Witchcraft and Heresy — The Inquisition's Deadly Equation

The transformation of witchcraft from a folk superstition into a prosecutable heresy was one of the most consequential developments in European legal and religious history. Prior to the 15th century, the official Church position, established by the 'Canon Episcopi' (circa 906 AD), held that belief in witchcraft was itself a form of superstition — an illusion fostered by the Devil. This position effectively prevented prosecution. The reversal came gradually, driven by inquisitors who argued that the Canon Episcopi was outdated and that witchcraft had evolved into a new, organized form of Devil worship. Pope Innocent VIII's 1484 bull and the subsequent 'Malleus Maleficarum' completed the transformation. Once witchcraft was classified as heresy rather than superstition, the full apparatus of ecclesiastical and secular justice could be brought to bear. Heresy was a crime not merely against society but against God — the ultimate offense, deserving the ultimate punishment. This theological escalation converted local disputes between neighbors into cosmic battles between good and evil.
