Jerome, Saint. [Letter to Principia] in Sancti Eusebii Hieronymi Epistulae ep.65

[Letter from Jerome to Principia]
In this letter, an interpretation of the fourty-fourth psalm written at Principia's request, Jerome strongly defends himself for writing to women: it is women who ask him the questions about scripture, and since the bible has many examples of women who taught, there is no reason not to teach women. Then he interprets the psalm, a greeting to a prince on his wedding day, as a panegyric on virginity, verse by verse.
