"For the Apostle says that a woman does better if she does not marry." - St. Thomas Aquinas on 1 Timothy 2
Gregory of nαzιanzus interpreted the "childbearing" in 1 Timothy 2:15 in a spiritualized or allegoric sense, referring to the bearing of spiritual fruit, rather than physical motherhood being the literal means of a woman's personal salvation.
This approach was common among many early Church Fathers (including Gregory of Nyssa and Origen) who shared Gregory's ascetic sensibilities and were anxious about the literal interpretation of the passage, which seemed to conflict with the high value they placed on virginity and celibacy as a superior spiritual path.
In other words, it's not the childbearing that will save her soul.
I gave qualifications earlier on. You are either a clumsy reader or just trying to stir trouble.
It cannot be an absolute obviously, but the natural leads into the supernatural, and for most women the actual act of bearing physical children is that immediate means of saving her soul. With the already outlined qualifiers.
