 Margaret MacDonald says Celsus' study of Christian scripture led him to focus on Mary Magdalene as the witness to the resurrection, as someone deluded by the "sorcery" by which Jesus did miracles, and as someone who then becomes one of Jesus' primary "instigators" and "perpetrators".MacDonald explains that, "In Celsus' work, Mary Magdalene's role in the resurrection story denigrates its credibility... From beginning to end, [Celsus says] the story of Jesus' life has been shaped by the 'fanciful imaginings' of women" thus lending enemy attestation to the importance of women in the early church and of Mary Magdalene herself.MacDonald sees this negative view of Mary as reflecting a challenge taking place within the church of the second century.
