Jerome, Saint. [Letter to Paula, 384] in Sancti Eusebii Hieronymi Epistulae ep.33

[Letter from Jerome to Paula]
Jerome answers Paula's request for a detailed bibliography of Origen's works. Written before his own change of mind, the letter includes an angry attack on those who call Origen a heretic. Nonetheless, he is careful to write, as he notes, at night and by his own hand, not trusting the material even to his secretary. The task of copying out such a list is a tribute to Jerome's love for Origen or Paula or both.
