According to Ivanits, written sources from the Middle Ages leave no doubt whatsoever that the common Slavic peoples continued to worship their indigenous deities and hold their rituals for centuries after Kievan Rus' official baptism into Christianity, and the lower clergy of the newly formed Orthodox Christian church often joined the celebrations. The high clergy repeatedly condemned, through official admonitions, the worship of Rod and the Rozhanitsy (God and the Goddesses, or Generation and the generatrixes) with offerings of bread, porridge, cheese and mead. Scholars of Russian religion define Rod as the general power of birth and reproduction and the Rozhanitsy as the mistresses of individual destiny. Kagarov identified the later Domovoi, the god of the household and kinship ancestry, as a specific manifestation of Rod. Other gods attested in medieval documents remain largely mysterious, for instance Lada and her sons Lel and Polel, who are often identified by scholars with the Greek gods Leda or Leto and her twin sons Castor and Pollux. Other figures who in medieval documents are often presented as deities, such as Kupala and Koliada, were rather the personifications of the spirits of agrarian holidays.
