he doesn’t allow us to benefit from the feast, with its joyous atmosphere of doxology. But the Good God helps us when He sees that we had not given occasion, but that this happened only by the envy of the evil one. And God helps us even more when we humbly reproach ourselves, blaming neither our brother nor even the devil, who hates everything good. For his work is this: to create scandals and spread evil—while man, as the image of God, should spread peace and goodness.
