Kontoglou's efforts to restore Byzantine iconography in Greece were, of course, quite commendable, and he held some other pious and Orthodox views, however, some of his other statements and views I simply cannot concur with or endorse, such as the following. I see no reason to accept this notion that the Greek Revolution was "spiritual" and "sanctified."
I follow the Kollyvades Fathers and St. Athanasios Parios (+1813), who implored the Greeks not to revolt. In my view, modern-day Greeks are mistaken and confused with their celebrations of the Greek Revolution, which I do not regard as "spiritual" or "blessed" or "sanctified" by God. I would be open to the Greeks, or anyone for that matter, to prove otherwise.
Kontoglou, in his book Suffering Romiosini, writes:
"The Greek Revolution is the most spiritual revolution to ever occur in the world. It is sanctified. The slavery which pushed the Greeks to rise up against the Turk was not only about the deprivation and evils against the body, but, above all, the tyrant wanted to ruin their Faith, bothering them with their religious debts, changing their Faith and slaughtering and hanging them, because they did not deny their Faith to become Mohammedans. For them Faith and Homeland became one and the same thing, and the freedom they longed for was not only the freedom all revolutionaries long for, but it was the freedom to preserve their sacred Faith, with which they hoped to save their souls. Because for them, though near to the body which has many needs and with its suffering requires maintenance, there also existed a soul, which Christ said is worth more than the body...."
