Tertullian

“ As what comes to thee as a fit expression of thy strong hatred of him, thou callest the man a dæmon who annoys thee with his filthiness, or malice, or insolence, or any other vice which we ascribe to evil spirits. ”

“ In expressing vexation, contempt, or abhorrence, thou hast Satan constantly upon thy lips; [3] the very same we hold to be the angel of evil, the source of error, the corrupter of the whole world, by whom in the beginning man was entrapped into breaking the commandment of God. ”
