The party ideologues of the Soviet totalitarian state artificially developed and actively introduced into the life of the titular nation of the Ukrainian SSR a new Soviet ritualism, the main goal of which was to raise from every Ukrainian a Russified citizen of the Soviet type without national identity and religious beliefs, with a Russian consciousness, mentality and language. The article proves that the ancient church and religious traditions and customs of the Ukrainian people continued to be a part of the everyday culture of Ukrainians. The religious activity of representatives of the Ukrainian ethnic group was especially observed during the celebration of Christmas, Epiphany, Easter and other church holidays. And although the number of adherents of religious rites in the republic was different – from less in the East to more in the West, Christian values, despite atheism, continued to be the basis of the spiritual life of the absolute majority of Ukrainians.
