The paper discusses the issue of love, the essence of holiness, according to Benedict XVI’s encyclical letter Deus caritas est. The encyclical does not deal directly with the question of holiness, but it speaks about various dimensions of love, therefore the question of holiness is always present in it. Referring to the Bible, the encyclical shows first God as the source of love, then man as the one gifted with love by God and at the same time called to witness to it. The encyclical speaks much about the development of love, its ecclesiastic and charismatic character.
