Tertullian addressed women in these words: "Do you not know that you are each an Eve? The sentence of God on this sex of yours lives in this age. ... You are the devil's gateway. ... You destroy God's image, Man."[35: Bk.1.] Thus woman became degraded beyond all previous thought in the teaching of the early church. The child was looked upon as the result of an act of sin, and came into the world tainted through its mother with sin. At best marriage was a vice. All the church could do was to cleanse it as much as possible by sacred rites, an attempt which harked back to the origin of marriage as the ceremonial breaking of taboo. Peter Lombard's Sentences affirmed marriage a sacrament. This was reaffirmed at Florence in 1439. In 1565, the Council of Trent made the final declaration. But not even this could wholly purify woman, and intercourse with her was still regarded as a necessary evil, a concession that had to be unwillingly made to the lusts of the flesh. Such accounts as we have of the lives of holy women indicate that they shared in the beliefs of their times. In the account of the life of a saint known as the Blessed Eugenia preserved in an old palimpsest[36] we read that she adopted the costume of a monk,--"Being a woman by nature in order that I might gain everlasting life." The same account tells of another holy woman who passed as a eunuch, because she had been warned that it was easier for the devil to tempt a woman. In another collection of lives of saints is the story[37] of a holy woman who never allowed herself to see the face of a man, even that of her own brother, lest through her he might go in among women. Another holy virgin shut herself up in a tomb because she did not wish to cause the spiritual downfall of a young man who loved her.
