Pammachius
Pammachius (died c. 409 AD) was a Roman senator who is venerated as a saint in the Eastern Orthodox and Roman Catholic Churches.
Biography
Pammachius was born to a noble Roman family. In youth he frequented the schools of rhetoric with St. Jerome, and in 385 he married Paulina, second daughter of St. Paula.
He was probably among the viri genere optimi religione præclari, who in 390 denounced Jovinian to Pope St. Siricius. When he attacked St. Jerome's book against Jovinian for prudential reasons, Jerome wrote him two letters thanking him; the first, vindicating the book, was probably intended for publication.
On Paulina's death in 397, Pammachius became a monk, that is, put on a religious habit and gave himself up to works of charity. In 399 Pammachius and Oceanus wrote to St. Jerome asking him to translate Origen's De Principiis, and repudiate the insinuation of Rufinus that St. Jerome was of one mind with himself with regard to Origen. St. Jerome replied the following year. In 401 Pammachius was thanked by St. Augustine for a letter he wrote to the people of Numidia, where he owned property, exhorting them to abandon the Donatist schism. Many of St. Jerome's commentaries on Scripture were dedicated to Pammachius.
