Ante-Nicene Fathers: Volume IV. Fathers of the Third Century: Tertullian, Part Fourth; Minucius Felix; Commodian; Origen, Parts First and Second.
The Ante-Nicene Fathers, subtitled "The Writings of the Fathers Down to A.D. 325", is a collection of books in 10 volumes (one volume is indexes) containing English translations of the majority of Early Christian writings. The period covers the beginning of Christianity until before the promulgation of the Nicene Creed at the First Council of Nicaea. The translations are very faithful, but sometimes rather old-fashioned.
