“After the change of the calendar (10/3/1924) the non-schismatic Orthodox (ironically misnamed “Old Calendarists”), suffering persecution, assembled at night on Mount Hymettus, above Holargos. It being the eve of the Feast of the Exaltation of the Holy Cross, they prepared to keep vigil most of the night to secretly celebrate the feast. Around 11:30 p.m there appeared in the sky a very white and brilliant cross, the light of which focused ONLY on the monastery and the yard around it. This confirmed that God wanted the people to follow the old patristic calendar. This miracle was observed not only by the Orthodox congregation but by the very police officers who had been sent to disperse them.”
