Pope Gelasius I apparently condemned the practice of women officiating at altars; inscriptions near Tropea in Calabria refer to “presbytera”, which could be interpreted as a woman priest or as a wife of a male priest.[9] Furthermore, a sarcophagus from Dalmatia is inscribed with the date 425 and records that a grave in the Salona burial-ground was bought from presbytera Flavia Vitalia: selling burial plots was at one time a duty of presbyters.[9] There have been some 15 records so far found of women being ordained in antiquity by Christians; the church, as noted, states those ordinations were by heretical groups, while the Women’s Ordination Conference contends those same groups were orthodox.[9]

So how should we understand these groups as “heretical”? For example, a good indication would be if a group were indeed Gnostic and so totally against apostolic Christianity. But I wonder if any of these 15 records or so are related to apostolic Christian churches??
So the fact is early Christians sometimes ordained women to be priests. But the issue is: Were these ordinations from the begging, or did these represent a later aberration? Also, were they confined to readily-identified non-orthodox, non-apostolic churches, or were they indeed part of otherwise orthodox churches?
