Abstract
"In the sweat of your face you will eat bread" - this well-known biblical imperative from the Book of Genesis is best suited to the general characteristics of the life path of the famous Ukrainian scholar and theologian Ivan Ivanovich Ogienko, also known as Metropolitan Ilarion. All his long enough life, from early childhood to his death, he worked for the benefit of his native Ukrainian people, expressing his hard work one of the most significant of his existential traits. Maybe that's why Christianity came to the liking of the ancient ancestors of Ukrainians, who called for individualization through the hard work they never frightened, because they found in it not only livelihood but also the joy of unlucky fate. In the image of his widowed and hard-working mother, Ivan Ogienko saw the fate of the entire enslaved Ukraine and, from an early age, firmly believed that only a conscientious work for the good of his people could earn the right to God's reward. "Serve the people, then serve God!" became the main life principle of I. Ogienko, the amazing hard work of which requires a separate and meticulous scientific research.
