For 2000 years, the Roman Catholic Church has written (in Latin) about its opponents, and in particular about the servants of the Devil. During the beginning of Christianity, there were many arguments and discussions with gnostics and with pagans, both of which were described as worshiping the Devil. Later, in the Middle Ages, the Church wrote about heretics, witchcraft, and blasphemous groups within its own ranks.

De Haeresibus
(Augustine of Hippo 354-430, describes a ritual performed by a group he calls Catharistas, in which flour is placed beneath a man and a women during sexual intercourse, so that their sexual fluids may be mixed with the flour to be used in making a Host, which was then believed to contain the spiritual light.)
