Jerome, Saint. [Letter to Paula and Eustochium, 388 (2)] in Commentarius in Epistolam ad Galatas 307-308, 399-411, 308-12

[Letter from Saint Jerome to Paula and Eustochium]
Jerome composed this commentary at the request of Paula and Eustochium, to whom he addresses the prologue. But when Marcella's mother died, he decided to send it also to her as he explains. The prologue analyzes Paul's lessons in terms of his audience. Jerome also addresses Paula and Eustochium by name at the beginning of the third book in a separate and rather personal letter describing his physical state and apologizing for his style.
