This book by Ioannis El. Emiris was published to mark 100 years since the founding of the two towns, Nea Filadelfeia and Nea Chalkidona. The luminous figure of the holy martyr Metropolitan Chrysostomos and of the holy hierarchs Grigorios, Efthymios, Prokopios and Platon must remain alive within us, not only so that we honour their heroic life and their martyr’s death, but also so that we strengthen our own values and principles. This book records concisely, yet with full documentation, the course and work of people whose sole aim in life was to instil and preserve Orthodox Christian values in difficult times, together with their unwavering faith in the ideals of Hellenism.
