This contribution analyzes two different early testimonies on the power of women in the first centuries in Early Christianity. In the first section, the author discusses how Luke applies priestly attributes to the prophetess Anna to extol her, while Revelation connects priestly attributes with female prostitution and pseudo-prophecy to describe the degeneration of John's adversaries, Jewish (or Jewish-Christian) authorities. In the second section he studies the case of women concelebrating Gnostic eucharist and prophesying in the church of Marcus "the Magician", as told by Irenaeus. He finally hypothesizes that the fear of women priests in orthodox confessions is connected with ritualized sexual activities that, according to the heresiologists, were constitutive of the religious life of minority groups.
