Venerable English translations from the 38-volume collection divided
into three series: Ante-Nicene (ANF), Nicene and Post-Nicene Series I
(NPNF1), and Nicene and Post-Nicene Series II (NPNF2), courtesy of
Wheaton College. The site New Advent: Fathers of the Church (http://www.newadvent.org/fathers/) is similar and draws on the same translations.
